A charter network preparing to open a new campus may need to fill teacher, paraprofessional, school nurse and substitute positions by the same opening date. When each role runs through a different vendor, school leaders end up managing inconsistent candidate screening, credentialing updates and reporting. Field trips, extended-day programs and new-campus launches add even more scheduling pressure.
This guide to the best charter school staffing agencies compares specialist and national providers on charter-specific evidence, not general reputation. The strongest partner does more than post a vacancy. It should source hard-to-find professionals, coordinate several campuses at once, and build a repeatable candidate pipeline for recurring vacancies.
Charter schools remain subject to federal requirements such as ESSA and IDEA, while teacher-certification rules, authorizer expectations, and operational flexibility vary by state. A staffing partner also needs to understand how the network makes hiring decisions, which funding sources may support contracted personnel and what procurement process must be completed before services can begin.

What is the best charter school staffing agency?
Focused Staffing Group stands out as the strongest overall option for charter schools and growing networks. It builds one candidate pipeline across special education, paraprofessional, nursing and substitute roles. Its model suits networks that want one staffing relationship and candidates who are not simultaneously developed for a direct local competitor. Both temporary and permanent hiring options remain available.
Teachers On Demand is a strong charter-focused choice for substitute management and broader instructional or operational recruitment. ESS and Kelly Education fit large managed substitute and support-workforce programs well. Soliant, Amergis Education and Epic Special Education Staffing cover broader special education, nursing, therapy and behavioral needs. Zen Educate is a technology-led pick for substitutes and paraprofessionals in supported markets.
No single agency fits every role mix or operating model.
How We Evaluated Charter School Staffing Agencies
Every agency was assessed using publicly available information about direct charter-school evidence, multi-campus capacity and K-12 specialization. We also considered teacher, substitute and special education staffing, paraprofessional and behavioral coverage, and school nursing or related services. Additional factors included administrative recruitment, staffing-model flexibility, credentialing support, candidate-pipeline structure, account ownership, geographic reach and reporting capacity.
Disclosure: Focused Staffing Group publishes this comparison and is ranked first based on the criteria described above. It was evaluated using the same publicly available evidence standards applied to every agency listed. Each entry reflects the staffing needs it appears best equipped to support. Charter organizations should confirm current rates, role availability, contract terms, credentialing responsibilities, and local candidate activity directly with each provider.

1. Focused Staffing Group: Best Overall for Dedicated Charter-School Talent Pipelines
Focused Staffing Group serves charter schools and other K-12 organizations through FocusedEDU, its education staffing division. Founder Robert Flom established the company after working as a K-12 classroom music teacher, giving its education staffing model direct grounding in school operations. The company treats charter hiring as one coordinated plan rather than a series of separate requisitions.
Focused Staffing Group's K-12 services cover special education teachers, paraprofessionals, school nurses, substitutes, and related-service providers. The company builds one candidate pipeline around those connected needs instead of treating every role as a separate search.
Focused Staffing Group assigns its recruiters to one organizational partner within a market boundary agreed at the start of the engagement, based on the network’s service area and recruiting geography.
The team works only that partner’s pipeline and does not accept another organizational partner within the agreed boundary while the engagement remains active. If a competing charter network approaches Focused Staffing Group, the company first determines whether it falls inside that boundary before discussing availability.
Focused Staffing Group presents candidates within two weeks, although credentialing and start timelines vary by role. VerifAI, the company’s own credentialing platform, supports the credentialing process once a candidate is selected. Its temp-to-permanent option carries no conversion fee under the standard model, letting a school evaluate a professional before making a permanent offer.
Focused Staffing Group names Chester Community Charter, Odyssey Charter School, Leadership Public Schools and Breakthrough Public Schools among its charter partners. In its work with Odyssey Charter School, the company reports reducing the vacancy rate from 35% to under 10% and increasing the substitute fill rate by 25%. These results reflect one named partnership and should not be interpreted as guaranteed outcomes for every charter network.
Where it fits best:
- Independent charter schools
- Charter management organizations
- Multi-campus charter networks
- New-school openings
- Networks entering another market
- Organizations with recurring special education vacancies
- Schools needing paraprofessionals and substitutes
- Charter leaders reducing vendor fragmentation
- Schools and charter networks across multiple states, subject to current market availability
What to verify: Focused Staffing Group works with one organizational partner per local market. Charter schools should confirm current market availability, role coverage, credentialing requirements and contract terms directly with the company.
Build a charter-school candidate pipeline that is not shared with a direct local competitor. Book a discovery call with Focused Staffing Group to discuss your campuses, open roles and current market availability.
2. Teachers On Demand: Best for Charter-Focused Recruitment and Substitute Management
Teachers On Demand places substitute teachers, paraprofessionals, support staff, administrative professionals and school leaders in K-12 schools nationwide. Its site features testimonials from named charter schools, including Pine Springs Preparatory Academy and Roots Public Charter School.
The company's temp-to-permanent pathway covers teachers, paraprofessionals, support staff, administrative professionals and school leaders across general, special and bilingual education. That model lets a school evaluate a professional before converting the placement to a permanent hire.
Where it fits best:
- Charter schools needing managed substitutes
- Organizations recruiting teachers and paraprofessionals
- Schools hiring administrators or operational staff
- General, special and bilingual education hiring
- Temporary-to-permanent pathways
- Individual schools and smaller networks seeking a K-12 specialist
What to verify:
- Exact role availability by market
- Whether one team coordinates all campuses
- Whether candidate pools are shared
- Multi-campus reporting
- Credentialing responsibilities
- Substitute scheduling and call-out procedures
- Temp-to-permanent conversion terms
- Experience with the network's state charter requirements
3. ESS and Enriched Schools: Best for Managed Substitute and Paraprofessional Programs
ESS recruits, hires, trains and supports substitute teachers, paraprofessionals and school support staff for districts nationwide. Enriched Schools, an ESS brand, focuses specifically on substitute teachers for charter schools.
In 2026, ESS announced a partnership with Rocky Mountain Prep, a Colorado charter network serving more than 5,650 students across 12 schools. That engagement covers substitute teachers and paraprofessionals across the full network. Because Enriched Schools operates as an ESS brand, the two are evaluated here as one provider.
Where it fits best:
- Large substitute programs
- Multi-campus charter networks
- Paraprofessional staffing at volume
- Networks outsourcing recruiting, hiring and workforce administration
- Charter systems requiring daily, long-term or building-based substitutes
What to verify:
- Permanent teacher recruitment
- School nurse availability
- Therapists and clinical roles
- Special education teacher coverage
- Leadership recruitment
- Whether candidates are shared
- Campus-level reporting
- Replacement and absence-management procedures
4. Kelly Education: Best for Enterprise Education Workforce Management
Kelly Education supports more than 10,000 schools and offers recruiting, hiring, scheduling, payroll, benefits administration and workforce reporting. Its role coverage spans substitute teachers, paraeducators, school nurses and other instructional and non-instructional staff.
Kelly Education's published K-12 services emphasize large-scale workforce management. Charter networks should request references from comparable organizations and confirm how implementation, account ownership and reporting would work across their campuses.
Where it fits best:
- Large charter management organizations
- Multi-state education organizations
- Managed substitute programs
- Paraeducator programs
- Networks outsourcing scheduling or payroll administration
- Organizations needing broad non-instructional coverage
- Networks prioritizing workforce-management infrastructure
What to verify:
- Whether the charter network receives a dedicated team
- Candidate-sharing practices
- Permanent teacher and leadership recruitment
- Special education specialist availability
- Reporting by campus
- Urgent specialist-vacancy procedures
- Local nurse and paraprofessional activity
- Implementation responsibilities and timelines
Kelly's scale is real, but national size alone does not prove active candidate availability in a particular charter market.
5. Soliant: Best for Special Education and Related-Service Staffing
Soliant's school staffing pages list special education teachers, paraprofessionals, school nurses, BCBAs, RBTs, therapists, school psychologists and social workers. The company supports contract and direct-hire placements through dedicated account and credentialing teams.
Soliant advertises a nationwide pool of more than 27,000 paraprofessionals. That figure describes a company-wide count, not active candidates available in a specific charter network's commuting area.
Where it fits best:
- Charter networks with difficult special education vacancies
- Schools needing nurses, therapists or psychologists
- Behavioral and related-service hiring
- Paraprofessional recruitment
- Multi-campus student-support programs
- Contract or direct-hire specialist searches
- Teletherapy requirements
What to verify:
- Current candidates within commuting distance
- Recent charter-school placements
- Time to first qualified submission
- Candidate engagement status
- Account coordination across campuses
- Retention and replacement terms
- Whether candidates are shared
- State certification and licensure support
6. Amergis Education: Best for Multidisciplinary Clinical and School Staffing
Amergis Education lists teaching, nursing, therapy, behavioral and support-staff services, plus school administration. The company reports more than 700 recruiters nationwide and describes more than 100 dedicated education teams available for last-minute or longer-term placements.
Amergis's national recruiting infrastructure may support multi-campus hiring, but charter networks should confirm whether one education team will coordinate every campus, role category and reporting requirement.
Where it fits best:
- Networks needing several clinical disciplines
- School nurse and behavioral staffing
- Special education and student-support programs
- Multi-campus therapy requirements
- Organizations wanting local teams backed by national infrastructure
- Last-minute and longer-term assignments
What to verify:
- Whether one team coordinates every campus
- Direct charter-school experience
- Candidate-sharing practices
- Instructional and clinical recruitment under one account
- Consolidated reporting
- Substitute-program capabilities
- Account ownership after placement
- Clinical oversight by role
7. Epic Special Education Staffing: Best for Specialist School-Based Roles
Epic Special Education Staffing lists special education teachers, school nurses, BCBAs, RBTs, behavioral interventionists, therapists, school psychologists and special education administrators. Its confirmed specialty is school-based clinical and special education staffing rather than general workforce outsourcing.
Networks should confirm general education teacher recruitment, substitute programs and network-wide reporting directly, since those are not the company's clearest published strengths.
Where it fits best:
- Special education departments
- Charter schools with clinical vacancies
- Networks needing nurses or therapy professionals
- Behavioral-support programs
- Local or travel assignments
- Short- and long-term contracts
- Special education leadership vacancies
What to verify:
- General education teacher recruitment
- Substitute and paraprofessional programs
- Administrative roles outside special education
- Network-wide workforce management
- Multi-campus reporting
- Credentialing and clinical-supervision structures
- Current local candidate activity
8. Zen Educate: Best Technology-Led Option for Substitutes and Paraprofessionals
Zen Educate pairs a matching platform with dedicated account managers to fill substitute, paraprofessional and special education aide roles. Its published charter case studies report an 87% fill rate for a Minnesota charter network. A separate case study cites a 95% short-term and 100% long-term fill rate for LIFE Prep in St. Paul.
Both case studies describe company-reported outcomes for specific schools, not guaranteed results for every network. Zen also offers temp-to-permanent hiring. Its public pages describe different conversion-fee conditions, so schools should confirm the applicable timing and fees in writing before using that pathway.
Where it fits best:
- Charter schools needing daily substitutes
- Short- and long-term teacher coverage
- Paraprofessional and special education aide staffing
- Networks comfortable with technology-led matching
- Schools wanting direct candidate visibility
- Temp-to-permanent hiring
What to verify:
- Geographic availability for every campus
- Special education teacher coverage
- School nurses and clinical professionals
- Leadership and operational recruitment
- Multi-campus planning and reporting
- Dedicated account ownership
- Conversion fees and timing
- Whether the platform can expand into an unsupported market
Agencies Not Included in the Main Ranking
Swing Education is a credible substitute-staffing platform covering day-to-day, long-term, special education, bilingual, paraprofessional and support roles. It overlaps heavily with ESS, Kelly and Zen, so it is mentioned here as an additional substitute option rather than ranked separately.
Scoot Education has direct charter-school experience and supports substitute educators and classroom staffing. It is included as an additional option rather than ranked separately because its public model is more concentrated on flexible educator coverage than the broader multi-role staffing evaluated in the main list.
Selected is a K-12 teacher-hiring and matching platform with strong charter-school relevance. It is included as an additional recruiting option rather than ranked as a full-service staffing agency because its model centers on matching schools with candidates rather than administering a contracted workforce.
Edbinder markets directly to charter schools but focuses primarily on bilingual and hard-to-fill teaching recruitment. It is referenced later as a narrow bilingual-teacher option rather than compared as a full-service staffing agency.
How to Choose a Charter School Staffing Agency
Confirm experience with charter operating models
NCES data show that the number of public charter schools increased from approximately 5,300 in 2010–11 to 7,800 in 2021–22.
Charter organizations often run differently than a typical district school. They may have:
- Centralized or campus-level hiring
- Lean internal HR teams
- Rapid enrollment-driven growth
- Multi-campus coordination
- New-school opening deadlines
- Extended-day or extended-year programs
- State-specific certification rules
- Authorizer requirements
- Specialized instructional models
Ask an agency directly:
- How many charter schools or networks do you currently support?
- Can you provide references from a similar organization?
- Have you staffed a new school opening?
- Can central-office and campus leaders submit requests?
- Do you understand the applicable state charter law?
- Can one account structure cover every campus?
Charter and district schools are not opposing systems. They share most of the same staffing challenges, just with different operating structures.
Compare role coverage
Because K-12 education staffing may involve instructional, student-support and operational positions, group the roles into three categories before comparing agencies.
Instructional: general education teachers, special education teachers, interventionists, bilingual or ESL teachers, long-term substitutes, daily substitutes and tutors.
Student support: paraprofessionals, one-to-one aides, behavior technicians, school nurses, school psychologists, counselors and social workers, SLPs, OTs and PTs, BCBAs and RBTs.
Leadership and operations: school leaders, special education administrators, HR professionals, administrative staff, IT and operations staff, and food-service and facilities workers.
A strong substitute vendor may not support clinicians or permanent leaders, so match the agency to the category that matters most now.
Evaluate multi-campus capacity
Ask the agency:
- Can you coordinate requisitions across campuses?
- Will the network have one account leader?
- Can school leaders submit requests directly?
- Is reporting available by campus and role?
- Can a new-campus launch receive priority?
- Can consistent screening standards be maintained?
- Can invoices be consolidated?
- Can credential expirations be tracked centrally?
- What happens when campuses want the same candidate?
The National Alliance for Public Charter Schools maintains data covering more than 7,800 charter schools and campuses, including individual schools, networks, authorizers and management organizations. Staffing capacity should therefore be evaluated against the organization's actual campus structure rather than a generic school model.
Examine the candidate-pipeline model
| Pipeline model | How it works | Main consideration |
|---|---|---|
| Shared database | Candidates may be marketed to several schools | Broad reach but more direct competition |
| Open-requisition recruitment | Recruiters source for each vacancy | Flexible but often transactional |
| Managed workforce pool | Agency recruits and administers recurring staff | Useful for substitutes and high-volume roles |
| Exclusive local pipeline | Recruiting resources are dedicated to one partner | Greater ownership but market availability may be limited |
An exclusive local pipeline, such as Focused Staffing Group's one-partner-per-market model, dedicates recruiting resources to one network rather than marketing candidates broadly.
Database totals can include historical applicants, inactive candidates and professionals outside commuting range. Some listed candidates may already be working, or being submitted to other schools at the same time.
Ask instead for active candidates by role and location, recent placements and time to first qualified submission. Also request offer acceptance, start rate, retention and the agency's candidate-sharing policy.
Review special education capability
Ask whether the agency recruits:
- Special education teachers
- Paraprofessionals and one-to-one aides
- Behavior technicians, BCBAs and RBTs
- School psychologists and therapists
- School nurses and other related-service professionals
The agency should also understand:
- Role-specific state credentials
- IEP-related service continuity
- One-to-one assignment requirements and supervision rules
- Child-safety clearances
- Extended school-year staffing
- Replacement coverage for specialist roles
No staffing agency can guarantee IDEA or FAPE compliance. Under IDEA's personnel qualifications rule, related-service personnel must meet the state-approved or state-recognized certification, licensing, registration or comparable requirements that apply to their discipline.
Public charter special education teachers must meet the certification or licensing requirements, if any, established by the state's public charter school law. That charter-specific provision does not remove the state qualification requirements that apply to related-service professionals such as school nurses and SLPs.
Examine credentialing and compliance support
Confirm coverage for:
- Teaching certification and professional licensure
- Background checks, fingerprinting and child-abuse clearances
- Education and reference verification
- Health records and mandated-reporter training
- Role-specific competencies
- Credential renewal tracking
- Network-specific onboarding
Ask which checks the agency completes, which remain the school's responsibility, and what the role-specific credentialing timeline looks like. Also ask who tracks expirations, whether the network can see credential status, and how different state requirements are handled.
Charter networks running a formal vendor evaluation can also review education staffing RFP documentation that lists the same categories to score. Avoid accepting "fully credentialed" as a vague assurance without specifics behind it.
Compare staffing models
| Staffing model | Best for | Questions to ask |
|---|---|---|
| Daily substitute | Short-term absences | Is same-day or next-day coverage available? |
| Long-term substitute | Leave or persistent vacancy | Can the worker convert permanently? |
| Contract staffing | Defined school-year requirement | Who employs and supervises the worker? |
| Temp-to-permanent | Evaluating fit before hiring | Is there a conversion fee? |
| Direct hire | Permanent teachers or leaders | What replacement guarantee applies? |
| Managed substitute program | Network-wide absence coverage | Who owns recruiting, scheduling and payroll? |
| Recruitment process outsourcing | Large recurring hiring plans | Which internal functions will be handled externally? |
| Project hiring | New-campus or market launch | Can the agency meet opening milestones? |
Measure hiring speed correctly
No agency should be called universally fastest. Compare agencies on:
- Time to first qualified submission
- Interview-to-offer time and offer acceptance
- Credentialing time and acceptance-to-start time
- Candidate drop-off and replacement time
- Vacancy age and fill rate by campus
- Retention after 30, 90 and 180 days
A fast candidate submission does not guarantee a fast classroom start. Credentialing and state, authorizer or school-level clearances often determine the actual start date.
Assess account ownership
Ask the agency:
- Who owns the network relationship?
- Does each campus receive a contact?
- Who recruits candidates?
- How many other schools does that team support?
- Who handles urgent vacancies?
- How often are pipeline reports delivered?
- Who manages credentialing?
- Who handles performance problems?
- Who coordinates replacements?
- Is support available outside standard hours?
A school staffing vendor relationship works best when one team, rather than several disconnected recruiters, owns the account across every campus. Vague answers to these questions are a signal to keep comparing agencies rather than sign a contract.
Which Agency Fits Different Charter-School Needs?
Charter schools seeking one multi-role staffing partner: Focused Staffing Group is the strongest choice when the school wants one pipeline covering several hard-to-fill K-12 role categories.
Multi-campus charter networks: Focused Staffing Group fits best when the priority is a single-market pipeline and coordinated multi-role recruitment. ESS and Kelly Education may suit networks that prioritize managed substitute and workforce administration. Amergis or Soliant may be more appropriate when specialist clinical and related-service roles dominate the hiring plan.
New-school openings: Focused Staffing Group may be a strong option when a network needs several role categories recruited against the same campus-opening timeline. The network should confirm launch milestones, credentialing deadlines and market availability before finalizing the staffing plan. The plan should also cover nursing, student support, substitutes, staged start dates and campus-level reporting.
Special education teachers and paraprofessionals: Focused Staffing Group offers a combined pipeline for both roles at once. Soliant covers broad special education and paraprofessional recruitment. Amergis supports multidisciplinary staffing and clinical oversight. Teachers On Demand covers general, special and bilingual education alongside paraprofessionals.
Managed substitute programs: ESS, Kelly Education and Teachers On Demand are the clearest options. Zen Educate may be relevant where the network prefers technology-led booking and direct candidate visibility.
Clinical and related-service roles: Soliant, Amergis and Epic are strongest when the network needs nurses, therapists, psychologists or behavioral specialists.
Bilingual teachers: Teachers On Demand may be relevant for broader bilingual education recruitment. Edbinder may be worth a look as a narrow bilingual-teacher platform, subject to geographic and role availability.
Reducing time to hire: Focused Staffing Group should be evaluated around dedicated sourcing and VerifAI, its proprietary credentialing automation platform, rather than a claim of being universally fastest. Compare time to first qualified submission, credentialing time, candidate starts, and replacement speed across any agency under consideration. Focused Staffing Group's 2026 State of K-12 Staffing report documents broader vacancy and credentialing pressure across schools.
Questions to Ask a Charter School Staffing Agency
- How many charter schools or networks do you currently support?
- Can you provide references from a multi-campus charter organization?
- Which instructional, special education, and support roles do you recruit?
- Can you recruit teachers and paraprofessionals together?
- Do you provide nurses, therapists, and behavioral professionals?
- Can one account support all our campuses?
- Are candidates presented to nearby schools?
- How many active candidates are available for our roles and locations?
- What is your typical time to first qualified submission?
- What is the credentialing timeline for each role?
- Which screening and certification steps do you handle?
- Can you support a new-campus opening?
- Do you offer substitutes, contract staff, temp-to-permanent, and direct hire?
- Is there a conversion fee?
- Who owns our account and recruiting pipeline?
- What happens if a placement leaves or fails to start?
- Can reporting be provided by campus, role and hiring stage?
- How are rates, overtime, cancellation and replacement terms calculated?
Build the Pipeline Around the Network's Growth Plan
Charter networks need more than an occasional résumé. Role mix and operating scale determine the right agency, and substitute management is a different service from permanent recruitment or specialist staffing.
Special education and clinical depth should be evaluated separately from general teacher hiring. A large database does not prove active local availability, and credentialing speed should be measured apart from recruiting speed. Networks should also know whether candidates are being shared with nearby schools.
Focused Staffing Group is the clearest overall pick for charter schools and growing networks. It offers one staffing relationship across special education, paraprofessional, nursing and substitute roles. Its model works best for organizations that value candidate exclusivity and coordinated multi-campus hiring. The pipeline is built around recurring needs rather than one isolated vacancy.
Build a charter-school candidate pipeline around your campuses, role mix and growth plan, not another shared database. Book a discovery call with Focused Staffing Group to discuss current vacancies and market availability.
