ESS Education: Hiring, Background Check & Employment Verification FAQs

ESS was founded in 2000 in New Jersey as a secondary source of substitute staffing, beginning with 150 substitute employees serving 17 partnering school districts. It is headquartered in Cherry Hill, New Jersey. From that single-state start the company expanded steadily: into a seventh New Jersey county with its 65th district partnership by 2003, into a full-service substitute program including long-term placements by 2006, and into permanent paraprofessional staffing by 2010.

Geographic growth followed through the 2010s and 2020s, with expansion into Pennsylvania in 2013, Connecticut, Virginia, and Georgia in 2014, South Carolina, Tennessee, and Rhode Island in 2016, and a long list of additional states through 2025, when the company added Minnesota. Private equity has backed that expansion: Nautic Partners, LLC made a significant investment in 2015, and The Vistria Group became a majority investor in 2022.

The company has also grown by acquisition and now operates as a family of companies. It purchased Proximity Learning, a virtual instruction provider, and Enriched Schools, which supplies guest educators to charter schools, in 2019. It acquired Academic Staffing, a provider of therapy services to K-12 districts, in 2023, and rebranded that business as ESS Clinical in 2025. Also in 2023 it acquired PSI, which offers school health, social and behavioral health, and special education support services. The company developed its own application, absence management, and time tracking software, willsub+, in 2018.

By the company's own account it serves more than 1,200 school systems nationwide, supports more than 8.5 million students, employs 100,000 substitute and permanent school personnel alongside roughly 900 corporate employees, and fills about 35,000 positions each day across some 15,000 schools. Roles span daily and long-term substitute teachers, substitute and permanent paraprofessionals including special education and one-to-one aides, school secretaries and clerical staff, food service and transportation aides, and clinical positions such as speech language therapists, occupational and physical therapists, school psychologists, and counselors.

Company culture and employee programs:

ESS puts a visible emphasis on credentialing support and recognition programs for a workforce that is largely made up of part-time and day-to-day employees. The company developed its first copyrighted training manual in 2011, created an annual Impact Award in 2014, launched a paid employee referral program in 2017, and introduced a Career Kickstart Incentive in 2023 to help newly hired employees with the cost of obtaining credentials. It has also partnered with Accelerate Learning to offer discounted professional certificate opportunities through the National Institute for STEM Education. Pay rates, scheduling, and benefit eligibility vary widely by state, district contract, and role, so candidates should confirm details with their local ESS recruiter.

Yes. Employers in the education staffing industry, including ESS, are legally permitted to conduct pre-employment background checks on job candidates, and in school settings they are frequently required to do so. In the United States, background screening obtained through a consumer reporting agency is governed by the Fair Credit Reporting Act (FCRA), which sets rules for candidate disclosure, written authorization, and the adverse action process. Layered on top of that, state education codes and district policies commonly mandate fingerprint-based criminal history checks and other clearances before an adult may work in a school.

ESS is generally reported to conduct background checks as part of its hiring process, and school staffing is one of the most consistently screened segments of the labor market. Requirements are typically driven by state law and by the contract between the staffing company and the school district, not by employer preference alone. The specific components of an ESS Education background check vary considerably by state, because each state sets its own rules for who may work in a school and what clearances are required.

Steps differ by state and role, but the sequence is usually recognizable. Candidates apply online, and qualified applicants are contacted for a phone screen or an interview with a recruiter. Substitute teaching candidates typically need to meet the education and credential requirements their state sets, which may mean a bachelor's degree, a set number of college credits, a high school diploma, or a state-issued substitute permit depending on the jurisdiction. Candidates then complete onboarding, which generally includes fingerprinting and any state-required clearances, consent to a background check, and orientation or training before their first assignment. Clinical roles additionally require verification of professional licensure.

Timelines depend on the searches ordered and, importantly, on state clearance processing. A commercial background report often returns within a few business days, but fingerprint-based state and federal criminal history checks are processed by state agencies and the FBI on their own schedules, which can add days or weeks. Candidates applying close to the start of a school year should expect heavier processing volumes. For context on what drives employment screening timelines generally, see this explanation of background check turnaround times.

Scope depends on the state, the district contract, and the role. Screening for school-based positions may include some or all of the following:

Candidates should read the disclosure and authorization paperwork they receive, since it states exactly which searches apply to their assignment and state.

The lookback window depends on the instrument. Under the FCRA, consumer reporting agencies are generally restricted from reporting most adverse information older than seven years, with exceptions that include criminal convictions and higher-salary positions, and several states impose stricter limits. Fingerprint-based state and FBI criminal history checks used for school employment are not bound by that seven-year framing and can surface older records. Many states also maintain lists of offenses that permanently disqualify a person from school employment regardless of how long ago they occurred.

There is no single answer, because eligibility for school-based work is substantially set by state law rather than by the staffing company. Most states define categories of offenses that disqualify an individual from working in a school, often permanently for serious offenses involving children, violence, or certain drug crimes, while other records may be evaluated individually. Where discretion exists, common considerations include the nature and seriousness of the offense, how much time has passed, evidence of rehabilitation, and the duties of the role. Many states and cities have adopted "ban-the-box" laws that limit when employers may ask about criminal history, though school employment is frequently carved out of those rules. Candidates should answer all disclosure questions honestly, since school clearance processes treat omissions seriously.

Candidates are typically asked to sign a written disclosure and authorization form before a background check is initiated, and to complete separate state clearance applications where required. Applicants should be prepared to provide full legal name, date of birth, Social Security number, and address history, to appear in person for fingerprinting, and to supply transcripts, diplomas, or credential documentation where the role has an education requirement. Clinical candidates should have current license details available. Accurate and complete information keeps searches in the correct jurisdictions and helps avoid delays that could push back a first assignment.

The Fair Credit Reporting Act is the federal law that governs how consumer reporting agencies collect, assemble, and share background check information. Under the FCRA, an employer must obtain written consent before ordering a report, must provide the candidate with a copy of the report and a summary of rights before taking adverse action based on it, and must allow a reasonable opportunity to dispute inaccurate information before making a final decision. For a fuller explanation of how the FCRA and Equal Employment Opportunity Commission (EEOC) guidance apply to employment screening, see this introduction to the Fair Credit Reporting Act (FCRA).

School employment sits under a separate body of state law from ordinary private-sector hiring, and that is the main reason screening here looks different. Depending on the state, an adult working in a school may need fingerprint-based state and federal criminal history clearance, a child abuse or neglect registry check, a state substitute teaching permit or credential, tuberculosis testing or another health clearance, and mandated reporter training. Some of these clearances are portable between districts within a state and some are not, and several must be renewed on a fixed schedule. Because requirements vary so much by state, candidates should treat the onboarding checklist their recruiter provides as the authoritative list for their situation.
