A Christian school teacher teaches academics at a K–12 school built on a Protestant Christian mission — evangelical, Baptist, Lutheran, Adventist, classical Christian or nondenominational.
Alongside your subject, you weave a biblical perspective into the classroom, and a school's statement of faith shapes both the teaching and the hiring.
Your credential may be an ACSI certificate, a denominational certification, a state teaching certificate — or a combination, depending on the school and the state.
What does a Christian school teacher do?
A Christian school teacher teaches a subject or grade level at a school whose mission is explicitly Christian.
The academic work — planning, instruction, assessment, grading, parent communication — looks like any K–12 teaching job.
What sets it apart is that faith formation is written into the role, not added on top of it.
The clearest evidence is in the credentialing structure itself.
ACSI, the Association of Christian Schools International, builds its teacher certification around a professional growth plan in three areas — Bible knowledge, educational studies and Christian philosophy of education — and offers a dedicated Bible Specialist certificate alongside its elementary and secondary classroom certificates.
Day to day, that structure translates into a workload that mixes the academic and the spiritual.
Depending on the school, you may lead or attend chapel, pray with students, mentor them in character and discipleship, and connect your subject to the school's statement of faith — a practice known as biblical integration.
The balance varies by school, level and subject.
A Bible teacher's week is built around scripture and doctrine classes, while a middle school math teacher teaches math classes, with devotional life and mentoring around the edges.
An elementary role blends grade-level teaching with pastoral care of one class group, while a high school specialist is anchored in a subject area.
Each school draws the line in its own way.
Evangelical, ACSI, ACCS, Lutheran, Adventist and other Protestant schools
The scale is large.
NCES's Private School Universe Survey counted 13,507 other (non-Catholic) religious private schools in 2021–22 — 45.4% of all US private schools — staffed by 193,878 full-time-equivalent teachers.
NCES subdivides the group into 3,549 conservative Christian schools, 3,441 other affiliated schools and 6,516 unaffiliated religious schools.
By religious orientation, the survey's largest Protestant categories were "Christian (unspecified)" at 4,013 schools and Baptist at 1,476.
The denominational families are substantial on their own: the same survey counted 853 Lutheran Church–Missouri Synod schools, 326 Wisconsin Evangelical Lutheran Synod schools, 85 ELCA schools and 671 Seventh-day Adventist schools.
Several associations organize evangelical schools.
In the survey, 2,298 US K–12 schools reported membership in the Association of Christian Schools International, with 586,647 students and 56,392 teachers at those schools.
The same table lists 727 schools in the American Association of Christian Schools, 315 in Christian Schools International and 671 in Accelerated Christian Education.
Classical Christian schools are a distinct strand with their own curricular tradition: 288 schools reported membership in the Association of Classical and Christian Schools (ACCS), with 57,024 students and 6,750 teachers.
Denominations count themselves differently than NCES does, because their own figures include early-childhood programs.
The Lutheran Church–Missouri Synod, for example, says its congregations operate more than 800 elementary schools, plus more than 1,600 early childhood centers and preschools.
The practical point for a teacher: Lutheran schools sit under different church bodies — the survey counts LCMS, WELS and ELCA schools separately — and each structure sets its own expectations.
NCES counts Catholic schools as their own category in the same survey; this guide covers the Protestant and nondenominational Christian side.
Whichever tradition you look at, the school's governance — church body, synod, association, board or founder — helps shape the statement of faith, the credential expectations and the curriculum you would work under.
Where the numbers on this page come from
Statement of faith and pastor references
A statement of faith is the document that says what a school teaches about God, scripture, salvation and how people are called to live — and, for teachers, a commitment to hold to it.
ACSI states that all of its schools and educators will hold to the ACSI Statement of Faith, and it serves schools from across a range of evangelical Protestant backgrounds.
ACSI's published statement is a useful example of what these documents cover:
- The Bible as inspired, infallible and inerrant.
- The Trinity, and the deity, virgin birth, atoning death and resurrection of Christ.
- Salvation by grace through faith.
- Marriage as the union of one man and one woman, with sexual intimacy only within marriage.
- Every person created male or female according to biological sex.
Individual schools write their own versions, and both the statement's wording and any related conduct expectations vary school by school.
Who signs can vary too — ask whether a school's policy covers every teacher or mainly the Bible and religion teachers.
Pastor references sit alongside the statement at schools that ask for them.
Where a school asks for one, it is asking someone who knows your church life to speak to your faith commitment — not just your classroom work.
It helps to know what the form covers before you choose the referee.
If your own beliefs or commitments sit uneasily with a school's statement, raise it directly with the hiring contact before you sign anything.
Schools differ from one another, and the conversation goes better before an offer than after.
Ask for the reference form before you ask your pastor
Do you need a teaching certificate? (ACSI and state)
There is no single national answer.
Each state writes its own rules for teachers at private schools, and a state's requirement may reach some categories of private schools and not others.
The answer for a Christian school therefore depends on the state, and on how that school is organized and whether it participates in state programs.
Where no teaching certificate is legally required, background-check and mandated-reporter rules can still apply, and an individual school may still prefer or ask for a state license.
ACSI certification is an association certificate — a private credential, not a state license.
A new teacher can earn a first ACSI certificate immediately with a bachelor's degree in any field, then complete a professional growth plan in three areas: Bible knowledge, educational studies and Christian philosophy of education.
ACSI publishes its certificate structure and requirements on its own site.
ACSI certificates run in levels.
Temporary is a 3-year certificate for teachers who do not yet meet all education, biblical and/or philosophy requirements; Standard runs 5 years, as does Professional, which requires a graduate degree.
Lifetime comes after 10 years at the Professional level and 10 years teaching in a Christian school.
ACSI offers eight K–12 certificates, from Elementary Teacher (K–8) and Secondary Teacher (7–12 subject) to Specialist Teacher, Bible Specialist and administrative certificates.
At ACSI-accredited schools, the accreditation standards let teachers hold either ACSI certification or a state certificate.
Teachers who rely only on a state license are asked to complete ACSI's Christian Philosophy of Education requirement within their first 3 years of employment, plus six Bible CEUs — six clock hours — each school year.
ACSI and Cedarville University have also launched an online Alternative Certification Pathway for people with a bachelor's degree in any field, including career changers, beginning Fall 2026.
Lutheran schools add their own structure.
Teachers already serving in Lutheran Church–Missouri Synod schools can join the Synod as commissioned ministers through colloquy.
Colloquy combines college-level coursework — six core classes plus program-specific classes, delivered online through the Concordia University System — with district endorsement and a final examination.
After that, a Concordia faculty votes to certify the candidate for call and placement.
Seventh-day Adventist schools have a denominational credential of their own.
In its 2023 certification manual, the Adventist North American Division lists six educator certificates: Basic Teaching, Standard Teaching, Professional Teaching, Administrator, Designated Subjects/Services and Conditional Teaching.
A Basic Teaching Certificate is valid three years and requires Adventist church membership, a bachelor's degree, 20 semester credits in education and 12 semester credits of religion from an Adventist college; Standard and Professional certificates are valid five years.
It is the denomination's credential, not a state license — ask the school or the denomination's education office what it requires before you apply.
Confirm the credential your school and state actually require
How hiring works
Christian school hiring runs through the schools themselves and the networks around them.
Openings surface on a school's own website and on job boards like SchoolHires.
Because a school's hiring may run through one administrator rather than an HR department, your application gets a close read — and you can expect faith fit to be weighed alongside teaching ability.
The application mirrors the school's mission.
Expect questions about your faith as well as your teaching: a personal testimony or faith statement, a response to the school's statement of faith, and pastoral or character references.
Where a school asks for a demo lesson, expect it as part of the interview stage.
The interview probes both sides too.
Alongside questions about instruction, classroom management and assessment, plan for questions on your testimony, how you would integrate scripture into your subject, and how you would handle a student or parent question about the school's doctrine.
Federal law frames this part of the process.
Title VII, the federal employment-discrimination statute, does not apply to a religious educational institution with respect to employing individuals of a particular religion to perform work connected with its activities (Section 702, 42 U.S.C. 2000e-1(a)).
A second provision (Section 703(e)(2), 42 U.S.C. 2000e-2(e)(2)) lets a school owned, supported, controlled or managed in whole or substantial part by a particular religion — or whose curriculum is directed toward propagating one — hire employees of that religion.
The First Amendment's ministerial exception reaches beyond job titles.
In Our Lady of Guadalupe School v.
Morrissey-Berru (2020), the Supreme Court barred employment-discrimination claims by two Catholic elementary school teachers whose duties included educating students in the faith, even though their titles were not "minister."
The Court's test — "what matters is what an employee does" — is why the faith duties in a Christian school job description carry weight beyond the classroom.
How any of this applies to a specific school and role is a legal question, not one this guide answers.
If you hire for a Christian school, you can also post a Christian school job on SchoolHires.
Find Christian school teacher jobs
Christian school teaching runs from elementary classroom roles through high school subject specialists, Bible teachers, and part-time and elective positions — at evangelical, Baptist, Lutheran, Adventist and classical Christian schools across the country.
Browse Christian school teacher jobs on SchoolHires to see current openings.
Listings show the school, the location and the pay where a posting includes it, so you can tell at a glance which openings are full-time or part-time and where they are.
Before you apply, reread the school's statement of faith and doctrinal standards, and ask early about certification expectations — whether the school wants ACSI certification, a state license or both.
Both conversations are worth having before you invest in the application.
