A division head is the school leader who runs one division of a private school — the lower school, the middle school or the upper school — under the head of school.
At schools large enough to split grades into divisions, the division head does the work a public-school principal does at the building level: supervising teachers, owning the division's academic program and student life, and reporting to the head of school.
A school that keeps one leader for every grade folds the role into a single principal.
What is a division head?
A division head is the leader who runs one division of a private school — the lower school, the middle school or the upper school.
Independent schools that split their grades into divisions give each division a head who leads it day to day.
A school that keeps one leader for every grade calls that person the principal or the head of school.
The title changes with the school.
A posting may say division head, division director, head of the lower school, head of the middle school or upper school head — read for the work, which is the building-level leadership of a private school's division.
In a division structure, the division head sits between the classroom and the head of school's office.
Deans of students, department chairs and teachers report to the division head, and the division head reports to the head of school.
The rungs around a division headship on this ladder are dean and assistant principal roles below it and the head of school above it.
Scale gives the job market its size.
NCES, the federal education statistics agency, counted 24,040 private school principals (head count, full- and part-time) in 2020-21, against 91,900 public school principals.
In NCES tables the public figure includes charter schools, and the private figure covers all private schools: Catholic, other religious and nonsectarian.
What the role carries grows out of that structure.
A division head in a three-division campus owns a slice of the program; a principal in a one-building school owns all of it.
The duties travel with the structure, not the label.
What do lower, middle and upper school heads do?
The core of the job is the same from division to division: an academic program, a teaching staff and a group of students.
The work is hiring and evaluating teachers, building the schedule, setting and enforcing discipline, meeting parents, handling crises, and representing the division to the head of school and, when asked, to the board of trustees.
The division changes the emphasis more than the job.
A lower school head lives in early literacy, homeroom culture and parent communication.
A middle school head manages adolescence: advisory programs, social conflict and the transitions in and out of the division.
An upper school head works closest to graduation — transcripts, department chairs, academic integrity, discipline with college consequences, and coordination with the college counseling office.
Faith and pedagogy schools add a mission layer.
In a Catholic, Christian or Jewish day school, the school's religious identity shapes curriculum and hiring, and the division head's job carries that mission with it.
In a Montessori, classical or Waldorf school, the divisions are organized around the method, so program decisions are pedagogy decisions too.
Pay tracks the division.
At NAIS member schools in 2025-26, median salaries were $153,296 for an upper school head, $143,216 for a middle school head and $140,000 for a lower school head.
NAIS publishes medians for its member schools only — a reporting slice of independent schools — not averages for private schools as a whole.
Is a division head the same as a principal?
Mostly, yes — the difference is the size of the territory.
A private school that keeps every grade under one leader calls that person the principal, the headmaster or the head of school.
A school split into divisions gives each division a head who carries the principal's work for that division.
Private school principal and division head name the same job market from two angles.
The head of school is the real boundary.
The head answers to the board of trustees for the whole school: budget, strategy, the senior team, and the school's standing with its accreditor and, in faith schools, its diocese or church.
The division head answers to the head for one division.
The public district comparison sharpens the picture.
District principals run buildings inside a superintendent's system, and the job carries a state credential behind it: BLS states that most states require public school principals to be licensed as school administrators.
The same BLS page does not describe a license requirement for private school principals — private schools set their own expectations.
BLS treats principals as one occupation across all school types.
Its Occupational Outlook Handbook reports a 2025 median pay of $105,870 per year for elementary, middle and high school principals, with about 343,800 jobs and little or no change (0%) projected for 2025-35.
About 21% of principal jobs in 2025 were in privately owned elementary and secondary schools, where the May 2025 median wage was $98,020 against $107,860 in local-government schools.
Label those numbers before using them.
BLS has no private-school or charter-school occupation code; the figures cover public district, charter and private schools together — read them as principal-occupation data, not a division-head pay table.
The privately owned line is an ownership cut, not a private-school pay table.
How do you become a division head?
The path into a division headship runs through classrooms.
In NCES's 2020-21 survey, private school principals had taught an average of 14.8 years before becoming principals, against 11.9 years for public school principals.
The spread is wide: 14.4% of private school principals had taught three or fewer years before becoming principals, against 3.4% of public school principals, while 31.0% of private principals had taught 20 or more years first, against 12.1%.
Degrees work differently in the private sector.
BLS describes the typical entry to the principals occupation as a master's degree in education leadership or administration plus several years of teaching experience — a description of the occupation across all school types.
Among private school principals in 2020-21, 28.2% had a bachelor's degree or less as their highest degree, against 1.4% at traditional public schools and 8.1% at charter schools; 9.3% of private principals held a doctorate or first-professional degree.
What stands in for the license is a record.
The record to build is leadership of other adults: department chair, grade-level lead, dean of students and curriculum committee chair are the roles to point to.
The posting names what the school wants; the interview tests whether you can run a division on day one.
Teach, and teach visibly
Build the classroom record the school will point to. Take on the grade level, subject or cohort that other teachers get sent to observe.Lead adults close to the classroom
Department chair, grade-level lead, dean of students, advisory coordinator: each puts you in charge of other teachers' work — the experience a division-head file reads on.Add the graduate piece deliberately
Graduate coursework in education leadership strengthens a file — BLS describes a master's degree as the typical entry to the principals occupation — and a school or accreditor can add requirements of its own. How much any private school weighs it shows up in the posting — read before you enroll.Own a division-wide project
A schedule rebuild, a curriculum review, a new advisory program: the work a division head owns is work you should have already done under someone else's signature.Apply where the structure fits
Lower, middle and upper school headships reward different instincts, and a one-principal K-12 school is a different job than a three-division campus. Match your record to the division, not just the title.
Career information, not legal advice: requirements vary by school, state, accreditor and diocese. Confirm with the school and, where one applies, the body that sets its rules.
Requirements are set school by school
Where do Catholic and Christian school principals fit?
Catholic and Christian schools run the principal job through their own structures.
In a diocesan system, the diocese's school office sits over its schools; in a parish or church-run school, the pastor or church board sits in the structure; and a Catholic high school can split leadership between a president and a principal.
The teaching-to-division-head ladder runs inside these structures, not instead of them — ask who the role answers to before you take the job.
The workforce behind those roles: NCEA, the Catholic schools' association, reports 151,513 full-time-equivalent professional staff in Catholic schools in 2025-26, of whom 92.8% were lay professionals and 2.5% religious sisters, brothers and clergy, as the association publishes the shares.
Pay splits by school type, and the numbers date quickly.
In NCES's 2020-21 survey, private school principals averaged $79,200 at Catholic schools and $63,000 at other religious schools, against $106,300 at nonsectarian schools.
The all-private average was $78,600, against $106,500 at traditional public schools in the same survey — 2020-21 dollars, not current pay.
Faith-school associations also run credentials of their own.
ACSI, the Association of Christian Schools International, runs its own teacher-administrator credentialing.
Its five-year certificate tiers are Standard and Professional, with Professional requiring a graduate degree; a Lifetime certificate follows 10 years at the Professional level.
A three-year provisional-type certificate covers educators still completing education, biblical studies or philosophy requirements.
Where a school answers to a diocese, check what the diocese expects of its leaders as well.
For the leader, the faith-school division head job is the independent-school version with a mission overlay: the same building-level work, carried out inside the school's religious identity.
Find division head and principal jobs
Division head and principal openings live where the structures live: three-division independent day schools, single-campus Catholic and Christian schools, boarding schools, and charter schools and networks filling principal seats.
Read postings for structure before you apply — the grades, the division, the reporting line and the size of the school change the job more than the title does.
Build your file around the job: a teaching record with length on it, leadership of other adults, curriculum judgment, parent communication, and fit with the mission.
Shape the file to the division you want; a lower school application reads differently from an upper school one.
Current division head and principal openings are listed on SchoolHires as private, independent, faith-based and charter schools post them.
Browse what is open, and watch for the division structure that matches your record.
