NYC private and independent school admissions, explained

Private and independent schools run on a system entirely their own, no central portal, no citywide match, and a calendar that starts roughly a year before your child would walk in the door. The mechanics feel different from the public side because they are: you apply to each school directly, each school decides for itself, and a shared calendar keeps the whole thing orderly. This guide walks through how that process works, neutrally, there is no default sector here, only different systems that fit different families. For a side-by-side of private schools against DOE, charter, and parochial options, see the sector comparison linked below.

How it works in 60 seconds

• Private / independent schools are tuition-based (most offer need-based financial aid) and run by their own boards.
• They sit entirely outside the DOE's MySchools portal, there is no citywide private match.
• You apply to each school directly, there is no centralized application. Many schools collect applications through a common platform such as Ravenna.
• The cycle runs about a year ahead: tour in the fall, complete files by around early January, and ISAAGNY schools release decisions on a shared date in late winter (commonly February).
• ISAAGNY, the area's independent-school admissions association, is a membership group that coordinates a shared calendar and shared forms, not a regulator and not a single application.

The ISAAGNY calendar and process

The Independent Schools Admissions Association of Greater New York (ISAAGNY) is the one organization that makes the private-school landscape feel coordinated, so it's worth understanding exactly what it is, and isn't. ISAAGNY is a membership association of independent schools in and around New York City. Its member schools agree to a common set of Principles of Good Practice and to a shared Notification and Reply calendar, so that families get decisions on a common timeline and can weigh their options with all the information in hand. Many member schools also use shared forms, for example, common recommendation forms, to streamline the process.

What ISAAGNY is not is a centralized application or a regulator. It does not run a single ranked match the way MySchools does, and it does not admit students. Each school coordinates its own admissions events and makes its own decisions, ISAAGNY simply aligns the calendar and the standards around them. So you still apply to each school individually, often through a common platform such as Ravenna, which is a convenience for submitting materials, not a single application that schools rank.

The rhythm runs roughly a year ahead of the start date. In broad strokes, and hedging on the specifics because they shift each cycle and vary by school:

• Prior fall (sometimes late spring before), schools hold tours, open houses, and information sessions; you research and visit.
• Fall, applications open and the first parts come due; some schools open as early as late summer.
• Around early January, application files are typically completed (essays, recommendations, transcripts, and any testing all in).
• Late winter, ISAAGNY member schools send decisions on a shared notification date (commonly in February), with a common reply deadline a few weeks later.

A completed application usually pulls together several pieces: a parent statement or questionnaire, the student's own work or essay (where age-appropriate), teacher recommendations, an interview or visit, for the youngest applicants this is often a playdate or group observation rather than a formal interview, and testing where the school requires it. Confirm the exact deadlines and the current notification date on each school's page and on ISAAGNY's calendar every year; do not rely on last cycle's dates.

Testing by entry point

Whether your child sits for a standardized admissions test depends on the entry point and the specific school, not every school tests, and the test used changes as children get older. The ERB (Educational Records Bureau) is the organization behind the main admissions tests families encounter.

• Kindergarten, far fewer schools require a standardized test at this age. Where one is used, it has historically been an ERB-administered early-learner assessment such as the AABL (Admission Assessment for Beginning Learners); but many schools instead rely on an on-site visit or play-based observation of the child. Requirements here vary a lot by school and have changed over the years, so check each school directly.
• Older entry points (roughly grades 2 and up), many schools use the ISEE (Independent School Entrance Exam), administered by the ERB, and some accept the SSAT instead. The ISEE comes in levels keyed to the grade a child is applying to: a Primary level for the younger applicants (about grades 2–4), a Lower level (about grades 5–6), a Middle level (about grades 7–8), and an Upper level (about grades 9–12).

Treat the level-to-grade mapping above as a guide, not a guarantee, the test maker sets the official rules, and individual schools decide which test (if any) they require and accept. The single safe move is to read each school's stated testing requirement for your child's entry grade.

Age cutoffs and redshirting

Here's a detail that surprises families who assume the public cutoff applies everywhere: private and independent kindergarten cutoffs are commonly earlier than the public one. NYC public schools admit children who turn five by December 31 of the entry year. Many independent schools use an earlier cutoff, often around September 1, and sometimes earlier still.

The practical consequence: a child with a fall birthday who is eligible for public Kindergarten that year may be considered too young for private Kindergarten the same year, and would apply a year later (or to the younger class). This is also why redshirting, intentionally starting a child a year later than the earliest eligible age, comes up so often on the private side. Cutoffs vary by school, though, and some independent schools do follow the December 31 public guideline, so verify the cutoff with each school you're considering rather than assuming.

Cost and financial aid

Private and independent school tuition varies widely from school to school, and that sticker price is not the whole story. Most independent schools offer need-based financial aid, awarded on a family's demonstrated financial need, and it can meaningfully change what a family actually pays.

Financial aid is a separate application from admissions, usually filed through a third-party vendor that estimates what a family can contribute, common ones include Clarity and SSS (School and Student Services). You file once with the vendor and the schools draw on it. The most important thing to know is a mindset: don't rule a school out on its published tuition. If aid might apply to you, ask every school how its aid works and apply, the only way to know what a school will cost your family is to go through its aid process.

A note on our data

One honest caveat, so you read this site the right way. We cover the private process fully, and we carry less per-school data on private and independent schools than we do on DOE and charter schools. That is purely a data-availability issue: private schools rarely publish the consistent standardized metrics that the public sectors report. It is not a sign that we favor public schools. Where the data gap shows, we say so plainly rather than papering over it, and we still help you run the private process alongside the public ones.

Common questions

Is there one central application for NYC private schools, like MySchools for the DOE? No. There is no centralized private-school application. ISAAGNY, the area's independent-school admissions association, is a membership group that coordinates a shared notification and reply calendar and shared forms so the process is orderly and fair, but you still apply to each school on its own, and each school makes its own decision. Many schools collect applications through a common platform such as Ravenna, which is a convenience, not a single ranked match.

When does the private-school process happen? Roughly a year ahead. Families tour and research in the fall before the intended start year, applications open in the fall (some events as early as the prior spring), files are typically completed by around early January, and ISAAGNY schools send decisions on a shared date in late winter, commonly February, with a reply deadline a few weeks later. Confirm the exact dates each cycle, since they shift year to year.

Does my child have to take a test to apply? It depends on the entry point and the school. The ERB administers the main admissions tests, at older entry points many schools use the ISEE (some accept the SSAT), while at Kindergarten far fewer schools require a standardized test and many rely on an on-site visit or play-based assessment instead. Always check each school's stated requirements.

Is private school out of reach if we can't pay full tuition? Not necessarily. Tuition varies widely, and most independent schools offer need-based financial aid, applied for separately, often through a vendor such as Clarity or SSS. Aid is awarded on financial need, so don't rule a school out on its sticker price; ask every school about aid and apply if you might qualify.
