What is the Admissions Process for Independent Schools in St. Louis?

Admissions Timeline

Independent Schools of St. Louis (ISSL) member schools follow a shared admissions timeline, giving families a more consistent timeline as they explore their options.

Here is the timeline you can expect when exploring schools for the following academic year:

Fall is for exploring.

Begin researching schools that may meet your child's needs. Attend open houses, plan campus visits, and request admissions and financial aid information. (You can find details about timing and location for all ISSL member open houses through our public calendar.)

You can also start applications and schedule any required interviews or student visits during this time.

Winter is for applying.

Many applications and financial aid forms are due in December or January. Make sure each school has received any required transcripts, references, test scores, or other supporting materials.

Spring is for finalizing decisions.

Admissions decisions generally begin in early February for high school and mid March for all other grades, with financial aid decisions arriving around the same time. If your child receives multiple acceptances, use the decision period to revisit what you learned and decide which school makes the most sense for your family.

Summer is for joining the community.

After enrolling, summer may include opportunities for new students and parents to get acquainted with the school community before the academic year begins.

Admissions Deadline

While ISSL member schools share a general admissions timeline, the exact application deadlines can vary by school. Most application deadlines fall in December and January; financial aid applications are generally due in December, January, and February.

Application Requirements

Every school has its own application requirements. Depending on the school and your child's grade level, you may need to supplement an application with prior school records, teacher recommendations, questionnaires, or other supporting materials.

Applicant Evaluation

Independent schools want to understand the student behind the application. So, when an application asks you to describe your child, focus on helping the school understand who they are. Share useful context about how your child learns, what interests them, and what you hope to find in their next school. You are not trying to write the "perfect" answer. You are helping the school get to know your child.

An acceptance matters, but fit matters, too.

Financial Aid

For many families, affordability is part of the school decision from the beginning. Do not be afraid to ask about it!

Tuition and financial aid opportunities vary among independent schools. If your family plans to apply for aid, request information early (we recommend in the fall) and pay close attention to financial aid deadlines.*

Preparing for an Interview or Visit with a Private School

A campus visit can turn a school from a name on your list into a place you can actually picture your child attending.

Here's what we recommend when preparing for a visit or interview with a school:

  1. Before your visit: Write down the questions that matter most to your family. Maybe you want to understand how teachers get to know individual students. Maybe your child wants to see what a normal school day feels like. Ask about the things that will help you make a decision, not simply the questions you think an admissions team expects to hear.
  2. While you're there: Look beyond the tour route. Pay attention to the classroom atmosphere and how people interact. When appropriate, give your child a chance to ask questions, too. Most importantly, be yourself. A school visit is your opportunity to learn whether the community could be a good match for your child, not a test your family needs to "pass."
  3. After the visit: If appropriate, send a thank-you letter or email to the person you spoke with. Then, jot down your thoughts: what you liked, what you have more questions about, and if the vibes felt "right."

Finding the Right Private School

Families face increasing pressure to find the "best" school to set their child up for success. As those who have been in the St. Louis independent school scene since the 70s, we'll let you in on a secret: There is no best school. There's just the school that fits your child.

And ISSL is here to help you find that fit.

ISSL connects families with a curated group of dozens of independent schools across the St. Louis region, giving you a more manageable place to explore your options. We do not choose a school for you or favor one member school over another. We give you a trusted starting point, and your family chooses the path that makes sense.

Find a School

It depends on the school. Some ISSL member schools request teacher recommendations or other references as part of the application.

If your child needs specific learning support, talk with the school about those needs during the admissions process. The conversation can help your family understand what support the school offers and whether its learning environment may be a good fit for your child.

The timeline for ISSL member schools typically takes several months. The process of researching schools and attending open houses starts in the fall of the preceding school year, with application deadlines typically running through December and January, although the exact date will vary by school. Acceptance letters typically arrive in early February and mid-March, depending on the grade level.

Questions you may find helpful during a school tour include:

  • What learning support services do you offer?
  • What STEM opportunities are available?
  • Are there extracurricular opportunities?
  • What qualifications and experience do the teachers have?

When deciding on the right private school, it helps to start at the beginning, with your child. Think about how they learn, what kind of environment helps them feel comfortable, and what you want their school experience to look like. Then, use school visits to see how those priorities line up with each school's approach.
