You can:

*Our online application is often updated between June and September, please do not begin it until October 1st.


St. Mark's also accepts the Gateway to Prep Schools, Standard Application Online (SAO), and The Association of Boarding Schools (TABS) common applications.
Please note, students who choose to apply through these common applications are required to complete St. Mark's application supplement and fulfill all of the recommendation requirements listed in sections 4 and 5 below.

Optional Supplement: EMA's Character Skills Snapshot (CSS)

St. Mark's is more than just a place where your child will learn math, English, and science. Certainly the reason you're seeking to enroll your child here is because you're interested in an education that focuses on instilling character values and encouraging personal growth. Similarly, we know that your child is much more than grades and test scores. That's why we're asking your child to take The Character Skills Snapshot as part of their application. It will give us richer holisitc information about your child, and show us areas where our community can help them grow, thrive, and shine. Visit the Enrollment Management Association (EMA) to learn more.

4. Recommendation Forms

St. Mark's requires three teacher recommendations: English, Math, and Foreign Language. If you are applying through St. Mark's online application portal, you should send an email invitation from the application portal to your teachers to complete the recommendations online. Ask them to complete the forms after November 1 and return them to our office by January 31. If you are not enrolled in a foreign language course, or if English is your foreign language, please submit the science recommendation instead. The Special Interest Recommendation form is optional. St. Mark’s accepts the Common Recommendation form.

Please note that you are still required to submit all three recommendation forms if you apply through Gateway, TABS, or SSAT (SAO).

Portfolio Submission

If you have a well developed talent in the creative or performing arts, you may submit samples of your work for review by St. Mark's art, theater and music faculty. You may also submit athletic videos for our coaches to view. St. Mark's accepts athletic videos and art submissions via Slideroom. Please review the detailed submission instructions on the Slideroom website. If you elect not to submit materials via Slideroom, you may include with your application a printed art portfolio or athletic resume that lists your training and experience, repertoire or roles performed and honors received. For network security purposes, we cannot accept submissions via USB drives, CD, DVD, or email.

Online Checklist Information for GTP and SAO Applicants

As our office processes applications submitted through Gateway to Prep (GTP) and Standard Application Online (SAO), we will begin to send each family an email with an invitation link to their St. Mark's online checklist account.

*If you applied through St. Mark's online application, you already have access to your online checklist and no further action is required.

Important to know for checklist account creation:
  • Please wait until you receive our email invitation link to create your checklist account. Please do not create a St. Mark's application account on your own as this will slow down the processing of your application.
  • The invitation email will have the subject: St. Mark's School: Confirm your email
  • Invitations will be sent to one parent email.
  • Remember to check spam folders and add @stmarksschool.org to your safe senders list.
Important to know for checklist tracking:
  • Please remember that our application is made up of multiple GTP and SAO components (Candidate Profile/Bio, Parent Statement, Student Statement, SM Supplement), if we are missing one of those four components, your "application" will not yet be marked complete in your St. Mark's online checklist.
  • St. Mark's requires two years of transcripts plus your current grade report. If your school only uploaded one of these three items, this requirement may be marked as complete on GTP or SAO, but it will NOT be marked complete on St. Mark's checklist until we have received all three from your school.
  • If you see that a recommendation or item is marked incomplete, and you believe it has been submitted, please contact our office. Please remember however that our checklist is not "real-time" and allow 48 business hours for processing.
Letters of decision will be emailed on March 10, and your reply is expected by April 10. Students who are accepted will be invited to Re-Visit campus during select dates in early April.
