How to Apply

To ensure that an applicant is able to handle St. Thomas' challenging college preparatory curriculum, selective admissions decisions are based on:

  • Compatibility with the St. Thomas Community, including priority of choice in selecting STH
  • Results of the High School Placement Test
  • Overall junior high record (academic, behavioral and attendance)
  • Recommendations of junior high principal and teachers
  • Quality of application (essay, involvement in school activities)
Online Application & Fee

Click here to access the Online Admission Application

The deadline for the online application (just the application, not the supplemental material) is January 15, 2015. However, we request students and their parents complete the application as early as they are able. While parents may complete the first few pages of the application, the student applicant must complete the final page which includes the essay and activities. The $75 application fee may also be paid online, by mail or by visiting St. Thomas. We must receive the application and fee by the deadline in order to review a candidate for admission.

Transcripts & Recommendations

Download a copy of the following forms and submit them to your school after December 1. Please do not request transcripts until after the fall semester has ended.   We must receive these completed documents directly from your son's current school by the January 15 deadline, or if your school ends its fall semester in January, then within one week after the semester has ended. We must receive these completed documents directly from your son's current school by the January 15 deadline.

Transfer Students

The application process for transfers is similar to that for freshmen with a few exceptions. The first is that an applicant may substitute the PSAT for the HSPT. The second is that all applicants for 10th, 11th and 12th grade are personally interviewed when their application file is complete. Although the timeline for transfer students' applications does not follow the same deadlines as those for freshmen, we strongly recommend that transfer applicants complete their files as soon as is feasible. Available spaces in 10th, 11th and 12th grade classes are usually filled by the beginning of May.

Applicants for 10th grade who have not taken the HSPT must do so. Applicants for 11th and 12th grades must submit their 10th and 11th grade PSAT and SAT results.

Open House 2014 

Open House is for students of any age but especially for those in 6th, 7th and 8th grades. Each year our Open House allows prospective students and their families to tour the school, meet with faculty, coaches, administration and current students and their families. Please don't be late. The program begins at 1 p.m. on Sunday, November 9th in Cemo Auditorium of the Moran Fine Arts Center. After a presentation, families will tour the school. (Hint: tours are dismissed from the front of the auditorium so sit as close to the front as you are able.) At the end of the tours, our community will be gathered in the gymnasium, where prospective families may ask specific questions that are relevant to their sons, as well as enjoy refreshments by our Mothers' Club
