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)

Transfer Students: Now Accepting Applications

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, please call St. Thomas Hich School for future dates. Applicants for 11th and 12th grades must submit their 10th and 11th grade PSAT and SAT results.
