Admissions Process & Key Events
Mater Dei’s admissions cycle generally follows a priority-deadline structure: applications open in the fall, the High School Placement Test (HSPT) is administered on campus in January, and priority-group decisions are typically released in February or March. Applications submitted after the priority deadline are evaluated on a rolling basis as space allows. Families should confirm exact dates for the current cycle directly with the admissions office, since deadlines can shift year to year.

What Makes Mater Dei’s Admissions Process Unique?
Submitting the online admissions application automatically registers incoming 9th graders for the on-campus HSPT, so families don’t need a separate testing registration step. General 9th-grade applicants are evaluated primarily on transcripts, HSPT results, and a required academic recommendation from their current Principal or Vice Principal, rather than a formal interview. Transfer students and international applicants, by contrast, complete a required one-on-one interview as part of their process.
Top Tips for Applying
- Submit your application early: it doubles as your HSPT registration, and the exam is only offered on specific dates.
- Make sure your current Principal or Vice Principal is prepared to submit the required Academic Recommendation directly.
- If applying as a transfer or international student, prepare specifically for the required one-on-one interview.
Best Practices for Families
- Attend an Open House to learn about the school’s STEAM emphasis and Academy of Science firsthand.
- International applicants should start early on certified translated transcripts and the two required teacher recommendation letters.
- Confirm current-cycle deadlines directly with the admissions office, since specific dates can shift from year to year.
What the Mater Dei Application Requires
To apply to Mater Dei Catholic High School, you will need to submit the following:
-
01Testing Policy
The High School Placement Test (HSPT) is required for all incoming 9th-grade applicants, administered on campus in January with makeup dates in the spring. A writing assessment is included as part of the HSPT testing battery.
-
02Recommendations
An Academic Recommendation from the applicant’s current Principal or Vice Principal is required. An optional Character Recommendation (from a coach, clergy member, business professional, or non-family mentor) may also be submitted. International applicants require two teacher letters of recommendation instead.
-
03Transcripts
Official 7th- and 8th-grade report cards or transcripts are required. International applicants must submit official transcripts in the original language along with certified English translations.
-
04Interviews
General 9th-grade applicants are not required to interview; the process focuses on transcripts, HSPT scores, and the Principal or Vice Principal recommendation instead. Transfer students and international applicants complete a required one-on-one interview prior to admission.
“As international applicants, honestly, the HSPT felt like this huge unknown until Cardinal Education stepped in. They sat down with us, showed my child what the test actually looked like, and just kept working with her until she felt ready. Grateful that she got into Mater Dei. Thank you for the support along the way!”— International Parent From Mater Dei
