HSPT & admissions at Houston Catholic high schools
Houston's Catholic high school set has the clearest all-boys/all-girls split in Texas, and the 'best schools in Houston' forum threads usually mix in PK-8 elementary schools (St. Vincent de Paul, St. Anne, St. Michael, St. Cecilia) that are not high schools. The high-school view: Strake Jesuit (all-boys, the largest Catholic high school in Texas), St. Agnes and Duchesne (all-girls), St. Pius X (coed), Cristo Rey Jesuit (coed, work-study), and Frassati in Spring. Cristo Rey Jesuit is one of the four Texas schools with a source-reviewed HSPT record; for the others, confirm the current entrance-test policy with each admissions office. The Archdiocese of Galveston-Houston's school finder (choosecatholicschools.org) has the complete list.
Houston Catholic high schools and their admissions pages
Each school sets its own admissions and testing process. Link opens the school's own page for the current cycle.
Most Catholic high schools give the HSPT between mid-November and mid-January of 8th grade, and Houston-area schools test during the fall admission cycle. Each school posts its own date, usually by early fall, so plan prep around the earliest date on your list rather than assuming one shared sitting.
How to prepare for the HSPT in Houston
Start with the free diagnostic to establish a baseline, then build a study plan around the date your school posts. These guides cover the practical questions Houston families ask:
When to start HSPT prep
How far ahead to start, based on your test date, school list, and how much prep your child can sustain.
Best order to prep for HSPT sections
Which sections to attack first for the fastest score gains instead of random practice.
4-week HSPT study plan
A realistic one-month plan for families starting late but still wanting to move the score.
How should my 8th grader prepare for the HSPT?
When to start, what to practice, how much daily work, and how to keep it sustainable.
HSPT scholarships by city
Where school-list width, selectivity, and tuition make scholarship research matter most.
What is a good HSPT score?
What different percentile bands actually mean to a family, admissions-wise.
Houston Catholic high schools sit in the Archdiocese of Galveston-Houston, which runs the choosecatholicschools.org finder covering the full Pre-K-12 picture. Ask each school whether one HSPT sitting can be shared across the schools you are applying to, and whether the test is used for admission only or also for placement and scholarship consideration.
For the fall admission cycle, Houston families typically research schools in the spring of 7th grade, visit during 8th-grade fall, and test between mid-November and mid-January. Application, financial-aid, and scholarship deadlines differ by school, so collect them in one place early and treat them as planning inputs, not reasons to choose one school over another.
Planning a Catholic high school application
Entrance-test rules are set by the school or diocese and can differ even within the same city. Check each school’s admissions site before registering. If a school is confirmed in our HSPT guide, its directory page links directly to the current admissions and preparation notes.
- Confirm whether each school requires the HSPT or another entrance test for the current cycle.
- Record application, transcript, recommendation, financial-aid, and scholarship deadlines separately.
- Ask whether one HSPT sitting can be shared with other schools in the same diocese.
- Compare the daily commute as well as tuition, aid, academic programs, and school size.
