Accommodations and testing setup at Mount Saint Joseph High School
If your child has an IEP, 504 plan, ADHD, dyslexia, anxiety, or another documented need, ask Mount Saint Joseph High School’s admissions office how HSPT accommodations are approved before registration closes. Start with the HSPT accommodations guide, then confirm whether the school handles extended time, separate room or small group testing, ADHD accommodations, dyslexia accommodations, and documentation through the school or the diocese.
How to prepare for the Mount Saint Joseph High School entrance exam
Mount Saint Joseph High School uses the HSPT — a five-section, ~300-question exam covering verbal skills, quantitative skills, reading, math, and language (see What is the HSPT?). Start with a free HSPT diagnostic, then focus on three things:
- Start 8–12 weeks before the exam date. Short daily practice builds the speed the HSPT’s pacing demands.
- Practice the unfamiliar question types first. Analogies, number series, and logic items aren’t taught in most middle schools — they’re the fastest points to gain.
- Treat the first sitting as the only sitting. Most schools accept one attempt, and at many schools the score also drives merit scholarships.

Common questions
What entrance exam does Mount Saint Joseph High School require?
Mount Saint Joseph High School admits through the High School Placement Test (HSPT), a five-section exam covering verbal skills, quantitative skills, reading, mathematics, and language, taken in the fall or winter of 8th grade.
When is the Mount Saint Joseph High School entrance exam?
The school's website listed November 14, 2026 or November 21, 2026 when we last checked (2026-10-17). Dates change every admissions cycle, so confirm with the admissions office before planning around them.
How should my child prepare for the Mount Saint Joseph High School entrance exam?
Start 8–12 weeks before the exam date with short daily practice, and focus first on question types middle schools don't teach — analogies, number series, and logic problems. Most schools accept one sitting, so the first attempt counts.
How do I register for the HSPT at Mount Saint Joseph High School?
HSPT registration is generally handled through Mount Saint Joseph High School's admissions process rather than through a national family registration site. Use the school's current checklist and confirm the test location, arrival time, fee, and required identification directly.
How long is the Mount Saint Joseph High School HSPT?
The standard HSPT has about 298 questions across five sections and usually takes about two and a half hours, not including check-in or breaks. Ask Mount Saint Joseph High School for its test-day arrival and dismissal window because local administration details can differ.
Can students use a calculator on the HSPT at Mount Saint Joseph High School?
The standard HSPT mathematics and quantitative sections are designed to be completed without a calculator. Families should still read Mount Saint Joseph High School's current test-day instructions so the student brings only permitted materials.
Does Mount Saint Joseph High School offer HSPT accommodations?
Students with an IEP, 504 plan, ADHD, dyslexia, anxiety, or another documented need should contact Mount Saint Joseph High School before registration closes. Ask what documentation is required and whether extended time, small-group, separate-room, or other arrangements are available.
What else does Mount Saint Joseph High School require besides the HSPT?
Mount Saint Joseph High School also lists recommendations, interview, visit or event, and shadow day as part of the admissions process. Use the school's checklist early, because these steps often move on the same compressed fall timeline as testing.
