Registration, Test-Day Logistics & the Optional Subtest
Key Takeaways
- HSPT registration is handled by the individual Catholic high school or diocese, never directly with Scholastic Testing Service, and the fee (commonly $25-$50) is set by the administering school.
- Schools may add one optional 40-question subtest - Science, Mechanical Aptitude, or Catholic Religion - which is reported separately and is never folded into the five-subtest battery scores.
- Scholastic Testing Service advises taking the HSPT once; STS states that when a student tests more than once, the lower score is the one used.
- Testing runs about three hours on site even though only 141 minutes are scored testing time, because administration, instructions, and two short breaks sit between the subtests.
Registration, Test-Day Logistics & the Optional Subtest
Content knowledge is only half of an HSPT score. The other half is arriving at the right building, on the right morning, with the right materials, having already decided how you will handle the optional subtest and the breaks. Every one of those details is controlled by the administering school or diocese rather than by Scholastic Testing Service (STS), which is why two students in different cities can have very different HSPT experiences on the same date.
How Registration Actually Works
You do not register with STS. STS publishes, ships, scores, and norms the test, but the point of contact for a family is always the Catholic high school (or the diocesan office that runs a common test day).
| Step | Who Handles It | What Families Do |
|---|---|---|
| 1. Choose a test site | The high school or diocese | Pick the school where you will physically sit the exam - usually your first-choice school |
| 2. Register & pay | The high school or diocese | Complete the school's registration form; the fee is commonly $25-$50 and is set locally, not by STS |
| 3. Designate score recipients | The student, on test day | List the schools that should receive your score report |
| 4. Sit the exam | The school proctors it | One sitting, five subtests, roughly three hours on site |
| 5. Receive results | STS scores; the school releases | Score reports reach families through the school, not by direct mail from STS |
Some dioceses run a single coordinated exam day for every participating high school. In northern New Jersey, for example, the Cooperative Admissions Examination Program (COOP) administers the HSPT on one common Friday for the Archdiocese of Newark and the Diocese of Paterson, and a student's single score is distributed to the schools they designate. Other regions let each school schedule its own dates, so calendars differ from diocese to diocese.
Do not confuse the HSPT with TACHS. The Test for Admission into Catholic High Schools (TACHS) is a different exam used by the Archdiocese of New York and the Diocese of Brooklyn/Queens. Preparing for one does not prepare you for the other's format.
The Test-Day Timeline
Only 141 minutes are scored testing time, but plan for roughly three hours on site. The gap is administration: seating, answer-sheet coding, spoken instructions before each subtest, and two short breaks.
| Block | Typical Duration | What Happens |
|---|---|---|
| Check-in & seating | 15-30 min | Roster check, room assignment, answer sheets distributed |
| Answer-sheet coding | 10-20 min | Bubbling name, birth date, student ID, and the schools to receive scores |
| Verbal Skills | 16 min | Subtest 1 |
| Quantitative Skills | 30 min | Subtest 2 |
| Break | ~5-10 min | Proctor-controlled |
| Reading | 25 min | Subtest 3 |
| Mathematics | 45 min | Subtest 4 |
| Break | ~5-10 min | Proctor-controlled |
| Language | 25 min | Subtest 5 |
| Optional subtest | ~20-30 min | Only if the school orders one |
Proctors announce the halfway point of each subtest. Treat that announcement as your primary pacing checkpoint: on Verbal Skills, the eight-minute call should find you at roughly question 30; on Mathematics, the 22-minute call should find you near question 32.
What to Bring - and What Is Banned
- Bring: several sharpened No. 2 pencils with erasers, your admission ticket or confirmation if the school issued one, and a watch only if the school permits it (many do not allow any watch with an alarm or a screen).
- Banned: calculators of every type, phones, smart watches, tablets, dictionaries, and separate scratch paper. All computation happens mentally or in the margins of the test booklet.
- Not needed: highlighters and colored pens. The answer sheet is optically scanned; only No. 2 pencil marks read reliably.
The no-calculator rule is absolute and applies to both math subtests. That is a design choice, not an oversight: HSPT items are built around friendly numbers, memorized facts, and estimation, so a student who has drilled mental arithmetic is not disadvantaged by the ban.
The Optional Sixth Subtest
Beyond the five required subtests, a school may order one optional 40-question test in:
- Science
- Mechanical Aptitude
- Catholic Religion
Three facts matter for your planning:
- It is optional at the school's discretion. Many schools order none, so most students never see it.
- It does not enter the battery. The optional score is reported separately with its own topic-by-topic breakdown; it is excluded from the Verbal, Quantitative, Reading, Mathematics, and Language standard scores and from the Total Cognitive, Total Basic, and Total Battery composites.
- You will be told in advance. If your school orders one, that appears in the registration materials, so ask rather than assume.
Accommodations
Students with documented learning differences or physical disabilities may receive accommodations such as extended time, large-print booklets, or small-group administration. Requests go through the admissions office of the administering school, with current documentation, before the registration deadline. Accommodations are not granted on test day, and a student who arrives expecting untested extra time will simply be timed normally.
Taking the HSPT More Than Once
STS advises that the HSPT be taken one time. Whether a retake is even permitted is decided by the diocese or the school, and is usually reserved for documented extenuating circumstances such as illness on test day.
The rule that surprises families: STS states that when a student tests more than once, the lower score is the one used. A retake therefore carries real downside risk - it cannot only help you. Treat your first sitting as the score that counts, and put the preparation in beforehand.
After the Test: Who Sees Your Scores
Scores are released to the schools the student designated on the answer sheet, and families normally receive the Student Score Report through the school rather than from STS. Schools then apply their own cutoffs for admission, honors placement, and merit scholarships - the same standard score can mean different things at two schools in the same diocese, because each institution sets its own thresholds.
