The HSPT score Notre Dame Prep Scottsdale applicants need is one of the most searched — and least clearly answered — questions in Phoenix Catholic school admissions. I've seen students walk into the December exam without a real target. That's a problem, because your child's HSPT score doesn't just determine admission. It drives freshman course-track placement and scholarship eligibility too. This post gives you the percentile benchmarks, the timeline, and a realistic prep plan so your child walks in on test day with a specific number to aim for.

What HSPT Percentile Is Competitive for Notre Dame Prep Scottsdale Admission?
NDP does not publish a minimum cutoff score. The school's acceptance rate is not publicly reported — the roughly 80% figure you'll sometimes see on forums is a community estimate, not an official NDP number. What that estimate tells us is that NDP is selective but not exclusionary. Most applicants who submit a complete, thoughtful file are admitted. Scores still matter — they just don't work in isolation.
Based on community-observed data from Diocese of Phoenix Catholic school admissions, here are the benchmarks families use to set prep targets. These are estimates, not official NDP policy — always confirm current thresholds directly with the NDP Admissions Office at ndpsaints.org:
- 75th national percentile or above on the Battery Composite: well-positioned for admission
- 85th percentile or above on the Total Cognitive Skills Composite: competitive for advanced track placement and merit scholarship consideration
- Below 50th percentile: admission is possible, but the interview, grades, and recommendation letters carry significantly more weight
The Battery Composite combines all five HSPT sections. The Total Cognitive Skills Composite combines only Verbal Skills and Quantitative Skills. Both numbers appear on every score report. Know both when results arrive.
I always tell families: set your prep goal at the 85th percentile, not the 75th. Aiming for the floor leaves no room for a rough test morning.
How NDP Uses HSPT Scores for Course-Track Placement: Thomas Aquinas Program vs. Gonzaga Program
This is the part most HSPT prep guides skip entirely — and it's the part that affects your child's entire high school experience, not just one admissions decision.
NDP uses HSPT scores to place incoming freshmen into academic programs. Based on community data, students scoring near or above the 85th national percentile on the Cognitive Skills Composite are strong candidates for the Thomas Aquinas Program — NDP's advanced academic track. Students who would benefit from structured academic support may be placed in the St. Aloysius Gonzaga Program.
Important: The percentile thresholds listed here for track placement are community estimates based on Diocese of Phoenix admissions patterns — not officially published NDP figures. Contact the NDP Admissions Office directly and ask which HSPT composite scores are used for Thomas Aquinas Program eligibility. Getting that number in writing gives your child a specific, confirmed target before the December exam.
Your child can be admitted to NDP and still miss the advanced track by a thin margin. That's why aiming for the 85th percentile — not just the admission floor — is the smarter goal. The Quantitative Skills and Mathematics sections are especially predictive of readiness for NDP's honors and AP STEM coursework, which starts freshman year.
HSPT Dates, Registration, and the NDP Admissions Timeline for Scottsdale Families
Missing one deadline in this sequence can push your child's application to a secondary review cycle. Here is the full calendar in one place:
- September: HSPT registration opens at ndpsaints.org. Register immediately — testing seats are limited and fill fast.
- September–November: NDP application portal opens. Send teacher recommendation requests early. Teachers need several weeks of lead time, especially during the fall semester.
- December: HSPT administered on NDP's campus on a Saturday (exact date announced each fall). Have 7th grade transcripts and first-marking-period 8th grade grades ready to submit at the same time or shortly after.
- January 15: Application deadline. Every piece of the file — personal statement, recommendation letters, IEP or 504 documentation if applicable — must be in the portal by this date.
- Late January – February: Admissions decisions released, consistent with Diocese of Phoenix Catholic school norms.
Interviews are scheduled through the application portal. Not every applicant is called for one. A strong HSPT score can reduce the likelihood of an interview being required. A borderline score may trigger one — which is actually an opportunity for your child to strengthen a file that needs it.
Does a Strong HSPT Score Affect Notre Dame Prep Scholarship Awards in Arizona?
Yes — and this is where I've watched families leave money on the table by not setting a high enough prep target.
Merit scholarship consideration at NDP typically overlaps with the HSPT score review. Families targeting merit awards should aim for top-quartile performance: at or above the 75th national percentile on the Battery Composite, and ideally the 85th percentile on the Cognitive Skills Composite.
NDP administers its own merit scholarship process. The application portal and the Admissions Office at ndpsaints.org are the authoritative sources for current award amounts and specific score thresholds. Don't assume admission automatically triggers scholarship review — ask the Admissions Office directly whether a separate merit scholarship application is required and what its deadline is relative to January 15.
Families who research the merit threshold early — and set a prep goal based on that number rather than just the admission floor — give their children the most specific, motivating target to work toward. "Score as high as possible" is not a prep goal. "Hit the 85th percentile on the Cognitive Skills Composite" is.

HSPT Quantitative Skills and HSPT Prep in Scottsdale: The Section Most Families Underestimate
Of all five HSPT sections, Quantitative Skills is the one I've seen students most consistently underestimate — and it's also the one where targeted practice makes the biggest difference in the shortest time.
Here's why it's different from the rest. The Mathematics section tests computation and problem-solving your child can improve with standard math practice. Quantitative Skills tests abstract reasoning: number series, geometric comparisons, and non-verbal pattern recognition. That is not something a standard math textbook drills. I've seen students with strong math grades score at the 55th percentile in Quantitative Skills because they'd never practiced that type of question before.
This section — 52 questions in 30 minutes — feeds directly into the Total Cognitive Skills Composite, the score most closely linked to course-track placement and merit scholarship review at Notre Dame Preparatory. Moving from the 65th percentile to the 85th percentile in Quantitative Skills shifts the entire Cognitive Skills Composite in a meaningful way.
The reasoning skills tested here — identifying patterns, evaluating logical sequences, working with unfamiliar problem formats under timed pressure — are exactly what structured STEM Critical Thinking practice builds. That's not a marketing claim; it's a direct match between the skills the test measures and the skills our practice tests develop.
How NDP's Application Balances HSPT Score Against Grades, Interview, and Personal Statement
NDP reviews five factors: HSPT scores, academic transcripts (7th grade and first-marking-period 8th grade), an admissions interview for select applicants, a teacher or counselor recommendation letter, and a personal statement submitted through the application portal.
No single factor automatically disqualifies an otherwise strong applicant. A student with a 60th-percentile HSPT score but a 4.0 GPA and a sharp personal statement can still gain admission. A high HSPT score doesn't substitute for a missing recommendation letter or a blank personal statement field. I've seen both situations end badly.
The personal statement and interview reward clear, organized thinking — the same skills that strong essay writing practice builds. Even though the HSPT itself is entirely multiple-choice, your child's written and verbal communication matters at every other stage of this application.
Treat all five components as equally urgent. A weak spot in any one area creates unnecessary risk — regardless of what the overall acceptance rate looks like on paper.
Frequently Asked Questions: HSPT Score for Notre Dame Preparatory Scottsdale
Q: Is there a minimum HSPT score required for Notre Dame Prep admission?
A: NDP does not publish a hard cutoff score. Community data suggests students scoring at or above the 75th national percentile on the HSPT Battery Composite are well-positioned for admission. Students below the 50th percentile can still be admitted, but grades, the interview, and recommendation letters carry significantly more weight at that level. If your child is in that range, make sure every other part of the file is as strong as it can be.
Q: Can a high HSPT score earn my child a scholarship at Notre Dame Prep?
A: Yes, HSPT scores factor into NDP's merit award review. Families should aim for top-quartile performance — roughly the 75th percentile or higher on the Battery Composite — to be in the scholarship conversation. The Admissions Office at ndpsaints.org can confirm current award thresholds and whether a separate scholarship application is required beyond the standard admissions file.
Q: Which HSPT section matters most for NDP admissions?
A: All five sections are reviewed, but the Total Cognitive Skills Composite — combining Verbal Skills and Quantitative Skills — is most closely tied to academic readiness and course-track placement at NDP. Strong Quantitative Skills performance is especially relevant for students aiming for NDP's honors and AP STEM sequences, which begin freshman year. Don't let Quantitative Skills be an afterthought in your child's prep.
Q: Can my child take the HSPT at a different Catholic school and submit that score to NDP?
A: The HSPT may only be taken once per year. If your child tests at another Catholic school before NDP's December exam, that score is on record. STS policy requires all scores from multiple sittings within 12 months to be reported — so retaking is not a way to hide a lower result. Test once, at NDP's on-campus December exam, for the cleanest outcome. If your family is applying to NDP, that December date should be your child's first and only sitting.
Q: What accommodations are available for students with an IEP or 504 Plan?
A: NDP accepts current IEP and 504 Plan documentation — typically issued within the past year — during the application process. Extended time and other testing accommodations on the HSPT must be requested through the NDP Admissions Office before the December exam, not on test day. Submit your child's documentation as early as September when registration opens. Waiting until the January 15 deadline is too late for accommodation processing.
Q: What happens if my child is sick on HSPT test day and misses the December exam?
A: The HSPT is administered only once per year at NDP's campus. If your child misses the December date, call the NDP Admissions Office within 24–48 hours — not at the end of the week. The school may direct you to a makeup administration at another Diocese of Phoenix school, but makeup seats are not guaranteed and fill fast. With the January 15 application deadline about six weeks after the December exam, there is very little time to recover from a missed test date.
Q: How does NDP use HSPT scores for internal academic track placement?
A: Beyond admissions, NDP uses HSPT scores to place incoming freshmen into academic programs. Based on community data, students scoring near or above the 85th national percentile on the Cognitive Skills Composite are strong candidates for the Thomas Aquinas Program — NDP's advanced academic track. Students who would benefit from structured academic support may be placed in the St. Aloysius Gonzaga Program. These percentile figures are community estimates — ask the Admissions Office for the confirmed placement thresholds before your child's December exam. Your admission letter and your placement notification may arrive on different timelines, so ask about both.
Q: Are there official HSPT practice tests NDP recommends before the December exam?
A: NDP does not publish an official prep resource list. Scholastic Testing Service, the HSPT publisher, offers some preparation materials on their site. For the Quantitative Skills and Mathematics sections specifically, STEM Critical Thinking practice tests build the abstract reasoning and number-pattern skills that map directly onto those subtests. If your child is in 7th grade and targeting NDP, starting structured practice now — 12 to 18 months before the December exam — gives the best chance of a meaningful percentile improvement by test day.
Raise Your Child's HSPT Percentile Before the December Exam
The HSPT Quantitative Skills section is genuinely hard for students who haven't practiced abstract reasoning. I've watched prepared students move 15–20 percentile points on that section over a 12–18 month structured practice period. I've also watched students who started six weeks before the exam barely move at all. The difference isn't talent — it's time and the right kind of practice.
Standard math drills won't move the Quantitative Skills needle. Timed abstract reasoning practice will.
At stemcriticalthinking.com, our STEM Critical Thinking Practice Tests are built around number-pattern recognition, logical sequencing, and non-verbal reasoning under timed pressure — the exact skills that separate a 65th-percentile Quantitative Skills score from an 85th-percentile score at Notre Dame Preparatory Scottsdale.
If your child is targeting NDP for December 2025 or December 2026, the window to build those skills is open right now. Not in October.
