Archbishop Riordan HSPT prep starts with one fact every family needs to know: your child gets exactly one shot at this test. The HSPT falls on a single Saturday in early December — no makeup date, no second chance that admissions cycle. For the Class of 2031 (fall 2026 enrollment), that Saturday will follow the same early-December pattern used for the Class of 2030, when the test was held on December 6, 2025. The application Priority Deadline lands five days before the test itself. I've watched students arrive underprepared simply because their families didn't realize how tight the window actually is. This guide gives you concrete score targets, a week-by-week September-to-December prep timeline, and a strategy for every part of Riordan's application — including the personal statement video that most other prep resources get completely wrong.

What HSPT Score Is Competitive for Archbishop Riordan HSPT Admissions?
Riordan does not publish a minimum HSPT cutoff score. Based on community-observed patterns — not official Riordan figures — competitive applicants typically land at or above the 75th national percentile on the HSPT Battery composite. For the Honors Engineering Program pathway, the realistic target is the 85th percentile or higher.
In terms of scaled scores (200–800 per section), a score of 550–650 per section is generally considered strong. The Cognitive Skills Quotient (CSQ) — which combines Verbal and Quantitative scaled scores — gets particular attention because it signals reasoning ability independent of classroom preparation.
Here is what most prep timelines miss: Riordan became co-ed in 2020. Before that, the applicant pool was all-male. Today, Riordan draws from a much larger group of Bay Area 8th graders. That expanded pool has raised the effective score bar. A percentile that felt comfortable five years ago may not carry the same weight now. Target the 80th percentile as your baseline goal and the 85th as your scholarship-competitive target.
HSPT scores also determine freshman course placement and scholarship eligibility — including the St. Francis Scholars program. A strong score on test day does triple duty: admissions, placement, and financial aid. Every point matters.
- General admissions: 75th–80th national percentile on Battery composite
- Scholarship consideration (St. Francis Scholars): 85th percentile or above
- Honors Engineering Program: 85th+ percentile, with strong 7th–8th grade math/science grades
- Scaled section scores: 550–650 range (out of 800) per section is competitive
Archbishop Riordan HSPT Prep Timeline: September to December
The application opens in early September. That date is not just a paperwork milestone — it is your prep start signal. A 10–12 week structured plan fits exactly between early September and the December test date. Here is how to use that time.
Weeks 1–3 (September): Diagnostic and Foundation
Take a full-length HSPT diagnostic test under timed conditions. Score each section separately. Find your child's two weakest sections — most students struggle most with Quantitative Skills and Language. Spend these three weeks reviewing core concepts: number series patterns, geometric comparisons, grammar rules, and punctuation conventions. Don't try to cover all five sections at once during this phase. Pick the weakest two and go deep.
Weeks 4–6 (October): Targeted Section Drilling
Rotate through all five sections with timed, section-specific practice sets. The Quantitative Skills section — 52 questions in 30 minutes — demands roughly 35 seconds per question. Students who haven't practiced pacing will run out of time before they finish. Use October to build speed alongside accuracy, not just correct answers.
Weeks 7–9 (Late October – November): Full Practice Tests and Application Materials
Shift to two full-length timed practice tests per week. After each test, spend 30 minutes reviewing every wrong answer — not just the ones that felt hard. Patterns in wrong answers reveal reasoning gaps that formula review alone won't fix. This is also the window to begin drafting the student personal statement video script and the parent statement. Starting the video script in Week 7 or 8 gives your child enough time to record multiple takes and choose the best one — not just the one that was finished before the deadline.
Weeks 10–12 (Late November – December 1): Final Review and Submission
Submit the Riordan application by December 1 — the Priority Deadline required to sit for the HSPT at Riordan. In the final week before the test, reduce practice test volume. Do one timed section per day, keep sleep consistent, and confirm test-day logistics: location, required ID, and what to bring. Pencils and scratch paper are provided. No devices are permitted.
HSPT Quantitative Reasoning and STEM Critical Thinking: Why They Overlap
The HSPT Mathematics section covers arithmetic, algebra, and geometry — content your child has seen in class. The Quantitative Skills section is different. Its 52 questions include number series, geometric comparisons, and non-standard reasoning problems. No 8th-grade math class specifically prepares students for this section. I've seen students with straight-A math grades score below the 60th percentile on Quantitative Skills simply because they'd never practiced this style of problem.
These questions reward pattern recognition, logical deduction, and structured analysis — the same cognitive skills built through STEM critical thinking practice. When your child encounters a number series like 3, 6, 11, 18, 27 and must identify the next term, they are not applying a memorized formula. They are reasoning analytically about structure and relationships.
This is why STEM Critical Thinking practice tests are the most direct supplemental prep you can do for the Quantitative Skills section. They build the underlying reasoning layer that the HSPT specifically tests — and that math homework alone does not develop.
For Riordan's Honors Engineering Program applicants, there is an additional reason to prioritize this section. Strong quantitative reasoning scores signal exactly the kind of analytical thinking the program values, alongside 7th–8th grade math and science grades.

Personal Statement Video and Parent Statement for Archbishop Riordan: What Most Applicants Miss
Almost every HSPT prep resource treats Riordan's personal statement as a written essay. It is not. Riordan requires a student personal statement video — a filmed, spoken submission. That distinction changes everything about how you prepare.
Riordan is not evaluating cinematography. They are evaluating clarity of communication, authentic self-expression, and values alignment with Riordan's Marianist mission: "Think More, Do More, Be More." Your child should speak directly to camera, make eye contact, and use specific personal examples rather than generic statements about wanting to be a good student. A brief, focused script that is rehearsed but sounds natural outperforms a longer delivery that sounds performed.
Practical steps: write a script first, then practice delivering it without reading. Record three or four versions. Watch them back and cut filler phrases. Choose a quiet, well-lit location — plain backgrounds work better than busy ones. Submit the version that feels most like your child, not the most technically polished take.
The parent statement is equally underestimated. Write it in your own voice, not in formal admissions language. Connect your family's values explicitly to Riordan's Marianist identity. Give one or two concrete examples of how your child shows service, community, or intellectual curiosity. Admissions readers review dozens of parent statements; specificity and sincerity stand out.
Families who treat the video and parent statement as afterthoughts — rushing them in the final week before December 1 — produce submissions that undermine an otherwise strong HSPT score. Plan four to six weeks for both components.
Archbishop Riordan Admissions Decisions, Engineering Track, and HSPT Scholarships
When Will You Hear Back?
Riordan does not publicly post a specific decision-release date. Decisions come out in winter or spring following the December test. Monitor the Parent Portal checklist — that is where status updates appear. Don't rely on email alone. Build the habit of checking the portal weekly starting in January.
Honors Engineering Program: What the Application Actually Requires
The Honors Engineering Program requires more than a strong HSPT score. Riordan evaluates 7th and 8th grade math and science grades specifically for this pathway, and demonstrated interest in engineering — through coursework, projects, competitions, or extracurricular activities — also factors in. Generic statements about liking science are not enough. In the personal statement video, reference a specific project, problem, or experience that shows genuine engagement with engineering. That specificity is what separates strong Honors Engineering applications from average ones.
Scholarship Strategy: Why the December 1 Deadline Is the Real Lever
HSPT scores feed directly into scholarship consideration at Riordan, including the St. Francis Scholars program. Additional aid may be available through Bay Area Catholic school scholarship networks, Archdiocesan grants, and need-based programs. Submit by December 1 — not January 11. Late applicants risk missing merit award cycles entirely. Contact the Riordan financial aid office early in the fall to understand Archdiocesan grant timelines, which operate on a separate schedule from merit scholarships and require distinct financial documentation. Getting that conversation started in September puts your family ahead of most applicants.
Frequently Asked Questions: Archbishop Riordan High School HSPT Admissions
Q: When should my child start preparing for the HSPT for Archbishop Riordan?
A: Start no later than the first week of September. Riordan's HSPT falls on a single Saturday in early December — December 6, 2025 for the Class of 2030, with similar timing expected for the Class of 2031 — giving you a firm 10–12 week prep window. Waiting until October cuts your review time by roughly 30% and leaves no buffer for revisiting weak sections before the December 1 Priority Deadline. A September start also lets your child work on the personal statement video and parent statement in Weeks 7–8, without rushing them alongside final test prep.
Q: What HSPT score does Archbishop Riordan require?
A: Riordan does not publish a minimum cutoff. Community-observed data — not official Riordan figures — suggests competitive applicants score at or above the 75th–85th national percentile on the Battery composite. Riordan became co-ed in 2020, and that expanded applicant pool has raised the effective score bar since then. Target the 80th percentile for general admissions and the 85th percentile for scholarship and Honors Engineering consideration. Scaled section scores in the 550–650 range (out of 800) are generally regarded as competitive, though GPA, the personal statement video, and recommendations all weigh into the final decision.
Q: Does Riordan accept the SSAT or ISEE instead of the HSPT?
A: No — Riordan requires the HSPT only. Many Bay Area families applying to both Catholic and independent private schools end up preparing for two different tests at the same time. HSPT Quantitative Skills problems — number series, geometric comparisons — have no direct equivalent on the SSAT or ISEE, so dedicated HSPT prep is essential regardless of what other schools require. If your child sits for the HSPT at another Bay Area Catholic high school, those scores are automatically shared with Riordan through the regional score-sharing network. Testing location does not matter.
Q: How does HSPT quantitative reasoning connect to STEM critical thinking?
A: The HSPT Quantitative Skills section tests analytical pattern recognition — number series, geometric comparisons, non-standard reasoning — that no standard 8th-grade math curriculum covers directly. These are the same reasoning skills built through STEM critical thinking practice. Students who train on STEM-style reasoning problems before the HSPT perform measurably better on the Quantitative Skills section than students who only review classroom math. STEM Critical Thinking practice tests at stemcriticalthinking.com are calibrated for 8th–10th graders and build exactly this analytical layer, making them the most direct supplemental prep for Riordan applicants targeting a strong Quantitative Skills score.
Q: How important is the student personal statement video compared to the HSPT score?
A: Riordan's review is holistic, and no single component automatically overrides another. The video is uniquely high-stakes because it cannot be revised after submission. Admissions reviewers are assessing communication clarity, values alignment with Riordan's Marianist identity, and authentic character. To prepare your child: script a specific answer to "why Riordan?" — not a general answer about wanting a good education, but a specific answer about this school and its community. Record at least two versions and choose the one that sounds most like your child, not the most polished take.
Q: Does applying to Riordan's Honors Engineering Program require anything extra?
A: Yes. Beyond the standard application, Riordan evaluates 7th and 8th grade math and science grades and documented demonstrated interest in engineering for this pathway. One often-overlooked opportunity: the personal statement video is a direct chance to articulate that engineering interest with specificity. Mentioning a robotics competition, a self-directed coding project, or a specific design challenge gives admissions reviewers concrete evidence — far more effectively than a general statement about enjoying science class. A HSPT composite at or above the 85th percentile is advisable for this track.
Q: Can HSPT scores qualify my child for merit scholarships at Riordan?
A: Yes. Riordan uses HSPT scores in scholarship consideration, including the St. Francis Scholars program. The December 1 Priority Deadline is the key lever — submitting by that date keeps your child in consideration for merit awards that may not be available to January 11 applicants. Archdiocesan grants and need-based programs at Riordan operate on separate timelines and require distinct financial documentation. Contact the Riordan financial aid office in September — not December — to understand all available aid pathways alongside merit scholarships.
Q: What happens if my child applies for Riordan's RSP learning support program?
A: RSP applicants submit a recent psycho-educational evaluation — typically within the past three years, though Riordan may require a more recent evaluation depending on the academic year — and participate in an RSP staff interview, in addition to the standard application requirements. Applying for RSP is a separate evaluation track focused on whether Riordan's support resources are the right fit for your child's specific documented needs. It does not automatically disadvantage a student in the general admissions pool. Confirm the acceptable evaluation timeframe directly with Riordan's admissions office before submitting — an outdated evaluation can delay your child's review.
Start Your Archbishop Riordan HSPT Practice the Right Way
The students who score in the 85th percentile on Riordan's HSPT aren't always the ones who studied the most hours. They're the ones who practiced the right kind of thinking. The Quantitative Skills and Verbal Skills sections reward analytical reasoning that most classroom prep never builds directly — and the Language section tests grammar and composition in ways that also show up in your child's personal statement video and parent statement.
At stemcriticalthinking.com, our STEM Critical Thinking Practice Tests are built for 8th–10th graders and train exactly the pattern recognition and logical reasoning the HSPT Quantitative Skills section tests. Our Essay Writing Practice Tests sharpen the grammar and composition skills the HSPT Language section evaluates — and they build the clear, structured thinking your child needs to script a strong personal statement video and write a compelling parent statement.
Both practice test types are browser-based, free to start, and designed to fit around a full 8th-grade schedule. If your child is targeting Archbishop Riordan for fall 2026, start in September, follow the timeline in this guide, and use our practice tests to close the reasoning gap before that one December test date arrives.
