I've seen families walk out of Marist High School's admissions night not realizing that the HSPT STEM critical thinking sections would decide not just whether their child got in — but how much they'd pay for the next four years. Marist awards up to $4,000 per year in merit scholarships based entirely on HSPT percentile scores. The two sections driving those scores — Quantitative Skills and Mathematics — test pattern recognition, logical reasoning, and applied math under strict time pressure. Miss those sections in your prep, and you're leaving real money behind.

What HSPT STEM Critical Thinking Questions Actually Look Like
The HSPT doesn't use the label "STEM Critical Thinking" anywhere in its official section names. These skills live inside two sections: Quantitative Skills and Mathematics. Together they account for 116 questions — more than a third of the entire exam.
Quantitative Skills (52 questions, 30 minutes) tests three things: number series completion, geometric and non-verbal comparisons, and quantitative reasoning. A number series question gives your child a sequence like 3, 6, 11, 18, 27 and asks what comes next. The rule here — adding 3, then 5, then 7, then 9 — has to be spotted and extended in under 35 seconds. Students who think systematically about patterns handle these quickly. Students who guess burn time they don't have.
Mathematics (64 questions, 30 minutes) shifts into applied problem-solving. Questions cover pre-algebra, geometry, word problems, and data interpretation. Your child might read a bar graph and answer three follow-up questions, or work through a two-step percent problem entirely in their head — no calculator, no scratch app, just mental math and structured reasoning.
The connection to STEM critical thinking is direct. Pattern recognition, multi-step quantitative reasoning, and data interpretation are core STEM skills — and the HSPT measures all three under real time pressure.
Marist High School STEM Test Prep: Why Generic Math Practice Isn't Enough
Standard math homework and school tests don't replicate HSPT question formats. Your child's algebra class rewards showing work, using a calculator, and solving one problem type at a time. The HSPT rewards speed, pattern fluency, and the ability to switch between problem types every 28–35 seconds — with no calculator.
In my experience, students who prep with generic math workbooks tend to hit a ceiling around the 70th–75th percentile. They know the math. What they haven't built is the rapid recognition and mental calculation speed the HSPT specifically demands. That gap is exactly what STEM critical thinking practice closes.
Effective Marist HSPT prep targets three specific skills — all without a calculator:
- Mental arithmetic fluency: Multiplying two-digit numbers, computing percentages, and estimating square roots in under 15 seconds
- Pattern extension: Recognizing arithmetic, geometric, and combined-rule sequences in under 10 seconds
- Data reasoning: Pulling a conclusion from a table or chart in one reading, not two
These are trainable skills. Students who practice them under timed, test-format conditions — rather than just reviewing math concepts — consistently move up 10–20 percentile points before test day.
HSPT Score Strategy for Marist: Which STEM Critical Thinking Percentile Is Competitive?
Marist has not published a minimum admission cutoff, and the process is holistic. Your child's 7th and 8th grade transcripts, a recommendation letter, and demonstrated personal and spiritual growth all factor in. No single element decides the outcome.
That said, Marist's published scholarship thresholds give you a concrete target:
- 85th–89th national percentile: $1,000 per year, renewable with a B average
- 90th–94th national percentile: $2,000 per year, renewable with a B average
- 95th–99th national percentile: $4,000 per year, renewable with a B average
Worth verifying directly with Marist: scholarship renewal is tied to maintaining a B average, but the exact GPA threshold can shift year to year. Ask the admissions office to confirm the current renewal requirement when you register.
Over four years, the difference between the 84th percentile and the 95th percentile is $16,000. That's not a motivational talking point — it's money. Target the 85th percentile as your floor, and aim for the 95th if your child's academic record is strong.
One thing most families don't know to ask about: Marist may also use a Local Percentile Rank (LPR), which compares your child only to other students who tested at Marist that year. The LPR can differ from the national percentile by several points in either direction. Ask the admissions office directly whether LPR or national rank carries more weight for scholarship decisions in the current cycle.
The One-School Rule: A STEM Critical Thinking HSPT Decision That Affects Chicago Catholic High School Admissions
Every family applying to an Archdiocese of Chicago Catholic high school faces the same rule: your child may only sit the HSPT at one school per testing cycle. If your child registers at a different Catholic high school, Marist will not have a test score to use for admission or scholarship review.
That one rule has real money attached to it. If Marist is your first-choice school, register at Marist. The $25 registration fee is the same everywhere. The test content is identical at every school. The only thing that changes is which school receives the official score report.
If your child is genuinely undecided between two schools, factor this in: Marist's scholarship program is explicit, tiered, and renewable. A student who scores at the 90th percentile and tests at Marist receives $2,000 per year for four years — $8,000 total, assuming a B average is maintained. The same score at a school without an equivalent merit program earns nothing. Make your school selection before registration opens in late November, and make it deliberately.
HSPT Registration, Accommodations, and Make-Up Dates for Marist STEM Critical Thinking Test Prep Planning
Registration for the Marist HSPT typically opens in late November — for the 2025–26 cycle, that date was November 21, 2025. The exam fee is $25. The primary test date is the first Saturday of December (December 6, 2025 for the 2025–26 cycle). Always confirm current dates at marist.net, since the Archdiocese of Chicago adjusts the calendar each year.
If your child has a documented disability, submit IEP, 504, or ILP paperwork to Marist's admissions office before the registration deadline — not after. The Archdiocese coordinates accommodations centrally, and processing takes time. Extended time is available, but documentation must be current and submitted early. Don't wait until after your child registers to start that process.
Marist offers make-up exam dates for students who miss December test day due to illness or another unavoidable conflict. Contact the admissions office right away after a missed test. Make-up availability is managed by Marist directly and doesn't always line up with make-up dates at other schools. Medical documentation may be required.
Admission decisions are communicated in spring on a date set by the Catholic Schools Office — for the 2026–27 cycle, that date was April 4, 2026.
Frequently Asked Questions: Marist High School HSPT and STEM Critical Thinking Prep
Q: What does the HSPT STEM Critical Thinking section actually test?
A: HSPT STEM critical thinking skills show up most in the Quantitative Skills and Mathematics sections. These sections test pattern recognition through number series, data interpretation using tables and charts, logical reasoning with multi-step problems, and applied math problem-solving — all without a calculator. Your child must identify relationships between quantities, extend numeric patterns, and draw conclusions from presented data. Scores on these two sections carry significant weight in both admission decisions and merit scholarship eligibility at Marist.
Q: How is STEM Critical Thinking different from the standard HSPT Quantitative Skills section?
A: The Quantitative Skills section focuses on number series completion and non-verbal geometric comparisons. STEM Critical Thinking is broader — it also requires applied reasoning in science-style data contexts: reading a graph, interpreting a trend, or working through a multi-step real-world scenario. Quantitative Skills is one piece of STEM critical thinking, not the whole picture. Students who only drill number series miss the applied reasoning layer that separates the 85th percentile from the 95th — a difference worth exactly $3,000 per year in Marist scholarships.
Q: How many questions are on the HSPT and how much time is given for each section?
A: The full HSPT contains 298 questions across five sections in 150 minutes total. The Quantitative Skills section is 52 questions in 30 minutes — about 35 seconds per question. The Mathematics section is 64 questions in 30 minutes — about 28 seconds per question. Those two STEM-heavy sections together give your child 116 questions in 60 minutes with no calculator. Because there is no guessing penalty, answer every question even when you're unsure. Skipping questions to return to them later wastes time you simply don't have at that pace.
Q: What's the best way to practice STEM Critical Thinking skills for the Marist HSPT?
A: Timed, section-specific practice under no-calculator conditions is what actually works. Generic math worksheets don't replicate the pattern-recognition and logical-reasoning format of HSPT questions — I've seen students who aced their school math tests still struggle on their first HSPT practice run because the format was new. The STEM Critical Thinking practice tests at stemcriticalthinking.com are built around exactly the skill areas tested in the HSPT's Quantitative Skills and Mathematics sections: number series logic, data interpretation, and multi-step applied reasoning, all timed to match real test conditions. Starting in 7th grade gives your child a full year to build fluency rather than cramming it into 8–10 weeks.
Q: Does my child have to take the HSPT at Marist, or can they test at another Catholic high school?
A: Your child may only take the HSPT at one Archdiocese of Chicago Catholic high school per testing cycle — this is a firm rule. If they test at a different school, Marist will not receive a score for admission or scholarship review. To qualify for any of Marist's merit scholarships, your child must register for and sit the HSPT at Marist. The test content is identical everywhere; only the score report destination changes. Make your site selection deliberately before registration opens in late November.
Q: What HSPT percentile score does Marist typically look for in admitted students?
A: Marist hasn't published a minimum cutoff, and no single factor decides admission. That said, scores at the 76th percentile and above are classified as "high" nationally — that's a reasonable floor for competitive applicants. For honors-track placement and scholarship eligibility, target the 85th percentile at minimum. One thing to ask about: Marist may compare your child's score against a Local Percentile Rank drawn only from students who tested at Marist that year. The LPR can differ from the national percentile by several points — ask the admissions office which rank carries more weight for course placement and scholarship review in the current cycle.
Q: Are there merit scholarships available based on HSPT performance, and how do we apply?
A: Yes, and no separate application is needed — Marist awards these automatically based on your child's HSPT national percentile rank. Scores at the 85th–89th percentile earn $1,000 per year; the 90th–94th percentile earns $2,000 per year; the 95th–99th percentile earns $4,000 per year. All scholarships are renewable annually with a B average — verify the exact GPA threshold with Marist's admissions office, as it can be updated. Over four years, a student at the 95th percentile receives $16,000 total. That makes targeted HSPT STEM critical thinking prep one of the highest-return investments available to an 8th grader in the Chicago area.
Q: Are there make-up HSPT dates if my child is sick on the December test day?
A: Yes. Marist offers make-up exam dates for students who miss the primary December test date. Contact the Marist admissions office directly as soon as possible after a missed test — don't wait. Make-up availability and dates are set by Marist and the Archdiocese of Chicago and are not guaranteed to match make-up dates at other Catholic high schools. Have a reason documented; medical documentation may be requested.
Q: Can my child get extended time on the HSPT if they have an IEP or 504 plan?
A: Yes, extended time is available with proper documentation — IEP, 504 plan, or ILP. Submit paperwork to Marist's admissions office well before the registration deadline; the Archdiocese processes accommodations centrally and needs lead time. If your child had a new evaluation completed in the fall of 8th grade, submit that most current version. Don't wait until after registration. Contact marist.net directly to confirm the exact documentation deadline for the current testing cycle, since it shifts year to year.
