Archdiocese of Baltimore HSPT prep is the single most important academic task your 8th grader will tackle before high school applications close. Every student applying to any of the 18 Catholic high schools in the Archdiocese — from Calvert Hall to Mercy High School to Archbishop Spalding — must take this test. There are no exceptions, no waivers, and no retakes. I've watched students miss their first-choice school and lose scholarship money because they walked into the Baltimore HSPT practice test phase too late — not because they weren't sharp enough, but because November arrived before they'd ever seen a number series question. Start here, start now.

Does Every Archdiocese of Baltimore Catholic High School Require the HSPT?
Every one of the 18 high schools in the Archdiocese of Baltimore requires the HSPT. There is no opt-out and no alternative test. The Archdiocese administers a single, secure, annually updated version of the exam through STS. Your child submits one application through the common application portal and designates up to five schools to receive their scores.
That five-school limit matters. Choose your list thoughtfully before the common application deadline on December 10. STS sends scores to each school you designate — you cannot add schools after scores are released.
Individual schools may layer additional requirements on top of the HSPT. Archbishop Spalding requires a student essay. Mercy High School may require a campus interview or visit. The Catholic High School of Baltimore also requests a written statement. Some sites offer an optional 40-question Science or Catholic Religion subtest — check your target school's application checklist to confirm whether they request it. The HSPT itself, however, is universal across all 18 schools.
The No-Retake Rule: What It Means for Baltimore HSPT Test Prep
The Archdiocese of Baltimore HSPT can be taken exactly once. No retakes exist under any circumstances — not for illness, not for a bad testing day, not for a score lower than expected. The Archdiocese does schedule a make-up date for documented absences on the original test day, but that make-up is a first attempt, not a second chance.
That single-shot rule has real consequences. On the SAT, a student can test three or four times and submit their best score. Here, the score your child earns in November is the score that goes to every school on their list. There is no safety net, and there is no do-over.
Schools use HSPT scores for three separate purposes: admissions decisions, honors or advanced track placement, and merit scholarship awards. A composite score at the 75th national percentile or higher is generally competitive for admissions at selective schools like Archbishop Spalding. Scores at or above the 90th percentile — roughly a composite scaled score above 650 — are commonly associated with merit scholarship consideration, though thresholds vary by school and year. Confirm exact bands with each school's admissions office.
The HSPT Quantitative Skills Section: Why It Trips Up Most Baltimore Students
The Quantitative Skills section is 52 questions in 30 minutes. That is roughly 35 seconds per question with no calculator allowed. It tests number series, geometric comparisons, non-geometric comparisons, and quantitative reasoning — and none of those question types appear consistently in standard 8th grade math class.
Number series questions ask your child to identify the rule governing a sequence and predict the next term. Geometric comparison questions present two or three shapes or values and ask which is greater. These are not computation problems. They are pattern recognition and logical inference problems under time pressure. Students who practice them 20 or 30 times before test day process them almost automatically. Students who see them for the first time on November 15 lose 10 to 15 seconds per question just orienting to the format — and 35 seconds per question leaves no margin for confusion.
I've worked with students who were genuinely strong in math class but still struggled on Quantitative Skills their first time through a practice test. Once they recognized the specific pattern types, their accuracy on that section jumped considerably within two weeks. The skill is learnable — it just has to be practiced directly, not assumed to transfer from classroom math.
If you want a concrete place to build that skill before November, our STEM Critical Thinking Practice Tests are designed around exactly these question types — timed, no calculator, with the same reasoning demands your child will face on test day.
The Mathematics section (64 questions, 45 minutes) covers arithmetic, algebra, geometry, and problem-solving — closer to standard coursework, but still calculator-free. Together, Quantitative Skills and Mathematics account for 116 of the 298 questions, nearly 39% of the entire exam. These two sections offer the highest return on prep time of any part of the test.
Baltimore HSPT Prep for Public School Students: Closing the Familiarity Gap
If your child attends a public or independent private school, they face a real but fixable disadvantage most HSPT prep guides skip over. Students at Archdiocese of Baltimore Catholic elementary and middle schools receive in-school HSPT exposure throughout 7th and 8th grade — their teachers know the format, the pacing, and the question types. Your child does not have that background built in.
Public school students also have a different logistics situation on test day. They test on November 15 (Saturday) at a participating Catholic high school, not at their own school. Register as soon as the portal opens on September 9 — seats at convenient sites do fill up. Arriving at an unfamiliar campus for a high-stakes 2.5-hour exam adds stress your child does not need. If it is at all possible, drive to the testing site once before November 15 so the building is not a surprise on test morning.
The good news: targeted, section-specific practice can close the familiarity gap completely within 8 to 10 weeks. The question types are finite, the timing is fixed, and the format does not change year to year. Families who start structured prep in August consistently outperform those who begin in October, even when the October starters had stronger baseline skills.
Check-in begins at 8:30 a.m. Testing runs from 9:00 a.m. to approximately noon. Plan for the full morning. Bring two sharpened pencils, your registration confirmation, and a valid photo ID. No additional scratch paper is provided beyond the test booklet margins.
How HSPT Scores Are Used Across Archdiocese of Baltimore High Schools
The HSPT score your child earns does not work identically at every school — and most Baltimore HSPT prep guides don't spell this out clearly.
At Calvert Hall College High School and Loyola Blakefield, HSPT scores inform both admissions tier placement and academic track assignment for freshman year. The Cognitive Skills composite — which combines Verbal and Quantitative scores — carries particular weight because it reflects reasoning ability independent of prior schooling or GPA.
At Archbishop Spalding, HSPT scores directly influence merit scholarship consideration. The school uses test scores, GPA, and activities together when awarding scholarships. A difference of 5 to 10 percentile points can translate into a meaningful tuition difference over four years. That connection is worth understanding before your child sits down for a single prep session.
At Mercy High School, HSPT scores factor into admissions alongside a required interview. A student whose score is borderline but whose interview is strong may still receive an offer. But starting from a higher percentile score means your child enters that conversation from a position of strength, not damage control.
I've seen students with nearly identical GPAs get very different outcomes at the same school — and in most of those cases, the difference came down to how seriously each family treated the HSPT. The score is not the only factor, but it is the one factor every applicant can actually improve before December 10.
How to Prepare for the Baltimore HSPT: A Month-by-Month Plan
Below is a concrete prep calendar built around the Archdiocese of Baltimore's actual deadlines. Adjust the start based on when you are reading this.
- June–July: Build a baseline. Complete one untimed, full-length HSPT practice session. Identify your child's two weakest sections by raw score. Access STEM Critical Thinking practice materials focused on number series and quantitative reasoning. Don't try to fix everything yet — just find out where the gaps are.
- August: Targeted section practice — 3 sessions per week, 30 to 45 minutes each. Focus entirely on Quantitative Skills and Verbal Skills. No full-length timed tests yet. Track accuracy by question type, not just total score. Number series errors are usually about pattern recognition; verbal errors are usually about vocabulary. Treat them as separate skills.
- September 1–9: Register as soon as the portal opens on September 9. Public school families: select your testing site immediately — do not wait. Add Mathematics into the weekly practice rotation alongside Quantitative Skills and Verbal.
- September 10 – October 15: Rotate through all five sections each week. Complete one full-length timed practice test by October 1. Review every wrong answer by question type, not by section. Re-test those specific question types the following week — not the whole section.
- October 16 – November 7: Simulate test-day conditions twice — 298 questions, 141 minutes timed, no calculator, starting at 8:30 a.m. Score both attempts and compare national percentile estimates. Look for patterns in errors, not just totals.
- November 8–14 (Nov. 15 testers) or November 8–18 (Nov. 19 testers): Light review only. No new content, no new question types. Re-read notes on number series rules and verbal analogies. Sleep at least 8 hours the two nights before the exam. A rested brain outperforms a cramming brain every time.
Does the Baltimore HSPT Include an Essay? What to Know About School Writing Requirements
The HSPT itself contains no essay, no short answer, and no written response of any kind. All 298 questions are multiple choice with four answer choices each. There is no penalty for wrong answers — your child should mark an answer for every question, even when guessing.
That said, the absence of a writing component on the HSPT does not mean writing is irrelevant to Baltimore Catholic high school admissions. Several schools in the Archdiocese require a student essay submitted through the common application — separate from test day and separate from the HSPT entirely. Archbishop Spalding and The Catholic High School of Baltimore are two examples. These essays typically ask students to describe their reasons for applying, their academic goals, or a meaningful experience that shaped their character.
An 8th grader who has never practiced structured essay writing will struggle to produce a focused, well-organized response on a deadline. If your child is applying to any school that requires a written statement, start essay prep in October alongside HSPT prep. Analytical reasoning for the test and organized written argument for the essay are connected skills — and working on both at the same time reinforces each one.
Frequently Asked Questions: Archdiocese of Baltimore HSPT Admissions
Q: Can my child retake the HSPT if they are unhappy with their score?
A: No. The Archdiocese of Baltimore HSPT may be taken only once. There are no retakes under any circumstances, including illness or a personal emergency on test day. The make-up date exists only for documented absences — it is not a second attempt. Because your child gets one shot, focused section-specific practice — especially for Quantitative Skills — is the only way to influence the outcome before test day.
Q: When should we start preparing for the Baltimore HSPT?
A: Registration opens September 9 and the test falls November 15 (public and private school students) or November 19 (Catholic school students), so begin targeted practice no later than August. Students who start in June or July have time to work through all five sections systematically. Prioritize Quantitative Skills and Verbal Skills first, then rotate into Mathematics and Reading as the test approaches.
Q: Does our child's current school or testing site affect anything?
A: Yes, in two ways. First, 8th graders enrolled in an Archdiocese of Baltimore Catholic school test at their own school on November 19 — no separate site registration is needed. Second, public and private school students choose from available participating high schools for the November 15 Saturday date and should register early, because seats at popular sites fill up. Site choice does not affect scoring, but logistics and familiarity with the testing environment differ significantly. Drive to the site before November 15 if you can — arriving somewhere familiar on a high-stakes morning makes a real difference.
Q: What is the Quantitative Skills section and why is it the hardest section for most students?
A: The Quantitative Skills section contains 52 questions in 30 minutes — roughly 35 seconds per question with no calculator. It tests number series, geometric comparisons, non-geometric comparisons, and quantitative reasoning. Most 8th graders have never seen number series questions in their regular coursework, which is why this section catches them off guard. Students who complete 15 or more timed number series practice sets before test day consistently report less confusion on this section than those encountering these question types for the first time in November.
Q: What HSPT score is considered competitive for schools like Archbishop Spalding or Mercy High School?
A: Individual schools do not publish official cutoffs. Based on community-reported admissions outcomes, composite scores at the 75th national percentile or higher are generally competitive at selective schools like Archbishop Spalding and Mercy High School. Scores at the 90th percentile or above — corresponding roughly to a composite scaled score above 650 — are frequently associated with merit scholarship consideration. These are estimates, not official figures. Confirm current thresholds directly with each school's admissions office, as the competitive band shifts slightly year to year.
Q: How soon will we get HSPT scores back, and will the schools see them before we do?
A: Score reports are delivered to families approximately one month after the November test date, typically in December. STS sends scores directly to each student's designated high schools at the same time — schools do not receive scores before families, but both receive them simultaneously. You will not have a window to review the score before admissions offices see it. All five schools your child designates receive the same score report at the same time, regardless of selectivity.
Q: My child has an IEP or 504 plan — how do we request HSPT testing accommodations?
A: Accommodations for the Archdiocese of Baltimore HSPT must be requested through the Archdiocese directly, not through STS or the individual high school. Submit documentation — including a current IEP or 504 plan and any psycho-educational evaluation — as early as possible after registration opens on September 9. Requests submitted after mid-October may not be processed in time for the November test date. Visit the Archdiocese of Baltimore Office of Catholic Schools website (archbalt.org) to confirm the exact documentation deadline for the current cycle. Approved accommodations are communicated to your child's testing site before test day.
Q: Does the HSPT include an essay or writing sample?
A: No. The Archdiocese of Baltimore HSPT is entirely multiple choice across five sections — Verbal Skills, Quantitative Skills, Reading, Mathematics, and Language. There is no essay or written response on the test itself. However, several individual high schools — including Archbishop Spalding and The Catholic High School of Baltimore — require a separate student essay submitted through the common application. That essay has its own deadline aligned with the December 10 common application deadline and should be drafted and revised well before then.
Build Your Child's HSPT Score Before November — One Section at a Time
The Archdiocese of Baltimore HSPT gives your child one attempt. That is it. The Quantitative Skills and Mathematics sections together make up nearly 39% of the exam — and both test the kind of pattern recognition and logical reasoning that standard 8th grade coursework simply does not practice under timed, no-calculator conditions.
The students I've seen score in the 80th percentile or higher on the Baltimore HSPT are almost always the ones who did targeted, timed practice across 8 to 10 weeks — not just the students who were strong in math class. Classroom math and HSPT math are related but not the same. The format, the pacing, and the question types require direct preparation.
At stemcriticalthinking.com, our STEM Critical Thinking Practice Tests are built around the exact reasoning demands of the HSPT's Quantitative Skills and Mathematics sections. Number series, geometric comparisons, pattern recognition, and quantitative reasoning under strict time pressure — these are the question types our practice tests target directly. Every session is timed, calculator-free, and structured the same way your child will face on November 15 or 19.
If your child is applying to Archbishop Spalding, Calvert Hall, Mercy High School, Loyola Blakefield, or any of the 18 Archdiocese of Baltimore high schools, start building that skill now — not in October.
