The Mercy High School Burlingame HSPT gives your daughter exactly one opportunity to put her best score on the table — no retakes, no second attempts within the same admissions cycle. Families who want to know how to get into Mercy High School Burlingame quickly realize the HSPT is not a casual placement quiz. For a competitive all-girls Bay Area Catholic school with a serious STEM Pathways Program, this is a high-stakes standardized exam that shapes both admissions decisions and scholarship awards. I've worked with 8th graders who walked into December underprepared because their parents assumed the HSPT was low-stakes. It isn't. This guide gives you the specific benchmarks, timeline, and section-by-section strategy you need before that December test date.

What HSPT Score Does Mercy High School Burlingame Expect?
Mercy does not publish a minimum HSPT cutoff score. The national mean scaled score is 500 per section — that's the average across all HSPT test-takers nationwide, including students applying to less selective schools in less competitive markets.
Bay Area Catholic schools draw from one of the most academically competitive applicant pools in the country. Peer schools in the region — Notre Dame Belmont, Sacred Heart Prep, Saint Ignatius — consistently enroll students scoring well above national averages. At Mercy specifically, targeting scaled scores of 560–580+ per section — roughly the 75th national percentile — is a sound baseline for a competitive application.
Your Battery Composite is the combined score across all five sections and the single number that summarizes overall performance. Aiming for a Battery Composite at or above the 75th national percentile puts your daughter in a strong position. Scores in the 85th percentile range open up merit scholarship consideration.
Keep perspective: a strong HSPT score paired with a 3.5+ GPA and a solid teacher recommendation makes a compelling file. A high HSPT score with a 2.8 GPA is a harder case for any Admissions Committee to advance. The HSPT is one piece — but it is the only standardized piece. When GPAs cluster close together, it carries a lot of weight.
Bay Area vs. National Norms: The HSPT national percentile compares your daughter to all students who took the HSPT across the country. A score at the 70th national percentile might still be below the typical score of Mercy's admitted class — because Bay Area applicants tend to cluster higher than the national average. Think in Bay Area competitive terms, not just national terms.
Mercy High School Burlingame Admissions Timeline: September Through March
Getting the calendar right prevents two common and avoidable mistakes: missing the Early Bird scholarship deadline and waiting too long to book the required Shadow Day.
- Spring (March–May, year before 9th grade): Many middle schools offer the HSPT Pre-Test. Timing varies by school — check with your daughter's middle school directly. If she takes it, use that score as a diagnostic to identify which of the five sections needs the most attention before fall prep begins.
- August–September: Begin structured HSPT prep. This is the latest comfortable start for a December test date. Starting in June or July gives you more runway.
- September–October: Submit the Mercy application. Schedule your Shadow Day visit — seats are limited and fill quickly in fall.
- Late November (Early Bird deadline): Submit all Early Bird materials. This is also the hard deadline for AMES accommodation requests (IEP/504 documentation).
- Early December: HSPT at Mercy's campus (December 6, 2025 for the Class of 2030). Testing here is required for scholarship eligibility.
- January 30: Middle school transcripts and teacher recommendation letters due.
- Early January: Final application deadline for all other materials.
- March: Admissions decisions released (March 20, 2026 at 4:00 p.m. for the 2025–26 cycle — verify the date each year).

Your 12-Week Mercy High School Burlingame HSPT Prep Plan
Twelve weeks — starting no later than early September — is enough time for a well-organized student to make real gains on all five HSPT sections. Here is how to structure it.
- Weeks 1–2 (Diagnostic Phase): Take a full-length timed practice HSPT under real conditions — all 298 questions, 150 minutes, no breaks. Score each section. Identify the two sections with the lowest percentile scores. Those become your primary targets for the next month.
- Weeks 3–6 (Focused Drill Phase): Spend the majority of daily study time on your two weakest sections. For Quantitative Skills, drill number series, geometric comparisons, and non-geometric comparisons separately — these are distinct question types that reward pattern recognition, not calculation speed. For Mathematics, cover arithmetic, pre-algebra, basic geometry, and statistics. For Verbal Skills, build vocabulary through analogy and synonym practice.
- Weeks 7–9 (Balanced Practice Phase): Rotate through all five sections weekly. Time every practice set strictly. The Verbal Skills section gives you only 16 minutes for 60 questions — that's about 16 seconds per question. Build that reflex now, not in December.
- Weeks 10–11 (Full Simulation Phase): Run two complete timed practice tests under real testing conditions. After each one, review every missed question — understand the reasoning pattern, not just the correct answer.
- Week 12 (Consolidation): Light review only. Focus on question types that still feel shaky. Sleep and stress management matter more this week than cramming new content.
Use the Spring Pre-HSPT as Your Starting Point: If your daughter's middle school offers the HSPT Pre-Test in spring, that score is your earliest diagnostic. A Quantitative score below the 60th percentile means Quantitative Skills should anchor the entire fall prep plan. Don't wait until August to find out where the gaps are.
HSPT Quantitative Skills and STEM Reasoning: Where Mercy Applicants Are Often Surprised
In my experience, the Quantitative Skills section is the one that most surprises 8th graders — and it is directly tied to the kind of STEM critical thinking that Mercy's curriculum emphasizes from day one.
The section gives you 52 questions in 30 minutes — roughly 34 seconds per question. Question types include number series (identify the pattern, supply the next term), geometric comparisons (which figure is larger?), and non-geometric comparisons (which value is greater, given two expressions?). None of these require long calculation. All of them require rapid pattern recognition and logical inference.
This is exactly the cognitive skill set Mercy's STEM Pathways Program builds throughout high school. An applicant who demonstrates strong quantitative reasoning on the HSPT signals readiness for Mercy's college-preparatory math and science sequence. Weak quantitative scores, by contrast, can raise placement questions even when other sections are strong.
For prep, timed STEM critical thinking practice — specifically exercises that ask your daughter to identify logical patterns and evaluate quantitative relationships under a clock — gives you the most focused preparation for this section. Generic HSPT prep books often lump Quantitative Skills together with Mathematics and treat them the same way. They are not the same. Quantitative Skills is a reasoning test. Mathematics is a computation test. Prep them separately.
The Mathematics section (64 questions, 45 minutes) covers arithmetic, pre-algebra, geometry, and statistics. This section rewards content knowledge more directly. Both sections are critical for a strong Battery Composite.
Testing at Mercy's Campus vs. Another School: What Actually Changes
The HSPT is administered across the Archdiocese of San Francisco network, which means your daughter can technically sit for the exam at Notre Dame Belmont, Sacred Heart Prep, or any other participating school — and Mercy will receive those scores.
There is one significant difference: merit scholarship eligibility. Only students who test on Mercy's campus on the designated December date qualify for academic scholarships. Testing at another school removes that option for the entire cycle.
One more thing worth knowing: all HSPT scores from every school where your daughter tested are reported to all schools in the network where she applied. There is no strategy in testing at multiple schools. One test, fully prepared, at Mercy's campus in December is the right approach for most applicants.
Score Sharing in the Archdiocese Network: Bay Area Archdiocesan Catholic high schools share HSPT scores with each other. If your daughter is applying to Mercy, Notre Dame Belmont, and Sacred Heart Prep simultaneously, all three schools see all scores from every test she sat. One excellent performance is worth far more than multiple attempts.
Mercy High School Burlingame HSPT Accommodations: The AMES Program
Mercy provides extended time accommodations for students with an active IEP, 504 Plan, or qualifying professional evaluation through the AMES (Accommodated Mercy Entrance Support) program. This is a meaningful — and underreported — piece of the admissions process for families managing learning differences.
The critical detail: AMES documentation must be submitted by the Early Bird deadline in late November. That is weeks before the final January deadline. If you wait until January to submit accommodation paperwork, your daughter will sit for the December HSPT without extended time. There is no retroactive adjustment.
Qualifying documentation typically includes an active IEP, a current 504 Plan, or a professional psychoeducational evaluation. Contact Mercy's admissions office before September to confirm exactly which documents are accepted for the current cycle and to understand the extended-time format used on the Mercy campus HSPT date.
I've seen families lose accommodation eligibility because they assumed the January deadline applied to everything. For AMES, it does not. Mark the late-November Early Bird deadline in your calendar the moment you decide Mercy is on your daughter's list.
How the Mercy High School Burlingame Shadow Day Fits Into Admissions
The Shadow Day is not optional. Mercy requires all applicants to complete a campus visit where your daughter attends a full school day alongside current students. It is part of the evaluated application — not an informational tour you can skip.
Shadow Days are scheduled through Mercy's admissions office in the fall. Spots are limited, and families who wait until October or November often find the most convenient dates already booked. Contact Mercy's admissions team as early as September.
The visit matters beyond the logistics. Your daughter gets a real look at Mercy's classroom culture and pace before she commits. The admissions team gets an impression of genuine interest. Go in prepared — know something specific about Mercy's STEM Pathways Program and have a few real questions ready to ask the student host.
Frequently Asked Questions: Mercy High School Burlingame HSPT Prep and Admissions
Q: What HSPT score do I need to get into Mercy High School Burlingame?
A: Mercy does not publish a cutoff, but targeting the 75th national percentile — roughly scaled scores of 560–580+ per section — is a sound goal for a competitive Bay Area Catholic school. Bay Area applicant pools consistently score above national averages, so a score that looks strong nationally may be closer to average among Mercy's actual applicants. A Battery Composite at the 80th–85th percentile, combined with a 3.5+ GPA and a strong teacher recommendation, makes a compelling application. Merit scholarship consideration typically requires scores at the higher end of that range.
Q: Can my daughter retake the HSPT if she is unhappy with her score?
A: No — the HSPT allows only one attempt per admissions cycle. All scores from every administration where your daughter tested are reported to every school in the network where she applied. That means testing at multiple schools does not give her a way to hide a weaker score. Thorough preparation before December is the only real lever you have. Treat the single December date as your one opportunity and build the prep plan around it from August onward.
Q: Does my daughter need to take the HSPT at Mercy's campus, or can she test at another Catholic high school?
A: Mercy accepts scores from any participating school in the Archdiocese of San Francisco network. However, only students who test on Mercy's campus on the designated December date — December 6, 2025 for the Class of 2030 cycle — are eligible for Mercy's academic merit scholarships. Testing at another school is valid for admission consideration but permanently removes scholarship eligibility for that cycle. Unless a genuine scheduling conflict makes Mercy's campus date impossible, testing at Mercy in December is the right choice for nearly every applicant.
Q: How heavily does the HSPT score weigh compared to GPA and recommendations?
A: Mercy uses holistic review, and no factor carries a publicly stated fixed percentage. Middle school transcripts from grades 6–8, teacher recommendations, application essays, and Shadow Day participation all contribute alongside the HSPT score. In practice, the HSPT carries significant weight because it is the only standardized, objective data point in the file — it gives the committee a common scale across applicants from different middle schools with different grading cultures. It also directly determines merit scholarship eligibility, which makes it doubly important for families managing tuition costs.
Q: Is the Shadow Day truly required, and how do we schedule it?
A: Yes — it is a mandatory component of the Mercy application, not interchangeable with an informational tour. Schedule through Mercy's admissions office starting in September. Popular dates fill within weeks of opening. Your daughter should arrive knowing something specific about Mercy's STEM Pathways Program and the school's Mercy mission, with a few genuine questions to ask her student host. The visit is a chance to show real interest, not just check a box.
Q: Does Mercy offer extended time accommodations for students with a 504 Plan or IEP?
A: Yes — through the AMES program, Mercy extends testing time for students with an active IEP, 504 Plan, or a qualifying professional psychoeducational evaluation. The documentation deadline is the Early Bird deadline in late November, not the general January deadline. Families who miss the AMES deadline cannot receive accommodations retroactively for the December test. Contact Mercy's admissions office before September to confirm accepted documentation formats and the AMES submission process for the current cycle.
Q: When should my daughter start preparing for the Mercy High School Burlingame HSPT?
A: No later than late August or early September — that gives her 14–16 weeks before the December test date. If her middle school offers a spring Pre-HSPT, use that score to identify weak sections and start targeted content review over the summer. Students who begin in June or July have 24+ weeks to build pacing habits, which is the single most consistent factor I see in score improvement on a timed test like the HSPT. Earlier is genuinely better here.
Q: What is the best strategy for the HSPT's fast pace of nearly one question every 30 seconds?
A: Build timed reflexes from the very first week of prep — never practice untimed. The Verbal Skills section runs at about 16 seconds per question; Quantitative Skills at 34 seconds; Language at 25 seconds. Since there is no penalty for wrong answers, your daughter should answer every question, even when guessing at the end. On number series and comparison questions, train her to eliminate two implausible answers in under 10 seconds and commit — extended analysis on a 16-second question burns time she needs for questions she can get right with confidence.
