The TACHS ability section is the part of the Catholic high school admissions exam that almost every 8th grader walks into completely cold. It covers figure matrices, paper folding, and figure classification — skills no teacher has ever assigned for homework. I've seen students with a 90th percentile in Math stumble on the Ability section. They weren't unprepared students. They just didn't know this section was something you could actually study. This guide gives you what you need to change that before November.

What the TACHS Ability Section Tests — and Why It Catches Smart Students Off Guard
The TACHS ability section spans approximately 50 questions completed in about 32 minutes. It contains three distinct question types.
Figure Matrices ask your child to identify the missing piece that completes a visual pattern grid — essentially a visual analogy. Paper Folding (also called Hole-Punch) questions show a sheet of paper being folded and punched, and your child must identify where the holes land when the paper is unfolded. Figure Classification presents three shapes that share a hidden rule, and your child must choose a fourth shape that belongs to the same group.
None of these appear in any standard 7th or 8th grade curriculum. There is no class called "spatial reasoning." Your child's teacher has never assigned paper folding as homework. That's exactly why the Ability section catches high-achieving students off guard — years of strong academic preparation simply do not transfer to these question types.
The Ability section also receives its own separate percentile score. Catholic high schools see your child's Ability percentile alongside Math and Reading percentiles. A weak Ability score pulls down a strong overall profile. A strong Ability score — especially at the 85th percentile or above — can unlock honors-track placement and merit scholarship consideration even when other section scores are solid but not exceptional.
Prep Tip — Start Earlier Than You Think: The TACHS can only be taken once per cycle. There are no retakes. If your child is currently in 7th grade, starting TACHS ability section practice now puts them a full year ahead of most applicants. Most families don't begin prep until September of 8th grade — leaving only 6–8 weeks before the November test date.
TACHS Spatial Reasoning Is a Trainable Skill — Here's What the Research Actually Shows
Many parents assume the Ability section measures fixed, innate intelligence — something you either have or don't. That assumption is wrong, and it costs students scholarship dollars and honors placements every year.
Research in cognitive psychology shows that visual-spatial reasoning responds directly to deliberate practice. Studies published in journals including Psychological Science and Intelligence have documented meaningful gains in spatial reasoning after as few as 10–20 hours of structured practice. What's happening isn't mysterious — the brain learns to recognize patterns faster by building perceptual shortcuts. The more times your child sees a paper folding problem, the faster they can mentally simulate the folds. That's not a fixed trait. That's a trained skill.
For TACHS ability section practice, this means three specific things. First, exposure matters — your child needs to see Figure Matrices, Paper Folding, and Figure Classification problems repeatedly, not just once. Second, timed practice matters — the Ability section allows roughly 38 seconds per question, so speed and pattern recognition must be trained together. Third, review matters — working through why a wrong answer was wrong builds rule-recognition faster than simply moving to the next problem.
I've watched students add 15 to 20 percentile points to their Ability score over 8 weeks of focused STEM critical thinking practice. That kind of gain is rare in Reading or Math — those sections reward years of academic exposure. The Ability section rewards focused preparation in the months right before the test. That's actually good news for any family starting now.
How to Practice TACHS Figure Matrices, Paper Folding, and Figure Classification
Each of the three Ability question types needs a slightly different mental approach. Building these strategies through TACHS ability section practice — rather than figuring them out for the first time on test day — is the single biggest performance differentiator I've seen.
Figure Matrices: Identify the Rule Before You Look at the Answer Choices
Figure Matrices show a 3×3 or 2×2 grid with one cell missing. Before scanning the answer choices, train your child to ask: "What changes from left to right? What changes from top to bottom?" Changes in size, shading, rotation, and number of elements are the most common rules. Identifying the rule first eliminates the trap of choosing an answer that looks visually similar but breaks the actual pattern.
Paper Folding: Build the Mental Model with Real Paper First
Paper Folding questions typically show 1–3 sequential folds followed by a hole punch. The key skill is mentally "unfolding" the paper in reverse, one step at a time. Have your child practice with real paper and a hole punch — doing this 10 to 15 times physically builds the spatial model faster than any written explanation. Once that physical instinct is in place, the visual question format on screen becomes much easier to decode.
Figure Classification: The Right Answer Usually Hides Behind the Obvious One
Figure Classification shows three example shapes, and your child must find a fourth that belongs with them. The easy traps are color and size — these surface features look like the rule but usually aren't. The actual rule is almost always structural: number of sides, symmetry type, presence of curves, or open versus closed shapes. Train your child to name and then set aside the most obvious feature before looking for a deeper pattern. This habit alone eliminates the most common classification errors I've seen students make.
Prep Tip — Timed Sprints Over Long Sessions: Practice the Ability section in 10-minute timed blocks, not long sittings. Spatial reasoning performance drops with mental fatigue faster than verbal performance does. Short, focused sessions 4–5 days per week build stamina more effectively than one long session once a week.
How TACHS Ability Scores Affect Catholic High School Admissions and Scholarship Placement
Here is the connection most prep resources miss entirely: your child's Ability percentile is not just an admissions number. At many Catholic high schools in the Archdiocese of New York and the Diocese of Brooklyn and Queens, it is a scholarship and academic-track trigger.
Schools like Archbishop Molloy, Cardinal Spellman, Christ the King, Holy Cross, and Bishop Kearney use individual section percentiles — not just the Total Achievement Score — when awarding merit scholarships and placing students into honors, regents, or scholars programs. A student who earns a 92nd percentile Ability score alongside a 78th percentile in Math may still qualify for honors-track placement because the Ability score signals strong reasoning potential.
Specific score thresholds vary by school and are rarely published publicly. Based on patterns I've seen in admissions outcomes over the years, students placed into honors tracks at competitive ADNY and DBQ schools typically score at or above the 75th percentile on the Ability section. Students considered for named merit scholarships at selective schools often score at or above the 88th to 92nd percentile. These are observations, not official figures — contact individual school admissions offices for current benchmarks.
One detail worth knowing: the Total Achievement Score on your child's TACHS reflects Reading, Written Expression, and Mathematics. The Ability section is scored and reported separately. Schools see both. A low Ability percentile does not drag down the Total Achievement Score — but admissions offices see it anyway. Don't let a preventable Ability score gap cost your child a scholarship offer.
TACHS Online Testing in 2026 — What Your Child Needs Ready for the Ability Section and Beyond
The TACHS is fully online with remote proctoring. Your child tests at home — and a tech problem on test day cannot be fixed in the moment. There is one test date per diocese per year and no retakes. Preparing for the online environment is as important as preparing for the content.
Your child needs a desktop computer, laptop, or Chromebook — not a tablet or phone. The device must have a functioning webcam, a microphone, and a stable internet connection. Proctoring software (Proctorio) requires a full camera scan of the testing room before the exam begins. This scan is not optional and takes a few minutes. Do a practice run with your child at least a week before so it's not a stressor on test morning.
Students are randomly assigned to either an 8:30 AM or 10:00 AM session on their diocese-specific test date. You cannot request a preference. Build your child's test-day routine around both possible start times. Have them complete a full timed Ability section practice at 8:30 AM at least twice before November so an early start isn't a physical shock to their system.
High school choice selections must be entered at tachsinfo.com by approximately the night of the exam — for the 2025–26 cycle, that deadline was November 8. If you miss this step, scores cannot be sent to your chosen schools. Add this to your calendar now alongside the registration window: August 24 – October 28, 2026.
Tech Check Tip — Run a Full Dry Run at Least One Week Before Test Day: Open the tachsinfo.com system check page on the exact device your child will use. Confirm the webcam works, the internet speed is stable, and no firewall or content filter blocks the proctoring software. Finding a problem one week out is manageable. Finding it on test morning is not.
TACHS vs. SHSAT — How to Manage TACHS Ability Section Prep When Your Child Is Taking Both Tests
Thousands of NYC 8th graders sit for both the SHSAT and the TACHS in the same fall. The SHSAT is typically administered in late October or early November depending on the year; the TACHS follows in November. This is a compressed, high-stakes calendar, and most families have no clear plan for managing both.
There is meaningful overlap between the two exams. Both reward strong mathematical reasoning and problem-solving. SHSAT Math prep builds number sense and fluency that carries directly into TACHS Mathematics. TACHS Written Expression overlaps with the SHSAT ELA Revising/Editing subsection — grammar, sentence structure, and paragraph logic are tested on both.
The TACHS ability section has no SHSAT equivalent. That's the gap. Students who spend October entirely on SHSAT prep arrive at the November TACHS having done zero Ability practice. The fix is to build TACHS spatial reasoning practice into August and September — before SHSAT crunch time — so the Ability skill is already developed when October arrives.
In my experience, students who treat the two tests as one unified fall prep challenge manage both timelines without burning out. The key is starting TACHS ability section practice in late summer, not in October when SHSAT prep is already peaking.
Frequently Asked Questions: TACHS Ability Section and Catholic High School Admissions (Archdiocese of New York & Diocese of Brooklyn/Queens)
Q: What is the TACHS Ability section and why is it so hard to prepare for?
A: The TACHS Ability section tests abstract reasoning through three question types: Figure Matrices, Paper Folding (hole-punch), and Figure Classification. None of these are taught in any standard middle school curriculum. There is no textbook chapter on spatial pattern recognition — which is exactly why targeted practice with STEM critical thinking tools gives students a measurable edge. Most 8th graders walk into the Ability section having never seen these question formats before test day.
Q: Can you actually improve your TACHS Ability score with practice?
A: Yes — spatial reasoning and pattern recognition are trainable skills, not fixed talents. Research in cognitive psychology shows that repeated exposure to visual-spatial problem sets produces measurable gains, often within 4 to 8 weeks of deliberate practice. Students who complete timed STEM reasoning drills before the November test date consistently score higher on the Ability section than students who focus only on Math and Reading prep. The Ability section is actually where practice pays off fastest.
Q: How much of the TACHS is the Ability section?
A: The Ability section accounts for approximately 50 of the 200 total questions — about 25 percent of the test. It is scored and reported separately from the Total Achievement Score, which covers Reading, Written Expression, and Mathematics. Your child receives both a Local Percentile Rank and a National Percentile Rank for the Ability section alone. High schools see this score independently, so it directly affects admissions decisions and academic track placement regardless of the Total Achievement Score.
Q: My child is great at math and reading — do they still need to prepare for the Ability section?
A: Yes, absolutely. The Ability section uses a completely different cognitive skill set than academic knowledge. Strong students are frequently surprised — and underprepared — because figure matrices and paper folding problems cannot be solved by recalling facts, applying formulas, or using grammar rules. I've seen top students earn an Ability percentile well below their Reading and Math scores simply because they didn't practice this section. That gap can affect both admissions outcomes and honors-track placement at Catholic high schools.
Q: Can my child retake the TACHS if they are unhappy with their score?
A: No. The TACHS can only be taken once per admissions cycle — there is no retake option within the same year. Score reports reach your chosen high schools before students receive their Home Report in late January. This makes thorough preparation before the single November test date especially critical. If a documented emergency prevented your child from testing, contact the TACHS office at tachsinfo.com directly — but approved exceptions are rare and not guaranteed.
Q: Does my child need to attend a Catholic elementary school to take the TACHS?
A: No. Public school students and students from non-Catholic private schools are fully eligible to register for the TACHS and apply to participating Catholic high schools. Public school applicants register directly through tachsinfo.com without a school-submitted Applicant Record. These students often receive less institutional guidance than Catholic school peers, making independent preparation — including TACHS ability section practice and STEM critical thinking drills — especially important for building a competitive application.
Q: How does a TACHS score affect scholarship eligibility at Catholic high schools?
A: Many participating high schools use TACHS section scores — particularly the Ability and Math percentiles — to award merit scholarships and place students into honors or scholars tracks. A student who scores at or above the 85th percentile on the Ability section may qualify for scholarship consideration at schools like Archbishop Molloy, Cardinal Spellman, or Christ the King even without a perfect overall score. Specific thresholds vary by school and are not always published. Contact individual school admissions offices for current benchmarks — this is a call worth making in the fall.
Q: What happens if my child has an IEP or 504 plan — can they get extended time on the TACHS?
A: Accommodations including extended time may be available for students with a current IEP or 504 plan, but requests must be submitted during the registration window — August 24 through October 28, 2026 for the 2026–27 cycle. Documentation must go through tachsinfo.com. Do not wait until October to start this process — August is the right time. Approved accommodations are noted on score reports sent to high schools, which handle accommodation decisions independently.
Build Your TACHS Ability Section Score with Purpose-Built STEM Critical Thinking Practice Tests
The TACHS ability section is where deliberate practice delivers the fastest, most dramatic score gains — and it's the section most students completely ignore. The students I've seen make the biggest jumps aren't the ones who studied harder on Math. They're the ones who spent 8 weeks doing focused, timed spatial reasoning practice before anyone else started paying attention to it.
At stemcriticalthinking.com, our STEM Critical Thinking Practice Tests are built specifically to develop the visual-spatial reasoning, abstract pattern recognition, and logical analysis skills the TACHS Ability section rewards. These aren't generic test prep questions. They're designed to train the exact cognitive skills assessed by Figure Matrices, Paper Folding, and Figure Classification problems.
Every practice test is timed to match the 32-minute Ability section format. Every answer includes a detailed explanation so your child learns the underlying reasoning rule — not just whether they got the answer right. That's the difference between a one-time correct guess and a skill that holds up across every question in the section.
The TACHS registration window opens August 24, 2026. The test is November. There is no retake. Start building this skill now — before the rest of the applicant pool does.
