Private high school practice tests help eighth graders prepare for the two exams most private and Catholic high schools use for admission: the High School Placement Test (HSPT) and the Test for Admission into Catholic High Schools (TACHS). Practice tests prepare students by building familiarity with the real exam format, strengthening the specific verbal, quantitative, reading, math, and language skills each test measures, and reducing test-day anxiety through realistic, repeated practice. Students get only one attempt at either exam, so walking in prepared matters. Here is exactly what these practice tests help with, and when to start using them.
What Are the HSPT and TACHS, and Why Do They Matter?
Scholastic Testing Service (STS) publishes and administers the HSPT, and many Catholic and private high schools require it for incoming eighth graders. It covers five sections: Verbal Skills, Quantitative Skills, Reading, Mathematics, and Language. Schools use the results for admission decisions, scholarship selection, and course placement.
The TACHS serves the same purpose for Catholic high schools in the Archdiocese of New York, the Diocese of Brooklyn/Queens, and the Diocese of Rockville Centre. The TACHS measures aptitude and achievement in reading, mathematics, and language, and is administered as a remote online exam each fall to eighth graders applying for admission the following school year. In 2026, the Archdiocese of New York gives the TACHS on November 6, and the Diocese of Brooklyn/Queens and Diocese of Rockville Centre give it on November 7.
Students can take the HSPT and TACHS only once; they cannot retake them if their first attempt does not reflect their true ability. Both exams carry real weight for a student’s high school placement, which is exactly why HSPT practice test and TACHS practice test preparation is an essential piece of preparedness, rather than an optional extra.
How Private High School Practice Tests Build Familiarity With the Real Exam Format
A full-length HSPT practice test or TACHS practice test does more than review content. It reproduces the section order, time limits, and question style a student will see on test day, so nothing about the format feels unfamiliar. Students learn what a Verbal Skills section looks like next to a Quantitative Skills section, how a Reading passage is followed by its questions, and how much time they realistically have per section.
This kind of format familiarity matters because both exams are timed tightly enough that pacing is part of the challenge. A student who has never practiced under real time pressure often runs out of time on sections they could otherwise answer correctly, not because they lack the skill, but because they have not built a feel for the pace the test demands.
What Skills Do HSPT and TACHS Practice Tests Actually Strengthen?
Private high school practice tests target the specific skills each exam scores. On the HSPT, that means vocabulary and verbal reasoning for the Verbal Skills section; sequences and comparisons for Quantitative Skills; comprehension and inference for Reading; computation and problem-solving for Mathematics; and grammar and usage for Language. On the TACHS, practice reinforces reading comprehension, math computation, problem-solving, and language mechanics in the same way.
Both exams compare a student’s performance against a national or regional pool of test-takers, so HSPT prep and TACHS prep work best when they meet student gaps. A practice test that shows a student is strong in Mathematics but weak in Verbal Skills lets a family and tutor focus study time where it most affects the score, instead of reviewing everything equally.
How Practice Tests Reduce Test-Day Anxiety and Build Pacing
Repetition changes how a student experiences the real exam. A student who has sat through several full-length practice tests already knows what they can do, the test timing, and what the question flow feels like. With practice tests, the actual Catholic high school entrance exam feels like one more practice run rather than an unfamiliar high-stakes event. That familiarity alone tends to reduce the kind of test-day nerves that cause students to underperform relative to what they actually know.
Timed practice also builds an internal sense of pace. Students start to recognize, without constantly checking the clock, whether they are moving too slowly through a section. They can then adjust in the moment on the real HSPT or TACHS instead of discovering the problem only after time runs out.
When Should a Student Start HSPT and TACHS Prep?
Both exams are given in the fall of eighth grade and can only be taken once; most educators recommend starting HSPT prep and TACHS prep in the spring or summer before eighth grade, well ahead of the November test dates. That timeline gives students months to work through multiple private high school practice tests, review their weakest sections, and build pacing skills gradually instead of cramming in the final days.
HSPT and TACHS Prep: The Bottom Line
The HSPT and TACHS are one-shot exams that carry real weight for where a student lands in high school, so preparation is key. Private high school practice tests, used consistently in the months before the exam, give eighth graders the format familiarity, targeted skill-building, and calm pacing they need to walk into test day ready, not guessing. Whether a family is preparing for an HSPT practice test or a TACHS practice test, starting early with realistic, full-length practice is what turns a stressful one-time exam into a manageable, well-rehearsed one.
