How Does the New PreACT 9 Compare to the HSPT and ISEE?
The announcement that Chicago Public Schools has replaced the CPS HSAT with the PreACT 9 for Selective Enrollment High School admissions marks a big change to the city's high school application process. Although all three exams are designed to assess a student's academic readiness for high school, they were created for different school systems and each has its own structure, format, and testing philosophy. Understanding where the exams overlap, and where they differ, can help families prepare more efficiently.
Overall, like the HSPT and ISEE, the PreACT 9 is designed to measure a student's overall academic readiness through multiple sections rather than focusing primarily on math and reading as the old CPS HSAT did. Students will now complete Math, Reading, English, and Science sections over approximately two and a half hours, making the exam much more comparable in length and scope to the HSPT and ISEE.
While the tests have more in common with each other than with the old CPS HSAT, there are still differences in format, structure, and content. The PreACT 9 consists of four sections: Math, Reading, English, and Science. Students complete the exam digitally in approximately two and a half hours, are permitted calculators on the Math section, and receive no guessing penalty. The HSPT is organized somewhat differently, as it includes five multiple-choice sections: Verbal Skills, Quantitative Reasoning, Reading, Math, and Language. The HSPT is administered using paper and pencil, calculators are not allowed, and students receive very little time per question, making pacing one of the biggest challenges on the exam. The ISEE similarrly contains five sections, including Verbal Reasoning, Quantitative Reasoning, Reading Comprehension, Math, and an optional essay. Unlike the HSPT, students may take the ISEE once per testing season, giving families more flexibility when scheduling the exam. Schools may administer the ISEE digitally or on paper, but calculators are not permitted.
Despite these structural differences, the exams test many of the same core academic skills. All three include substantial reading comprehension and math components designed to measure middle school academic readiness. Students are expected to analyze passages, solve multi-step math problems, think logically, and work efficiently under timed conditions. Regardless of which exam a student is taking, strong reading, careful reasoning, and solid math knowledge foundations remain essential.
The English and language components illustrate both the similarities and differences among the exams. The HSPT's Language section focuses on grammar, punctuation, capitalization, spelling, and composition through standalone multiple-choice questions. The PreACT 9 also evaluates grammar and writing skills, but it does so through ACT-style editing passages in which students choose the best revisions for sentences and paragraphs. Instead of simply identifying grammar rules, students must consider clarity, organization, style, and rhetorical effectiveness within the context of a longer passage. The ISEE, on the other hand, approaches language somewhat differently. Rather than including a dedicated grammar section, it places greater emphasis on vocabulary through Verbal Reasoning questions involving synonyms and sentence completion. Students with strong vocabularies often have an advantage on the ISEE, while students taking the PreACT 9 may spend more time applying grammar and writing conventions in context.
The reasoning sections also distinguish the exams from one another. Both the HSPT and ISEE include separate quantitative reasoning sections that combine math with logic and pattern recognition. Students encounter number series, comparisons, and reasoning-based problems that extend beyond straightforward math problems and calculations. The PreACT 9 does not include a standalone reasoning section; instead, reasoning is integrated directly into the Math portion of the exam alongside algebra, geometry, functions, statistics, probability, and other grade-level math concepts.
Perhaps the most significant difference is the Science section, which appears only on the PreACT 9. For many families, this initially sounds like the biggest obstacle, but the section is somewhat different from a traditional science test. Students are presented with graphs, tables, experimental results, and scientific scenarios, then asked to interpret data, evaluate investigations, and draw logical conclusions. The emphasis is on scientific reasoning and data analysis rather than memorizing scientific facts, formulas, or vocabulary.
Timing is another important consideration. Although all three exams require students to work efficiently, they do so in different ways. The HSPT is known for its exceptionally fast pacing, with students often having well under a minute, and sometimes only seconds, to answer each question. The ISEE generally provides more time per question for students, while the PreACT 9 falls somewhere in between depending on the section. The English section of the PreACT 9 is particularly fast-paced, while the Math, Reading, and Science sections allow students slightly more time to analyze each problem.
Families should also keep in mind that preparing for one exam does not automatically prepare a student for another. A student applying to CPS selective enrollment high schools and Catholic high schools will likely need to prepare for both the PreACT 9 and the HSPT. Likewise, students applying to independent schools will still need to take the ISEE, even if they are also applying to selective enrollment high schools. However, preparation is far from independent. Improving reading comprehension, strengthening math skills, developing vocabulary, mastering grammar, and learning effective pacing strategies all benefit students across multiple exams.
Overall each exam is designed for a different school system. Students applying to multiple types of schools will need to take more than one exam, which is why it is important for families to understand which test each school requires and what differentiates them before beginning the admissions process. Though there is some overlap in terms of content, preparing for these exams presents different challenges. Test Prep Chicago can help your student prepare for any combination of exams that they plan to take. With the end of the school year just around the corner, now is the right time to get started!

Students can also sign up for individual tutoring for any combination of HSEEs here.
7 Test-Taking Strategies for Success on the PreACT 9
The PreACT 9 is a new factor for eighth-grade students applying to CPS Selective Enrollment High Schools. While a strong understanding of the academic content is essential, knowing how to approach the test can be just as important. The PreACT 9 is designed to measure what students have learned over time in classroom settings; that said, learning effective test-taking strategies that are specific to the PreACT 9, which are not always taught in schools, can help students demonstrate their knowledge and go into the exam with more confidence. By preparing not only what to study but also how to take this specific test, students can approach exam day with greater confidence.
1. Pace Yourself Throughout the Test
One of the biggest challenges students face is managing time. Every section of the PreACT 9 is timed, and it is easy to spend too long on a difficult question without even realizing it. Instead of trying to solve every problem perfectly on the first attempt, students should keep a steady pace. If a question seems especially challenging, it is often better to make the best possible choice and move forward (making a note to come back to it if there is time at the end) rather than risk running out of time.
This strategy is especially important for all four sections of the PreACT 9 because all four require students to balance accuracy with speed.
2. Read Every Question Carefully
Many students miss a question because they misread it, answering an invented question rather than the one that is actually being asked. Paying close attention to words such as "except," "not," "best," or "most likely" can prevent simple mistakes. Reading every answer choice before making a selection also helps students avoid choosing an option that seems correct before finding a better answer later in the list. It’s important to note that, particularly on the English and Reading sections, there may be two answers that are technically correct, but students should look for the best answer overall.
This strategy is particularly valuable in the English and Reading sections, where careful attention to wording is essential. That said, is also useful in the Math and Science sections when interpreting multi-step problems or analyzing data.
3. Use the Process of Elimination
When sunsure of the correct answer, eliminating choices that are clearly incorrect can greatly improve the odds of selecting the right one. Instead of viewing a difficult question as all or nothing and making a random guess, narrowing the possibilities allows students to make a more informed, educated guess. This strategy is especially effective because the PreACT 9 does not penalize students for incorrect answers, so every question should receive a response (even if it’s a guess).
The process of elimination can be applied to every section of the exam.
4. Answer Every Question
On that note, since there is no penalty for guessing, leaving questions unanswered only reduces the opportunity to earn points. If time is running short or a question seems especially difficult, students should eliminate any obviously incorrect answers and make their best educated guess. Even when confidence is low, a thoughtful guess always provides a better chance of earning points than no answer at all.
This strategy applies to every section of the PreACT 9.
5. Focus on Evidence Instead of Prior Knowledge
Some students assume they already know the answer based on what they have learned in class, but the PreACT 9 is designed to measure how well students can analyze the information provided in the question. Note that no outside information is required to succeed on the PreACT 9; while it may come in handy, relying on it too much can actually hinder rather than help a student. In the Reading section, answers should be supported by the passage rather than personal opinions or outside knowledge. Similarly, the Science section emphasizes interpreting graphs, charts, tables, and experimental results rather than recalling advanced scientific facts.
This strategy is most important in the Reading and Science sections, where the correct answer is usually found by carefully examining the information presented on the page.
6. Stay Calm When You Encounter Difficult Questions
Many students struggle with test anxiety, but even students who don’t will come across questions that seem unfamiliar or especially challenging. Strong test takers understand and can quickly internalize that one difficult question does not determine their overall score. Instead of becoming frustrated, they maintain their focus, continue working through the exam, and return their attention to questions they can answer confidently. Remaining calm helps students think more clearly and avoid mistakes caused by rushing or anxiety. This strategy takes practice, as nervousness around an important exam is nervous; that said, it is possible to help a student develop calming techniques to keep their head in the game.
This strategy benefits students throughout the entire exam and is especially helpful during the Math and Science sections, where difficult questions can sometimes interrupt a student's momentum.
7. Prepare Yourself Before Test Day
Successful testing begins before students ever enter the testing room. Getting enough sleep, eating a healthy breakfast, and arriving prepared with any required materials (scratch paper, extra pencils, water, snacks, calculator) can improve concentration and reduce unnecessary stress. Students should also complete practice tests under timed conditions before the exam so they can become comfortable with the pacing and format. Familiarity with the testing experience helps reduce anxiety and allows students to focus on demonstrating what they know.
This preparation supports success across every section of the PreACT 9 and helps students perform at their highest level from the first question to the last.

Breaking Down the Four Sections on the PreACT 9
Recently, it was announced that Chicago Public Schools has replaced the CPS HSAT with the PreACT 9 Secure, a nationally recognized assessment that is now being administered to rising Chicago 8th-graders as part of the Selective Enrollment High School admissions process.
The change represents far more than a simple name swap. The PreACT 9 is a fundamentally different type of exam. While the CPS HSAT was built specifically for CPS admissions, the PreACT 9 was created to measure academic readiness and predict future success on the ACT, the college entrance exam many students take during high school. As a result, families are encountering a test that is longer, more comprehensive, and more closely aligned with the skills students will need throughout high school and beyond.
One of the first things families notice about the PreACT 9 is its length. The exam includes four separate sections (English, Math, Reading, and Science) and requires students to maintain concentration for two and a hours. Success on the exam depends not only on academic ability, but also on a student's capacity to stay focused and work efficiently over an extended period of time. Here is a breakdown of each of the sections seen on the PreACT 9:
The English section focuses on grammar, sentence structure, punctuation, usage, and writing effectiveness. Students are presented with passages and asked to identify the best revisions, correct grammatical errors, improve sentence flow, and strengthen organization. Questions frequently require students to understand comma usage, subject-verb agreement, sentence boundaries, transitions, and word choice. Students are tested on writing production (27-33% of questions), language knowledge (12-18% of questions), and English conventions (48-55% of questions), and students are given 35 minutes to answer 44 questions.
The Math section combines computational skills with higher-level reasoning. Students encounter questions involving algebra, geometry, ratios, proportions, statistics, and data analysis. Students must analyze information, interpret graphs, and choose efficient solution strategies while managing strict time limits. Students are tested on the real number system (10-13% of questions), algebra (20-27% of questions), functions (20-27% of questions), geometry (10-13% of questions), and statistics/probability (10-13%), and are given 45 minutes to answer 35 questions.
The Reading section involves reading passages drawn from literature, social studies, humanities, and science before answering questions that assess comprehension and analytical thinking. Rather than focusing solely on straightforward details, many questions require students to infer meaning, identify an author's purpose, evaluate tone, and determine how evidence supports an argument. The challenge lies in balancing speed with accuracy; students must process substantial amounts of information without sacrificing careful analysis. Students are tested on key ideas and details (52-60% of questions), craft and structure (28-36% of questions), and integration of knowledge and ideas (12-16% of questions), and are given 40 minutes to answer 33 questions.
For the Science section, many students enter the test expecting questions that emphasize memorized scientific facts, formulas, or vocabulary. Instead, the Science section is largely an exercise in data interpretation and reasoning. Students are presented with science-oriented reading passages, graphs, charts, experimental results, and research summaries. They must identify trends, evaluate conclusions, compare experimental designs, and draw logical inferences from evidence. In many cases, prior scientific knowledge plays a smaller role than the ability to analyze information quickly and accurately. Students who are comfortable reading tables and scientific passages, as well as interpreting visual data often perform well, even if they do not consider science to be their strongest subject. Students are tested on interpretation of data (23-50%), scientific investigation (15-35% of questions), and evaluation of models, inferences, and experiments (19-38% of questions), and are given 35 minutes to answer 32 questions.
Beyond the test itself, one of the most significant features of the PreACT 9 is the detailed score report students receive afterward. Unlike many admissions exams that provide only a single score, the PreACT 9 offers a comprehensive breakdown of performance across multiple areas. Students receive individual scores for English, Math, Reading, and Science, along with an overall composite score that reflects their performance across the entire assessment. This allows families to see where students excel and where additional support may be needed.

CPS Announces “PreACT 9 Secure” as New CPS High School Entrance Exam
Yesterday, CPS announced to school leaders that, beginning this fall, the CPS HSAT test will be replaced by a new exam, the PreACT 9 Secure. This test will be the new exam used for the GoCPS high school admissions process, and will be offered to all 8th-grade students.
Overall, students can expect the following changes when taking the new exam:
The PreACT 9 Secure is a longer test than the CPS HSAT. The CPS HSAT lasted one hour, while the PreACT 9 Secure will last approximately two and a half hours.
The PreACT 9 Secure includes 4 sections, while the CPS HSAT only included 2. The CPS HSAT had a 30-minute Math section and a 30-minute Reading section; the PreACT 9 Secure will have a 35-minute ELA section, a 40-minute Reading section, a 45-minute Math section, and a 35-minute Science section.
The PreACT 9 Secure will only be available in English, though it will still have accommodations for ESL students. The CPS HSAT had been available in multiple languages, but the PreACT 9 Secure will not have this option available.
CPS has cited the following reasons for this adjustment:
The PreACT 9 Secure provides more information to high school staff on students entering their 9th-grade course. As the PreACT 9 Secure has four sections (Math, Reading, ELA, and Science) and tests more skills than the CPS HSAT, it can be used for more than just admissions, providing high schools with meaningful information on student performance that can lead to course placement and programming decisions.
The PreACT 9 Secure aligns with the ACT. This will help students gain experience with the structure of the ACT, which they will take later in high school. CPS now administers the ACT to all CPS high school students.
The PreACT 9 Secure has more publicly available information and content. The CPS HSAT did not have information publicly available regarding length, sections included, and content. The PreACT 9 Secure is a test used across the country, meaning that students will now have more access to information about what to expect on the exam. Additionally, because the exam is widely used, there will be greater access to free or low-cost test prep resources.
The PreACT 9 Secure is a tested, stable platform. In the past, students encountered multiple issues with the platform used for the CPS HSAT. The PreACT platform has stronger, more stable technology and security.
