The Test for Admission into Catholic High School (TACHS), created by Riverside Insights, is used in and around New York City by Catholic high schools to assess prospective students’ written expression, reading, math, and spatial reasoning skills. The test is administered to 8th graders on the first weekend in November. 


For many students, this is their first time navigating the competitive standardized test landscape. Few are prepared for the rigor, self-discipline, and endurance it takes to achieve an ideal score.


We are here to demystify this process and help your child take charge of their learning!

The TACHS' Format

*please note the lack of questions and allotted time per section. Riverside Insights does not provide this information, nor do they provide a practice test.

Reading Comprehension

The Reading comprehension section is standard for a standardized test, including short literary, historical, social science, and science passages. Questions test a student’s ability to notice main ideas, specific details, vocabulary in context, and inferences. 

Written Expression

The Written comprehension used to test spelling, but this has been eliminated in recent years. It now focuses on grammar rules, including punctuation, capitalization, and subject-verb agreement.


The math section isn’t too advanced for 8th graders and focuses primarily on the foundations: fractions, decimals, percents, operations, ratios/proportions, sequences, basic graphs and tables, and word problems.


The Ability section is the hardest and most unique section of the test. Students are required to find and replicate patterns that are not always obvious. Luckily, it’s incredibly teachable!

Our personalized approach and experienced expert tutors can help your child achieve dramatic score increases quickly (provided your child completes the homework we assign!).

Even if your child already gets in-class instruction on the TACHS as part of their exmissions process at their k-8 Catholic school, one-one-one tutoring can give them a competitive edge and address their specific needs in order to get them into the 90th+ percentile range. 

By working with us and studying for this test, your child will see improvement in their school grades, study habits, and confidence.

When should my child start studying for the TACHS?

For the best outcome with the least amount of stress, we recommend starting in March or April of the year your child is taking the test. This will give us 7-8 months ​to prepare for the test.

What scores does my child need in order to be competitive for their first-choice high school?

This depends on the schools that the child is interested in. Please reach out via our Contact form and Remy will set up a free phone consultation.


When will my child take the TACHS?

A student can only take the TACHS once, so it's important that they do well on their first try.

Where will my child take the TACHS?

Your child will take the TACHS online at home on their laptop, which is great because this is where they'll have been studying! Research shows that students perform better when they study in the same way that they test.


Which materials do you recommend using?

Please visit our Books and Tools page to see which materials we use to prepare our students for the TACHS.

What about the HSPT?

The High School Placement Test (HSPT) is also used in Catholic High School admissions and tests similar topics to the TACHS. However, the amount of time per question -- 24-42 seconds, depending on the section -- is shorter than that of the TACHS. The HSPT is used as a merit scholarship exam by many Catholic schools.


Please visit our HSPT page to learn more about whether or not the HSPT might be a better fit or an additional appropriate test for your child.

Can you help my child prepare for the Marymount Butler Test?

Yes, we can! We have helped many girls prepare for the Butler Scholarship Exam. It's very similar in format and scope to the TACHS and HSPT, so by preparing for these exams, your daughter will be prepared for Marymount's test.
