The Premier Choice for TACHS Prep

The TACHS, or Test for Admission into Catholic High Schools, is given in New York City and a number of other New York counties each year in November to eighth-graders seeking admission to specific Catholic high schools. The high schools use the exam results to make decisions about admitting applicants and to group prospective ninth-grade students into classes. The test measures academic achievement in reading, language arts, and mathematics, and assesses general reasoning skills.

Your Score

You will receive one point for every question that you answer correctly on the TACHs. This is your raw score, which is tallied and then converted to a scaled score according to a formula determined by the test developers. Converting raw scores to scaled scores allows schools to compare a student's performance on one part of the exam with his or her performance on other parts that may have included a greater or lesser number of questions. Finally, scales scores are reported as percentile rank. Percentile rank shows where students stand in relationship to one another on various sections and on the test as a whole.
