Iowa Test of Basic Skills (ITBS) Results
Each fall students in first through eighth grade take the ITBS. The ITBS is norm referenced test that is administered throughout the Diocese of Joliet Catholic School as well as in private and public schools nationwide. In short, a norm-referenced test report whether test takers performed better or worse than a hypothetical average student, which is determined by comparing scores against the performance results of a statistically selected group of test takers, typically of the same age or grade level, who have already taken the exam. As such, the 50th percentile is the point where half of all test takers scored above and 50 percent scored below. As you will note in the table below, in all areas tested St. Joan students scored well above the national average.

There were a number of outstanding performances among the three grades that sat for the ITBS. For example, in math, six seventh graders scored in the 99th percentile in the math and 80% of seventh graders scored in the top 20th percentile. In English / Language Arts, 65% of the seventh grade class scored at or above the 90th percentile.
Along with the ITBS, students sat for the Cognitive Abilities Test (CogAT) test. The CogAT is used to measure a student’s general reasoning abilities in the areas of verbal, quantitative, and nonverbal skills. Parents received CogAT results along with the results of the ITBS.
We believe that standardized test results provide a diagnostic tool for helping all students reach their academic potential. They provide the information necessary to adapt instruction to the personal needs of every student. As a school we do not teach to the tests, we learn from them.
