What are the ILTS exams?

You are interested in becoming an educator in the state of Illinois and discover that ILTS exams are necessary.

Exactly what are ILTS?

The Illinois State Board for Educator Licensure designed the Illinois Licensure Testing System (ILTS) exams to determine a candidate's potential to perform as an entry-level educator in the Illinois public school system.

The ILTS exams are administered on paper and, for selected tests, on computer by the Evaluation Systems group of Pearson. The tests are criterion referenced and objective based. The ILTS exams consist of three tests: the Test of Academic Proficiency (TAP), the Assessment of Professional Teaching (APT), and Content Area Tests.

The Test of Academic Proficiency (TAP) assesses knowledge of fundamental skills in reading comprehension, language arts, math, and writing. The four subtests can be taken at a single session of 5 hours or one subject at a single session for 2 ½ hours. The Reading Comprehension subtest and the Language Arts (grammar and writing) subtest each consist of 60 multiple-choice questions. The Math subtest is made up of 50 multiple-choice items, while the Writing subtest is one constructed-response assignment. A candidate must pass all subtests in order to pass the TAP.

The Assessment of Professional Teaching (APT) assesses professional and pedagogical knowledge. Four hours and 15 minutes are given for 120 multiple-choice questions and 2 constructed-response assignments.

The Content Area Tests assess knowledge of content in the specific field in which licensure is desired. Most Content Area Tests are 3 hours and 15 minutes with 100 multiple-choice questions or 3 hours and 45 minutes with 125 multiple-choice questions. Exceptions can be found at the ILTS website at along with more specific content frameworks for each of the exams.

ILTS scores are available on the ILTS website on the specified score report dates or by email if requested during online registration. All scores are scaled in the 100 – 300 range with a minimum score of 240 required to pass.
