Seal of Biliteracy

According to the Illinois State Board of Education (ISBE), “The State Seal of Biliteracy is a recognition given to graduating high school students who have demonstrated a high level of proficiency in English and in reading, writing, listening and speaking in another language.”

Two levels of recognition are awarded, and the level achieved by a student is determined by that student’s performance on a state-approved standardized assessment to measure English proficiency and proficiency in a foreign language. The two levels are:

  1. State Seal of Biliteracy
  2. State Commendation toward Biliteracy

The State Seal of Biliteracy and Commendation are placed on the student’s diploma and transcript as an official credential certified by ISBE. State colleges and universities have the option to accept the State Seal of Biliteracy for college credit.

To be eligible for the Seal of Biliteracy/Commendation program, students must have been enrolled in Advanced Placement (AP)/college-level or Honors language courses and/or participated in the English Learner (EL) program. Additional student requests to participate in the program may be presented to the Addison Trail or Willowbrook Literacy and World Language Department Chairpersons. Qualifying students will take the required assessment in English or another language during the testing window of Feb. 21 through March 1, 2020.
