Seal of Biliteracy


Oak Lawn Community High School is proud to offer the Illinois State Seal of Biliteracy to qualifying OLCHS students who demonstrate a high level of proficiency in one or more languages in addition to English.  

The Seal of Biliteracy is awarded to those who demonstrate proficiency in English and whose second language proficiency level is equivalent to Intermediate-High, as determined by the American Council on the Teaching of Foreign Languages (ACTFL).

The State Seal is an award given to high school seniors that appears as a seal on their diplomas and official transcripts to certify that the student is biliterate in English and one or more languages. A biliterate person can read, write, speak, and understand another language.

The benefits to achieving this honor include:

• Earning college credit in Illinois and possibly other states
• Distinguishing your resume and college application
• Earning scholarship and career opportunities
• Understanding your proficiency to set advanced language goals

To qualify for the Seal of Biliteracy students must demonstrate proficiency in:

English by earning a minimum score of 540 on the Evidence-Based Reading and Writing portion of the SAT (or other approved measure).

Foreign Language by earning a minimum score of I-5 on the AAPPL (ACTFL’s Assessment of Performance Toward Proficiency in Languages) Exam (or other approved measure).

In 2019 seventeen members of the Class of 2019 earned a Seal of Biliteracy in Spanish, Arabic, or Polish.  One additional student earned the Seal of Biliteracy in both Spanish and Polish!
