Seal of Biliteracy

GBN is proud to offer the State Seal of Biliteracy to qualifying students who demonstrate a high level of proficiency in English as well as another language. 

What is the Seal of Biliteracy?

The State Seal is an award given to high school graduates that appears as a seal on their diploma and is included on the official transcript 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 in addition to English at the Intermediate High level of proficiency.

Why is the State Seal of Biliteracy valuable?

Benefits of this recognition include, but are not limited to:

  • distinguishing one’s resume and college application (Article: “Learning a Foreign Language helps kids think and make money”); 
  • sharing one’s proficiency level for scholarship & career opportunities; 
  • earning college credit; Illinois law requires Illinois state universities to award credit; 
  • understanding one’s proficiency level in order to set advanced language goals; 
  • speaking more than one language improves cognitive function across the board, from planning and working memory to concentration and multitasking. (Source: New Scientist)
