A growing number of states and school districts are promoting bilingualism by offering special recognition for high school graduates who demonstrate fluency in languages other than English.

Thirteen states now offer a "seal of biliteracy," and at least 10 more are working toward implementing a similar award. Students in nine of the nation's 10 largest school systems can earn statewide or district-level recognition with the seal affixed to their diplomas or transcripts as official proof that they can speak, read, and write in more than one language.
