The State Seal of Biliteracy (SSB), marked by a gold seal on the diploma or transcript, recognizes high school graduates who have attained a high level of proficiency in speaking, reading, and writing one or more languages in addition to English.

Riverside County Office of Education is dedicated to supporting all Riverside County students with meeting the language proficiency requirements for the California State Seal of Biliteracy. K-12 districts may request, following the RCOE Timeline, free language assessments in over 40 different languages.
