The program is based on studies of immersion education and the five principles outlined in the Theoretical Framework for Bilingual Education published by the California State Department of Education. The program started in the early 1980s. The program is based on research revealing that students' development in a second language is determined by their development in their first language. By fifth grade, students are expected to be able to handle the complete curriculum in both their primary and secondary languages. At this point, the curriculum is taught completely on an alternating basis.
Teachers use voice intonations, gestures, manipulatives, and visual aids to teach concepts.
Over 785 students, or approximately 30 percent of the district's total student population, participate in the Valley Center Bilingual Education Program from kindergarten through eighth grade. In 1997, there were 43 bilingual teachers. Of this group, all but four possess a bilingual teaching credential, and the others possess CLAD certification and work in a team with bilingual teachers. Over 95 percent of all EL students are Spanish speaking. Most SL students may enter the program without addition preparation up through second grade.
