In this report, Christopher Jepsen and Shelley de Alth conclude that there are numerous obstacles to students being reclassified from English learners to Fluent English Proficient. To start with, over 50 languages are spoken in California's public schools. Although 85 percent of English learners speak Spanish as their first language, the sheer number of other languages complicates matters for specific students and teachers in any given setting. Add to this the mobility of families and movement in and out of schools, and the tendency of many students to drop out of school increases with grade level.
