Substituting English immersion for bilingual education is not working well

Stephen Krashen - Guest Opinion

Regarding the March 28 online column “California’s English learners: Can you say ‘Held back’?” Kelly Torrance feels that the increase of English learners scoring in the two highest levels of the California English Language Development Test (CELDT) shows that dismantling bilingual education (Proposition 227) worked. But these increases appear to have nothing to do with real improvement.

This January, the California Legislative Analyst’s Office reported that at least some of the increase in the percentage of students at the top two CELDT levels was because of a traffic jam: Many children in these levels have been there for several years; the percentage of those moving into the advanced levels has actually decreased.

The overall progress of children in California under English immersion is actually very slow; average gains are less than one level of the CELDT per year, out of five levels, where level five means “ready for the mainstream.” Also, an analysis done by the American Institutes for Research and WestEd showed that substituting English immersion for bilingual education has not accelerated the English development of California’s English learners.
