Ron Unz is wrong when he states that "Bilingual education programs fail our students," (Aug 5). Contrary to Unz' claim, the passage of Proposition 227 in 1998, which dismantled bilingual education, did not result in better English proficiency.
It is true that English learners' Stanford 9 scores went up after 227 passed, but so did scores of all students and subgroups in California. A new version of the test was introduced the year before the English-only law was passed. Scores increased each year as students and teachers became more familiar with the test, a well-documented pattern when new standardized tests are introduced. Careful scientific studies have shown no obvious improvement in English language development resulting from the passage of Prop. 227.
Also, experimental studies consistently show that students in bilingual programs outperform comparison students in all-English programs on tests of English reading.
