Laczko-Kerr, I., & Berliner, D. C. (2002, September 6). The Effectiveness of "Teach for America" and Other Under-certified Teachers on Student Academic Achievement: A Case of Harmful Public Policy. Education Policy Analysis Archives, 10(37). http://epaa.asu.edu/epaa/v10n37/

q2 · i? · causal · r?

From the same matched-pair study of 109 teacher pairs in five low-income Arizona districts, comparing annual academic growth of students of under-certified versus regularly certified teachers. The printed magnitude is a percentage of growth per year, not a standardized effect size, so no standardized impact is coded.

"Students of under-certified teachers make about 20% less academic growth per year than do students of teachers with regular certification."
