Most research on the relationship between teacher characteristics and pupil achievement focuses on salaries, experience, and education. The effect of in-service training has received less attention. We estimate the effect of in-service teacher training on achievements in Jerusalem elementary schools using a matched-comparison design. Differences-in-differences, regression, and matching estimates suggest training in secular schools lead to an improvement in test scores. The estimates for religious schools are not clear-cut, perhaps because training religious schools started later and was implemented on a smaller scale. Estimates for secular schools suggest teacher training provided a cost-effective means of increasing test scores. Copyright 2001 by University of Chicago Press.
