Performance Screens for School Improvement: The Case of Teacher Tenure Reform in New York City

Tenure reforms in NYC led to a substantial drop in the percent of eligible teachers approved for tenure – from 94 percent during academic years 2007-08 and 2008-09, the two years prior to the introduction of the policy, to 89 percent in the first year of the policy (2009-10) and to an average of 56 percent during the three subsequent years.
The vast majority of eligible teachers who were not approved for tenure had their probationary period extended. The proportion of teachers denied tenure changed only slightly, from two to three percent, following reform.
