This brief explains a new approach that NCTQ is taking for reporting how much leave public school teachers receive in the large school districts that are featured in our Teacher Contract Database. Here we describe the reporting problems that we encountered and how we have resolved those inconsistencies, making it fairer to compare leave benefits across districts. We also show which large districts offer the most leave in the United States and the least. We conclude by examining some of the hidden costs that districts take on when offering many different kinds of leave.
