This report describes the value-added models (VAMs) created for the Pittsburgh Public Schools and the Pittsburgh Federation of Teachers. Pittsburgh's VAMs use not only state assessments but also course-specific assessments, student attendance, and course completion rates, aiming to produce...

Using data on elementary and middle school math and reading outcomes for Pennsylvania students, this working paper found that school value-added provides little useful information for comparing the general leadership skills of different principals when these comparisons include some principals...

This working paper examines the sensitivity and precision of teacher value-added model (VAM) estimates obtained under model specifications that differ based on whether they include student-level background characteristics, peer-level background characteristics, and/or a double-lagged achievement...

Many studies examine the importance of teachers in students' learning, but few exist on the contribution of principals. We measure the effect of principals on gains in primary test scores in North Carolina and estimate the standard deviation of principals' value added to be 0.12 -0.17. We find...

Laws on age at school entry affect student achievement and often change for a number of reasons. Older students are more mature and ready to learn. This can have positive impacts on academic, employment, and earnings outcomes. The costs of holding children back include another year of childcare...

There is a widely held belief that older students, by virtue of being more mature and readier to learn at school entry, may have better academic, employment, and earnings outcomes compared to their younger counterparts. There are understated, albeit important, costs to starting school later,...

We examine the impact of offering full-day as a replacement for half-day kindergarten on mothers' labour supply using the rollout of full-day kindergarten in Ontario, Canada. We find no impact on the extensive margin but do find one on the intensive margin. In particular, we find that access to...

Full-day kindergarten programs are expanding across North America, driven by a policy focus on early childhood development. These programs also affect parents' budget sets and may lead to changes in labour market outcomes. We exploit the unusual nature of Ontario's government school system to...
