Panel or grouped data are often used to allow for unobserved individual heterogeneity in econometric models via fixed effects. In this paper, we discuss identification of a panel data model in which the unobserved heterogeneity both enters additively and interacts with treatment variables. We present identification and estimation methods for…

In our 2019 annual report, we provide insight into our sponsorship work during the year and the performance of our sponsored schools. We are also pleased to highlight the good work of our colleagues on Fordham's policy and research teams. Our schools' academic performance shows several schools doing very well on Ohio's value added (growth) measure…

The 2017-18 school year saw our sponsorship portfolio grow from 4,100 students in 2016-17 to 4,800 students across five Ohio cities: Dayton, Columbus, Cincinnati, Cleveland, and Portsmouth.

In this quantitative study, the effects that the NCLB act has had on students' opportunity to learn (OTL) and Subject Level Success (SS) from 2004 to 2012 in 9th, 10th, and 11th grade math coursework (Algebra 1, Geometry, Algebra 2, and…

The 2015-16 school year was one of transition in Ohio. New state assessments (again), new charter sponsor evaluations, and even a new state superintendent. Change is hard, but it is important to remember that the developments of the last twelve months have their roots in policy decisions designed to improve Ohio's academic standards overall and…

NCLB policies in the United States focus schools' efforts on implementing effective instructional processes to improve student outcomes. This study looks more specifically at how schools are perceived to be implementing state required curricula and benchmarks and developing teaching and learning processes that support the teaching of state…

There is often confusion about distinctions between growth models and value-added models. The first half of this paper attempts to dispel some of these confusions by clarifying terminology and illustrating by example how the results from a large-scale assessment can and will be used to make inferences about student growth and the value-added…

In this report, the authors describe the value-added models used as part of teacher evaluation systems in the District of Columbia Public Schools (DCPS) and in eligible DC charter schools participating in Race to the Top. They estimated (1) teacher effectiveness in DCPS and eligible DC charter schools during the 2011-2012 school year; and (2)…
