Does student-teacher match quality exist? Prior work has documented large disparities in teachers' impacts across student types but has not distinguished between sorting and causal effects as the drivers of these disparities. I propose a disparate value-added model and derive a novel measure of teacher quality--revealed comparative advantage--that…

Student assessment nonparticipation (or opt out) has increased substantially in K-12 schools in states across the country. This increase in opt out has the potential to impact achievement and growth (or value-added) measures used for educator and institutional accountability. In this simulation study, we investigated the extent to which…

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. We're also honored to have been recognized by the National Association for Charter School Authorizers (NACSA) as part of NACSA's Quality Practice Project.…

The Thomas B. Fordham Foundation's sponsorship annual report highlights our work with eleven schools that served 4,150 students in five Ohio cities during the 2016-17 school year. We value this opportunity to keep stakeholders and the public informed about our efforts, and provide information on each of the schools that we sponsor. Additionally,…

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…

The 2015 Fordham Sponsorship Annual Report is our opportunity to share the Fordham Foundation's work as the sponsor of eleven schools serving approximately 3,200 students in five cities, and our related policy work in Ohio and nationally. Charter school policy took a giant leap forward in Ohio in 2015 with the passage of HB 2. The road to a…

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…
