The city’s small, academically nonselective high schools have substantially improved graduation rates for disadvantaged students. This report demonstrates that, because more of their students graduate and do so within four years, the schools have lower costs per graduate than the schools their study counterparts attended.
Design Options for an Evaluation of Head Start Coaching
Using a study of coaching in Head Start as an example, this report reviews potential experimental design options that get inside the “black box” of social interventions by estimating the effects of individual components. It concludes that factorial designs are usually most appropriate.
This report provides recommendations for an evaluation of coaching that may impact teacher and classroom practices in Head Start and other early childhood settings — including about the research questions; the design of the impact study, implementation research, and cost analysis; and logistical challenges for carrying out the design.
