Scale-Up in Education, Volume 2: Issues in Practice explores the challenges of implementing and assessing educational interventions in varied classroom contexts. Included are reflections on the challenges of designing studies for improving the instructional core of schools, guidelines for establishing evidence of interventions' impacts across a wide range of settings, and an assessment of national efforts to bring reform to scale in high-poverty schools.

Scale-Up in Education, Volume 1: Ideas in Principle examines the challenges of _scaling up_ from a multidisciplinary perspective. It brings together contributions from disciplines that routinely take promising innovations to scale, including medicine, business, engineering, computing, and education. Together the contributors explore appropriate methods for estimating the effects of innovations in larger, more diverse settings and provide theories and models to guide the design of innovations most likely to remain viable at large scales.
