Using Available Evidence to Estimate the Cost of Educational Adequacy

Abstract

This article seeks to move the adequacy issue forward by demonstrating that under a certain set of assumptions, it is possible to provide a set of programmatic offerings that corresponds well with what we consider to be an emerging, research-based consensus about what constitutes best practices. We do this by showing what could be purchased with the national average expenditure per pupil if it were to be applied to one adequacy approach, the evidence-based approach, and how these resources have been linked to increases in student performance.
