Introduction

Purpose: To provide clear, practical advice on reporting the results of an evaluation of an educational program or practice ("intervention").

Specifically, this is a guide for researchers, and those who sponsor and use research, to reporting the results of "impact" studies — that is, studies which evaluate the effectiveness of an intervention by comparing participants’ educational outcomes (e.g., reading or math skills) with:

(i) those of a control or comparison group that does not receive the intervention, or

(ii) participants’ preintervention ratings on these outcome measures.

The Guide suggests key items to include in the study report so as to give the reader a clear understanding of what was evaluated, how it was evaluated, and what the evaluation found.¹
