Effective Interventions Unit : evaluation guide 2 : planning an evaluation

This is the second evaluation guide in the Effective Interventions Unit Evaluation series. This guide aims to explain the planning stage of an evaluation by describing the steps necessary in planning both an intervention and an associated evaluation, identifying some general questions to address when planning an intervention, and outlining some questions that evaluations commonly tackle.

To help illustrate the main points in this guide, an example of a fictitious outreach needle exchange service is used.
