IPA assembled this set of resources for use in designing and running an impact evaluation. Beginning with the need for a theory-driven evaluation, and ending with a set of concrete tools to use in running an evaluation, they cover a range of practical materials useful for organizations that are considering a rigorous impact evaluation.

This set of resources cover the following topics:

• theories of change and impact evaluations
• determining the right timing for an evaluation
• selecting the right evaluation methodology
• designing and managing a randomized evaluation
• calculating sample size and doing power calculations
• mobile data collection
• administrative data
• data management and analysis

For organizations with strong internal technical capacity, these resources will provide valuable practical guidance for designing and implementing a credible impact evaluation. And for organizations without the internal capacity to design and run an impact evaluation, these resources will help key staff members understand the intricacies of a credible evaluation so they can recruit qualified external researchers to carry it out.
