A Randomized Evaluation is a type of Impact Evaluation
that uses random assignment to allocate resources, run programs, or apply policies as part of the study design. Like all impact evaluations
, the main purpose of randomized evaluations is to determine whether a program has an impact, and more specifically, to quantify how large
that impact is. Impact evaluations measure program effectiveness typically by comparing outcomes of those (individuals, communities, schools, etc) who received the program against those who did not. There are many methods
of doing this. But randomized evaluations are generally considered the most rigorous and, all else equal, produce the most accurate (i.e. unbiased) results.
The methodology section covers the what
, and how
of randomized evaluations.
