How does evaluation differ from performance measurement?

§ 2522.700 How does evaluation differ from performance measurement?

(a) Evaluation is a more in-depth, rigorous effort to measure the impact of programs. While performance measurement and evaluation both include systematic data collection and measurement of progress, evaluation uses scientifically-based research methods to assess the effectiveness of programs by comparing the observed program outcomes with what would have happened in the absence of the program. Unlike performance measures, evaluations estimate the impacts of programs by comparing the outcomes for individuals receiving a service or participating in a program to the outcomes for similar individuals not receiving a service or not participating in a program. For example, an evaluation of a literacy program may compare the reading ability of students in a program over time to a similar group of students not participating in a program.
