program accomplishments, particularly progress towards pre-established goals.” Evaluations,
on the other hand, are “individual systematic studies conducted periodically or on an ad hoc
basis to assess how well a program is working.” While performance measures track whether a
program has met its objectives, goals, or targets, program evaluations analyze a wider range
of information, including important contextual information on the program, beneficiaries, and
the external environment, than is feasible to track on an ongoing basis.
Performance measurement and evaluation both include systematic data collection, and
performance measurement data may be included in analysis conducted for an evaluation. For
example: a reading tutoring program identifies the need and a theory of change for
addressing that need, e.g., students are reading below grade level and the tutoring program
can help them achieve reading success. The program develops performance measures and
identifies a primary outcome to measure their ability to address the need, e.g., the primary
outcome is to have students reading at or above grade level by the end of one year. The
program tests students’ reading ability as part of their performance measurement activities
and gathers evidence of the extent to which the students who participate in the tutoring
program improve their reading ability and are reading at grade level after one year. The
program then designs an evaluation that will allow them to compare the outcomes for the
students who participate in the tutoring program with a matched group of students that does
not receive the tutoring services. By comparing the outcomes for the two groups, the
evaluation can determine whether the students’ improved reading skills can actually be
attributed to the tutoring program and not to other factors, such as regular reading
improvement or classroom instruction. The greater the capacity of the evaluation to control
for the differences between the students who receive tutoring and the comparison group and
their experiences (outside of participation in the tutoring program), the stronger the case can
be made that the improvement in tutored students’ reading ability, when compared to the
other group, was the direct result of the tutoring program.
Additional information on how evaluation differs from performance measurement can be
found in the AmeriCorps regulations 45 CFR § 2522.700

30) Is it required that evaluations measure the impact of the primary
service activity on the service beneficiaries or the community? May
evaluations measure the impact of the program on AmeriCorps member
development?
Evaluations must measure the impact of one or more significant program activities, but not
necessarily the primary service activity. AmeriCorps encourages grantees to conduct
evaluations that will provide rigorous evidence of beneficiary impact and demonstrate that
the program is an effective means to solve community problems. However, AmeriCorps also
recognizes that the impact of program participation on AmeriCorps members may represent
a significant component of a grantee’s theory of change. For this reason, an evaluation
focused on member outcomes is allowable.
If you are interested in evaluating members, please be sure to include member activities and
outcomes in your theory of change and logic model.
