Task 4: Select Evaluator


Guideline: Project size, evaluation purpose, and available resources impact whether internal staff members have the means to conduct the program evaluation or whether engaging an external evaluator is warranted. When selecting an evaluator give thought to the advantages/disadvantages of internal versus external evaluators. With an external evaluator it is important to know their experience as well as the cost of their services.

Prior to proceeding with the evaluation the organization should determine which approach seems most suited for its needs and the resources.
