By Methodology

Document Reviews

  • Reports written off of review of existing documents, such as funded grant applications or existing curricula.

Process and Implementation Evaluations

  • Process and Implementation Evaluations focus on program implementation and operation and can answer questions regarding program effort, identify processes or procedures used to carry out the functions of the program, and address program operation and performance.

Quasi Experimental Evaluations

  • Quasi Experimental Evaluations use comparison groups rather than randomly-assigned control groups as the baseline or counter factual against which to measure net program impacts. Sources for such comparison groups include eligible non-participants in the same community, individuals similar to the participants from an existing database that contains the outcome measures of interest, or individuals in a matched comparison site who would have been eligible for the program if it were in that site.

Random Assignment Evaluations

  • Random Assignment uses a lottery system to randomly assign participants to the experimental group (treatment group) or to the control group. Participants in the treatment group can participate in the program or activities being evaluated. Participants in the control group cannot. The lottery system ensures that participants have an equal chance of being in the treatment or the control group. Although random assignment is the best way to ensure comparable groups, it is not appropriate or possible in every situation, such as when it would be illegal or unethical to deny treatment to participants.

Statistical Studies

  • Statistical Studies use existing data to examine research questions or hypotheses and determine if outcomes were likely to have occurred by chance alone.

Survey Research

  • Survey Research is a method involving the use of questionnaires or statistical surveys to gather data about people and their opinions or behaviors.
