Program & Program Evaluation

Program:

A program is a set of resources and activities directed toward one or more common goals, typically under the direction of a single manager or management team.

Program Evaluation:

Program evaluation is the application of systematic methods to address questions about program operations and results. It may include ongoing monitoring of a program as well as one-shot studies of program processes or program impact. The approaches used are based on social science research methodologies and professional standards.

Five questions to ask

• Can the results of the evaluation influence decisions about the program?
• Can the evaluation be done in time to be useful?
• Is the program significant enough to merit evaluation?
• Is program performance viewed as problematic?
• Where is the program in its development?

Type of evaluation

Formative ↔︎ Summative
Ongoing ↔︎ One-Shot
Objective ↔︎ Observers Participatory
Goal-Oriented ↔︎ “Goal-Free”
Quantitative ↔︎ Qualitative
Ex Ante ↔︎ Post Program
Problem Orientation ↔︎ Non-Problem

Types and uses of evaluation

Evaluation Types	When to use	What it shows	Why it is useful
Formative Evaluation Evaluability Assessment Needs Assessment	- During the development of a new program. - When an existing program being modified or is being used in a new setting or with a new population.	- Whether the proposed program elements are likely to be needed, understood, and accepted by the population you want to reach. - The extent to which an evaluation is possible, based on the goals and objectives.	- It allows for modification to be made to the plan before full implementation begins. - Maximizes the likelihood that the program will succeed
Process Evaluation Program Monitoring	- As soon as program implementation begins. - During operation of an existing program.	- How well the program is working - The extent to which the program is being implemented as designed - Whether the program is accessible and acceptable to its target population	- Provides an early warning for any problems that may occur - Allows programs to monitor how well their program plans and activities are working
Outcome Evaluation Objectives-Based Evaluation	- After the program has made contact with at least one person or group in the target population	- The degree to which the program is having an effect on the target population’s behaviors.	- Tells whether the program is being effective in meeting its objectives.
Economic Evaluation: Cost Analysis, Cost-Effectiveness Evaluation, Cost-Benefit Analysis, Cost-Utility Analysis	- At the beginning of a program - During the operation of an existing program.	- What resources are being used in a program and their costs (direct and indirect) compared to outcome	- Provides program managers and funders a way to assess cost relative to effects. “How much bang for your buck.
Impact Evaluation	- During the operation of an existing program at appropriate intervals. - At the end of a program.	- The degree to which the program meets its ultimate goal on an overall rate of STD transmission (how much has program X decreased the morbidity of an STD beyond the study population).	- Provides evidence for use in policy and funding decisions

Process evaluation can be very useful

Exploratory evaluation

Approach	Purpose	Time
Evaluability assessment	Assess whether programs are ready for useful evaluation; get agreement on program goals and evaluation criteria; clarify the focus and intended use of further evaluation.	1 to 6 months; 2 staff-weeks to 3 staff-months
Rapid feedback evaluation	Estimate program effectiveness in terms of agreed-on program goals; indicate the range of uncertainty in the estimates; produce tested designs for more definitive evaluation; clarify the focus and intended use of further evaluation.	3 to 6 months; 3 to 12 staff-months
Evaluation synthesis	Synthesize findings of prior research and evaluation studies.	1 to 4 months; 1 to 3 staff-months
Small-sample studies	Estimate program effectiveness in terms of agreed-on program goals; produce tested measures of program performance.	1 week to 6 months; 1 staff-week to 12 staff-month

Evaluability Standards: Readiness for Useful Evaluation

• Program goals are agreed on and realistic.
• Information needs are well defined.
• Evaluation data are obtainable.
• Intended users are willing and able to use evaluation information.

Selecting an exploratory evaluation approach

Approach	When Appropriate
Evaluability assessment	Large, decentralized program; unclear evaluation criteria.
Rapid feedback evaluation	Agreement exists on the goals in terms of which a program is to be evaluated; need for evaluation information “right quick”; potential need for more definitive evaluation.
Evaluation synthesis	Need for evaluation information “right quick”; potential need for more definitive evaluation.
Small-sample studies	Agreement exists on the goals in terms of which a program is to be evaluated; collection of evaluation data will require sampling.

Evaluation process and feedback

GAO’s Evaluation Design Process

• clarify the study objectives;
• obtain background information on the issue and design options;
• develop and test the proposed approach;
• reach agreement on the proposed approach.
