1. EVALUATION THEORY AND MODEL
Theory and model should have symbiotic relationship with practice
Theory connotes a body of knowledge that organizes, categorizes, describes, predicts, explains, and otherwise aids in understanding and controlling a topic
Model is an extension of theory which includes the "how to" components

2. There are more then fifty recognized program evaluation models are found in the literature
House (1978):System analysis, behavioral objectives, decision-making, goal-free, art criticism, accreditation, adversary, and transaction.
Guba and Lincoln (1989). 4 generations characterized by different methodologies: (a) measurement oriented, (b) description oriented, (c) judgment oriented, and (d) negotiation oriented,

3. Stufflebeam and Shinkfield (1985) classified evaluation models into three broad types
Pseudo-evaluation
Quasi-evaluation
True evaluation

4. In sum, Stufflebeam and Shinkfield (1985) and Guba and Lincoln (1989) advocate the use of formal, systematic, and comprehensive approaches of program evaluation.

5. Evaluation Standards
The Joint Committee on Standards for Educational Evaluation (1981) developed four categories of standards
utility standards
feasibility standards
propriety standards
accuracy standards.

6. Utility Standards
to ensure that an evaluation will serve the practical information needs of given audiences
the standards include audience identification, evaluator credibility, information scope and selection, valuational interpretation, report clarity, report dissemination, report timeliness, and evaluation impact.

7. Feasibility Standards
to ensure that an evaluation will be realistic, prudent, diplomatic, and frugal
Considerations involved are practical procedures, political viability, and cost effectiveness.

8. Propriety Standards
to ensure that an evaluation will be conducted legally, ethically, and with due regard for the welfare of those involved in the evaluation, as well as those affected by its results
these standards are formal obligation, conflict of interest, full and frank disclosure, the public's right to know, rights of human subjects, human interactions, balanced reporting, and fiscal responsibility.

9. Accuracy Standards
to ensure that an evaluation will reveal and convey technically adequate information about the features of the object being studied that determine its worth or merit
these standards are object identification, context analysis, described purposes and procedures, defensible information sources, valid measurement, reliable measurement, systematic data control, analysis of quantitative information, analysis of qualitative information, justified conclusions, and objective reporting.
