Evaluation Theory and Models

System analysis approach
- quantitative output measures, usually test scores
- tries to relate differences in programs to variations in test scores - survey and experimental methodology

Behavioral objectives model
-objectives of a program are spelled out in terms of specific student performances or behaviors _uses test scores to measure the behaviors, using norm references or criterion references as standards

Accreditation evaluation model
-employs out¬side professionals to judge programs using a set of external standards -a coop¬erative effort
