Peer reviewedBryk, Anthony S.; Weisberg, Herbert I. – Journal of Educational Statistics, 1976
Focuses on the fact that an educational treatment typically involves an intervention in a growth process. By modelling this process, expected growth for various treatment groups under control conditions may be estimated. Actual growth can be compared with projected growth to estimate the value-added by the program. A simple model is developed. (RC)
