Factors involved in pre-planned and post-planned evaluation of program effectiveness are compared: (1) reliability and cost of data; (2) internal and external validity; (3) obtrusiveness and threat; (4) goal displacement and program direction. A model to help program administrators decide which approach is more appropriate is presented. (Author/MH)
