A review of HRD articles in a select set of journals indicated that some researchers reporting on pretest-posttest designs with two groups were not reporting associated statistical assumptions and reported results from repeated-measures analysis of variance that are considered of minimal utility. An alternative method of analysis for randomized pretest-posttest experiments is proposed. It yields treatment contrasts identical to those from ordinary analysis of covariance and also provides adjusted gain scores for each treatment group.
