Koretz, D., Stecher, B., Klein, S., & McCaffrey, D. (1994). The Vermont portfolio assessment program: Findings and implications. Educational Measurement: Issues and Practice, 13(3), 5-16.
Koretz and colleagues report on effects of the Vermont Portfolio Assessment Program. The authors begin by describing the program and then explain program implementation and findings from principal and teacher interviews. Koretz and colleagues also discuss the quality of achievement data, focusing on inter-rater reliability and the quality of aggregate data. The authors conclude by discussing implications for performance-assessment programs which includes having realistic expectations for program effects, understanding the large costs of implementation, and carefully monitoring after program implementation.
