The psychometric properties of the testing tools of the Michigan Educational Assessment Program (MEAP), the state standardized testing program, are examined. Reliability studies have indicated that the scores from the MEAP, ranging from 0.654 to 0.949, are generally acceptable. The State Department of Education offered supporting evidence for the tests' criterion and construct validity and further concluded that no criterion evidence could be offered, since no other test matched the purpose of the MEAP. An independent evaluation by the Saginaw public schools (Michigan) suggested a generally low criterion validity for the story selection test and poor validity for Hispanic students. The remaining tests fell below an acceptable level for criterion validity. Another factor in considering the validity of the MEAP is the high stakes nature of the testing program, with its consequences for school districts. This may lower the validity of scores. Another factor is the exclusion of special education students. Overall, the MEAP has some advantages, but its tests have not demonstrated adequate reliability or validity to make decisions about individual students, asses writing skills adequately, assess Hispanic students, or make decisions about district or teacher effectiveness. Some alternatives to the MEAP's use are offered. (Contains 3 tables and 26 references.) (SLD)
