In Fall 1994, the San Diego Community College District (SDCCD), in California, conducted a study to determine the validity of the Mathematics Diagnostic Testing Project (MDTP) placement test. The MDTP provides tests at four levels (i.e., algebra readiness, elementary algebra, intermediate algebra, and pre-calculus) and is used in the District for mathematics placement. The study sample consisted of 2,294 District students who took the test in fall 1994 and were subsequently placed in elementary algebra, intermediate algebra, or trigonometry courses. Test scores were compared to student ethnicity, gender, age, and achievement as measured by grades in the mathematics courses and student grade point averages (GPAs). Study findings included the following: (1) for elementary algebra students, the MDTP elementary algebra test was a better predictor of GPA than the algebra readiness test; (2) for intermediate students, the correlation between the intermediate test and GPA was stronger than the correlation found between the elementary test and GPA; (3) no correlation was found between intermediate algebra test scores and GPA for trigonometry students; and (4) while significant effects were found for student characteristics on MDTP test scores, these were reduced by factoring in students' number of years spent out of school before entering college and high school GPA. Appendixes comprising 90% of the publication provide data on cut score validity, test score validity, the relationship between test scores and assessment survey responses, the effect of student characteristics on test scores, and demographics survey from the MDTP.
