Teacher Licensure Tests and Student Achievement

Secondly, what are the technical characteristics of the three teacher tests used in California? These will be examined using existing technical reports and test score data from criteria put forth by the National Research Council. To examine whether multiple forms of evidence converge in identifying the same individuals as high or low in areas of teaching expertise, available validity evidence is being obtained, as well as information on correlations among scores on the three tests and between test scores and grade point averages in teacher education programs. To assess whether test scores differ systematically for different subgroups of teacher candidates, initial and eventual passing rates are being examined by race/ethnic group and by program type (i.e., traditional teaching programs versus alternative certification programs).

Finally, are scores on licensure tests a valid measure of teacher effectiveness? Value-added modeling is being used to examine whether these scores and other teacher characteristics are associated with gains in student performance on achievement tests, independent of background characteristics of students assigned to particular teachers.

The researchers will collect 3 years of student data for the first 2 cohorts of teachers included in this study and 2 years for the final cohort. Analyses will be conducted separately for multiple- and single-subject credential holders. This will allow a comparison of student achievement gains for teachers with single-subject credentials who demonstrate subject knowledge by passing required single-subject proficiency tests versus teachers who are allowed to waive testing and to demonstrate proficiency through completion of approved undergraduate coursework. The study will also address the question of whether middle school teachers with more subject-matter expertise produce greater pupil learning gains than those with multiple-subject credentials (more typical of elementary-level teachers).
