The state should ensure that secondary teachers are sufficiently prepared to teach appropriate grade-level content.
Oklahoma requires that its secondary teacher candidates pass a content test to teach any core secondary subjects. Unfortunately, Oklahoma permits a significant loophole to this important policy by allowing both combination science and combination social studies licenses, without requiring subject-matter testing for each subject area within these disciplines (see Goals 1-G and 1-H).
Further, to add an additional field to a secondary license, teachers must also pass a content test. However, as stated above, Oklahoma cannot guarantee content knowledge in each specific subject for those secondary teachers who add combination science or combination social studies endorsements.

Require subject-matter testing for all secondary teacher candidates.
Oklahoma wisely requires subject-matter tests for most secondary teachers but should address any loopholes that undermine this policy (see Goals 1-G and 1-H). This applies to the addition of endorsements as well.
Oklahoma recognized the factual accuracy of this analysis.
Research studies have demonstrated the positive impact of teacher content knowledge on student achievement. For example, see D. Goldhaber, "Everyone's Doing It, But What Does Teacher Testing Tell Us About Teacher Effectiveness?" Journal of Human Resources, vol. XLII no.4 (2007). See also Harris, D., and Sass, T., "Teacher Training, Teacher Quality and Student Achievement." Teacher Quality Research (2007).Evidence can also be found in White, Pressely, DeAngelis "Leveling up: Narrowing the teacher academic capital gap in Illinois" Illinois Education Research Council (2008); D. Goldhaber and D. Brewer, "Does teacher certification matter? High School Certification Status and Student Achievement." Educational Evaluation and Policy Analysis. 22: 129-145. (2000); and D.
