Delivering Well Prepared Teachers Policy
The state should require undergraduate teacher preparation programs to admit only candidates with good academic records.
Iowa requires that approved undergraduate teacher preparation programs only accept teacher candidates who have passed a basic skills test. Although the state sets the minimum score for this test, it is normed just to the prospective teacher population.
Also, Iowa does not allow teacher preparation programs to exempt candidates who demonstrate equivalent performance on a college entrance exam.
Iowa Code Title VII Chapter 256.16
Require preparation programs to use a common test normed to the general college-bound population.
The basic skills tests in use in most states largely assess middle school-level skills. To improve the selectivity of teacher candidates—a common characteristic in countries whose students consistently outperform ours in international comparisons—Iowa should require an assessment that demonstrates that candidates are academically competitive with all peers, regardless of their intended profession. Requiring a common test normed to the general college population would allow for the selection of applicants in the top half of their class, as well as facilitate program comparison. Iowa's policy is especially weak because the state allows individual teacher preparation programs to set their own passing scores.
Exempt candidates with comparable SAT or ACT scores.
Iowa should waive the basic skills test requirement for candidates whose SAT or ACT scores demonstrate that they are in the top half of their class.
Iowa was helpful in providing NCTQ with facts that enhanced this analysis.
