Delivering Well Prepared Teachers Policy
The state should require teacher preparation programs to admit only candidates with strong academic records.
Iowa requires that approved undergraduate teacher preparation programs only accept teacher candidates who have passed a basic skills test. The test is normed just to the prospective teacher population. 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. 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 its current basic skills test requirement for candidates whose SAT or ACT scores demonstrate that they are in the top half of their class.
Consider requiring candidates to pass subject-matter tests as a condition of admission into teacher programs. In addition to ensuring that programs require a measure of academic performance for admission, Iowa might also want to consider requiring content testing prior to program admission as opposed to at the point of program completion. Program candidates are likely to have completed coursework that covers related test content in the prerequisite classes required for program admission. Thus, it would be sensible to have candidates take content tests while this knowledge is fresh rather than wait two years to fulfill the requirement, and candidates lacking sufficient expertise would be able to remedy deficits prior to entering formal preparation.
Iowa was helpful in providing facts that enhanced this analysis.
Preparation programs should screen candidates for academic proficiency.
Evidence is strong that countries whose students consistently outperform U.S. students set a much higher bar for teacher preparation programs than what is typically found in the United States. Research is also clear about the positive effects on student achievement of teachers with stronger academic backgrounds.
Far from the top third or even top tenth to which more selective countries limit candidates, most states do not even aim for the top 50 percent. Many states do not evaluate candidates' academic proficiency as a condition of admission to teacher preparation at all; most others set a low bar. Some of the states in this latter group require only a basic skills test. These tests generally assess middle school-level skills, and do not ensure that candidates are prepared to do college-level work. Others have a minimum GPA requirement, but only a handful demand at least a 3.0.
Screening candidates at program entry protects the public's investment.
Teacher preparation programs that do not screen candidates, particularly programs at public institutions that are heavily subsidized by the state, invest considerable taxpayer dollars in the preparation of individuals who may not be able to successfully complete the program and pass the licensing tests required to become a teacher. Candidates needing additional support should complete remediation prior to program entry, avoiding the possibility of an unsuccessful investment of significant public tax dollars.
Tests normed to the general college-bound population would improve selectivity.
In addition to the fact that current basic skills tests generally measure only middle school-level skills, another concern is that they are normed only to the prospective teacher population. Tests normed to the general college-bound population would shine a clearer light on the academic proficiency of those admitted to teacher preparation programs and allow programs to be truly selective.
