Licensure Advancement

2011 Identifying Effective Teachers Policy

2011 Goals for Licensure Advancement

The state should base licensure advancement on evidence of teacher effectiveness.

Best practices

Rhode Island is integrating certification, certification renewal and educator evaluation. Teachers who receive poor evaluations for five consecutive years are not eligible to renew their certification. In addition, teachers who consistently receive 'highly effective' ratings will be eligible for a special license designation.

How we graded

The reason for probationary licensure should be to determine teacher effectiveness.

Most states grant new teachers a probationary license that must later be converted to an advanced or professional license. A probationary period is sound policy as it provides an opportunity to determine whether individuals merit professional licensure. However, very few states require any determination of teacher performance or effectiveness in deciding whether a teacher will advance from the probationary license. Instead, states generally require probationary teachers to fulfill a set of requirements to receive advanced certification. Thus, ending the probationary period is based on whether a checklist has been completed rather than on teacher performance and effectiveness.

Most state requirements for achieving professional certification have not been shown to affect teacher effectiveness.

Unfortunately, not only do most states fail to connect advanced certification to actual evidence of teacher effectiveness, but also the requirements teachers must most often meet are not even related to teacher effectiveness. The most common requirement for professional licensure is completion of additional coursework, often resulting in a master's degree. Requiring teachers to obtain additional training in their teaching area would be meaningful; however, the requirements are usually vague, allowing the teacher to fulfill coursework requirements from long menus that include areas having no connection or use to the teacher in the classroom. The research evidence on requiring a master's degree is quite conclusive: These degrees have not been shown to make teachers more effective. This is likely due in no small part to the fact that teachers generally do not attain master's degrees in their subject areas. According to the National Center for Educational Statistics, less than one-fourth of secondary teachers' master's degrees are in their subject area, and only seven percent of elementary teachers' master's degrees are in an academic subject.

In addition to their dubious value, these requirements may also serve as a disincentive to teacher retention. Talented probationary teachers may be unwilling to invest time and resources in more education coursework. Further, they may well pursue advanced degrees that facilitate leaving teaching.

Research rationale

For a meta-analysis of the research on the relationship between advanced degrees and teacher effectiveness, see Metin and Stevenson, "The Impact of Teachers' Advanced Degrees on Student Learning" which has been published as an appendix in Arizona's Race to the Top: What Will It Take to Compete? (NCTQ, 2009).
