Tenure: Delaware
Retaining Effective Teachers Policy
Analysis of Delaware's policies
Link to evidence of effectiveness: Delaware requires that probationary teachers show two years of satisfactory student growth—evidenced by satisfactory ratings in the student improvement component of the teacher appraisal process—within a three-year period before they earn tenure.
Basis for tenure: Delaware's teacher evaluation ratings include objective measures of student growth; therefore, classroom effectiveness is considered when making tenure decisions.
Recommendations for Delaware
Ensure that evidence of effectiveness is the determinative factor in tenure decisions.
Although Delaware's teacher evaluation ratings include evidence of student growth, the state does not make it a determinative factor in its teacher evaluations. Delaware should strengthen its policy and make evidence of effectiveness the most significant factor when determining this leap in professional standing.
State response to our analysis

How we graded
9B: Tenure
- Evidence of Effectiveness: The state should require:
- That tenure decisions be based on a process that evaluates cumulative evidence of classroom effectiveness.
- That evidence of effectiveness be the determinative factor in tenure decisions.
The total goal score is earned based on the following:
- Full credit: The state will earn full credit if it bases tenure requirements on a process that evaluates cumulative evidence of effectiveness, and if the evaluation system requires that teachers cannot be rated as overall effective if they receive an ineffective student growth rating.
- Three-quarters credit: The state will earn three-quarters of a point if it bases tenure requirements on a process that evaluates cumulative evidence of effectiveness, and if its evaluation system requires between 33 and 50 percent of a teacher's effectiveness rating to be based on student growth.
- One-half credit: The state will earn one-half of a point if it bases tenure requirements on a process that evaluates cumulative evidence of effectiveness, and if the evaluation system requires less than 33 percent of a teacher's effectiveness rating to be based on student growth.
- One-quarter credit: The state will earn one-quarter of a point if an evaluation process exists for granting teachers tenure, but the process does not require evidence of student growth.
Research rationale
Tenure should be a significant and consequential milestone in a teacher's career. The decision to give teachers tenure (or permanent status) is usually made automatically, with little thought, deliberation or consideration of actual performance.[1] State policy should reflect the fact that initial certification is temporary and probationary, and that tenure is intended to be a significant reward for teachers who have consistently shown effectiveness and commitment.[2] Tenure and advanced certification are not rights implied by the conferring of an initial teaching certificate. No other profession, including higher education, offers practitioners tenure after only a few years of working in the field.[3]
States should also ensure that evidence of effectiveness is the preponderant (but not the only) criterion for making tenure decisions.[4] Most states confer tenure at a point that is too early for the collection of sufficient and adequate data that reflect teacher performance. Ideally, states would accumulate such data for four to five years. This robust data set would prevent effective teachers from being unfairly denied tenure based on too little data and ineffective teachers from being granted tenure.

By routinely denying tenure to the bottom 25 percent of eligible teachers, the impact on student achievement would be equivalent to reducing class size across-the-board by 5 students a class.
