Analysis of Missouri's policies

Missouri does not connect tenure decisions to evidence of teacher effectiveness.

Teachers in Missouri are awarded tenure automatically after a five-year probationary period, absent an additional process that evaluates cumulative evidence of teacher effectiveness.

Recommendations for Missouri

End the automatic awarding of tenure.
The decision to grant tenure should be a deliberate one, based on consideration of a teacher's commitment and actual evidence of classroom effectiveness. 

Ensure evidence of effectiveness is the preponderant criterion in tenure decisions.
Missouri should make evidence of effectiveness, rather than the number of years in the classroom, the most significant factor when determining this leap in professional standing.

Articulate a process that local districts must administer when deciding which teachers get tenure.
Missouri should require a clear process, such as a hearing, to ensure that the local district reviews a teacher's performance before making a determination regarding tenure. 

State response to our analysis

Missouri recognized the factual accuracy of this analysis.

Research rationale

Numerous studies illustrate how difficult and uncommon the process is of dismissing tenured teachers for poor performance. These studies underscore the need for an extended probationary period that would allow teachers to demonstrate their capability to promote student performance.

For evidence on the potential of eliminating automatic tenure, articulating a process for granting tenure, and using evidence of effectiveness as criteria for tenure see D. Goldhaber and M. Hansen, "Assuming the Potential of Using Value-Added Estimates of Teacher Job Performance for Making Tenure Decisions." Center for Reinventing Public Education. (2009).  Goldhaber and Hansen conclude that if districts ensured that the bottom performing 25 percent of all teachers up for tenure each year did not earn it, approximately 13 percent more than current levels, student achievement could be significantly improved. 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.
