The question on the Nov. 4 ballot would amend the Missouri Constitution to limit teacher tenure and tie student performance data to educator evaluations.

Campaign finance reports filed Wednesday show the Committee in Support of Public Education received more than $1.7 million in the latest quarter to fight the measure and spent about $50,000 on advertising. The group has about $1.4 million.

The initiative’s sponsor, Teach Great, no longer is campaigning because of poor public polling results.

Teach Great was financed by investment firm founder Rex Sinquefield and did not receive any donations in the latest quarter.
