A new rating system for Missouri's school districts will intensify pressure on low-performing school districts to improve while exposing some of the best school districts to new scrutiny from parents and the public, the St. Louis Post-Disatch reports.

According to the report, the changes will roll out this summer and could mean more districts statewide won't meet minimum standards for state accreditation.

For districts like Pattonville and Parkway—two districts that claimed perfect scores in previous ratings—their scores could would even go down.

From the Post-Dispatch's:

For example, Mehlville, Parkway, Pattonville and Rockwood had perfect scores under the old rating, but under the new scale would score 97.9, 98.2, 87.5 and 96.8 percent, respectively, based on recent performance data.

“With that wider scale, it gives districts more information about where they need to improve, and also gives parents a better idea of how their schools are performing,” said Sarah Potter, spokeswoman for the Missouri Department of Elementary and Secondary Education. “That definitely is one of the goals.”
