Is there any elementary or middle schools in Oklahoma with 2nd to 5th grades?

While the specific grade configurations vary widely among Oklahoma's elementary and middle schools, it's highly unusual to find a school with *only* grades 2nd through 5th. Most schools either encompass K-5 (or K-6), or have a clear distinction between elementary (K-5) and middle school (6-8).

You might find a school with a slightly unusual configuration due to things like small rural districts or specialized programs, but a school exclusively grades 2-5 would be the exception, not the rule. You'd need to search the Oklahoma State Department of Education website or contact individual school districts to verify their specific grade levels.
