Cross-state metro note: The Lewiston, ID-WA metro spans ID and WA. Schools are ranked separately on each state's side — the states administer their tests independently, and no cross-state comparison is made. (Both states use Smarter Balanced for grades 3–8 ELA/math, but administrations and populations differ.)
