About schools in Grant County
Grant County's 49 ranked public schools span 10 districts across a wide stretch of central Washington, from Moses Lake to Quincy and the smaller communities of Mattawa and Ephrata. Statewide comparisons tell an honest story: only two schools land in the top quartile, with Sage Point Elementary in Moses Lake reaching the 78th percentile and Coulee City Elementary at the 75th. That's a modest showing for a county of this scale, though Columbia Middle School in Moses Lake holds its own at the 68th percentile. Families weighing this county should focus their search on those specific schools and districts rather than assuming consistent performance across the board.
