Elementary Schools in Clarkston School District

The Clarkston School District has four K–6 elementary schools serving about 1,230 students in the Clarkston, Washington, area. School performance varies considerably across the district, with 2025–26 statewide rankings ranging from 467th for Heights Elementary to 927th for Grantham Elementary. All four schools improved their rankings compared with 2023–24, although their current achievement levels remain notably different.

Heights Elementary is the district’s strongest and most consistent performer. It is the only three-star school, ranks in the 59th statewide percentile, and leads the district in all-grade English Language Arts, Math, and Science. Its Math and ELA results are also slightly above state averages. Parkway Elementary stands out for Math, matching Heights at roughly 44% proficiency overall and posting the district’s strongest third-grade ELA and Math results. However, Parkway’s performance declines in the upper grades, especially sixth-grade Math and ELA. Highland Elementary ranks third but has improved substantially over time and shows relatively strong sixth-grade results, despite weaker lower-grade ELA performance.

Grantham Elementary has the lowest current proficiency results in all three subjects, particularly in upper-grade Math and schoolwide ELA, but it also improved its ranking from the prior year. Across the district, Science is the clearest shared concern: every school declined year over year, and all remain below the state average. Families comparing schools may also note the broad achievement gap between Heights and Grantham, while recognizing that test scores are only one part of a school’s overall picture. Key areas to watch include sustaining Heights’ performance, supporting Parkway’s transition into later grades, strengthening Highland’s younger grades, and improving upper-grade Math and ELA at Grantham.
