Summary:

Zip code 99115 contains one high school, Almira Coulee Hartline High School, a small rural school in Coulee City, Washington, serving grades 9-12 with just over 100 students.

This school stands out for its consistent high performance, ranking in the top 15% of all Washington high schools for three consecutive years. It excels particularly in English Language Arts and Science, where student proficiency rates are significantly higher than the state averages. The school is part of the Coulee-Hartline School District, and its academic results closely align with strong district-wide performance.

With a low student-teacher ratio, the school offers a personalized learning environment that appears effective, as it achieves these strong academic outcomes while serving a student population where a notable portion are economically disadvantaged. While mathematics proficiency is closer to the state average, the school's 10th graders perform particularly well in both math and English compared to their peers statewide. The school's sustained excellence over multiple years makes it a reliably high-quality educational option in this area.
