Summary:
The Moses Lake School District has three middle schools serving grades 6–8: Columbia Middle School, Frontier Middle School, and Endeavor Middle School. Together, they enroll about 1,835 students in the Moses Lake area. Columbia is the largest school with 875 students, followed by Frontier with 690 and Endeavor with 270. All three schools are below Washington’s average proficiency levels in English, math, and science, although their results and recent trends differ considerably.
Columbia Middle School is the district’s strongest academic performer. In 2025–26, about 41% of students were proficient in English, 34% in math, and 36% in science, leading the district in all three subjects. Its strongest grade-level result was 7th-grade math, at 42%. Frontier Middle School ranked behind Columbia but showed encouraging progress, improving from the 17th to the 26th state percentile over three years. Its science proficiency rose nearly 9 percentage points in one year, and its 8th-grade math performance was a relative strength. Frontier also reports the lowest student–teacher ratio of the three schools.
Endeavor Middle School has the lowest current achievement levels, with proficiency of about 24% in English, 20% in math, and 22% in science. However, it has made notable gains in English and math and improved from the 1st to the 10th state percentile over three years. Its 8th-grade results, especially math at 8%, deserve close attention because they are much lower than its 7th-grade results. Endeavor also serves a higher-need student population and has the highest reported spending per student, so comparisons should consider student needs, attendance, mobility, and cohort size. Parents may view Columbia as the district benchmark, Frontier as a school gaining momentum, and Endeavor as a school showing improvement but requiring substantial continued support.
