Summary:

ZIP code 99336 has two middle schools serving grades 6–8: Highlands Middle School and Park Middle School, both part of the Kennewick School District in the Kennewick area. The schools are similar in size, with Highlands enrolling 745 students and Park enrolling 688, and they have nearly identical student–teacher ratios of about 17.5 students per teacher. Both schools serve students with substantial academic needs and report proficiency levels below district and Washington averages, making continued academic improvement an important priority.

Park Middle School is the stronger overall performer in the latest results. Its 2025–26 proficiency rates are 41.47% in English language arts, 25.34% in math, and 26.20% in science, compared with 30.76%, 22.13%, and 30.40% at Highlands Middle School. Park also has the higher statewide ranking, placing in the 28th percentile compared with Highlands in the 16th percentile. Park’s biggest advantage is in English language arts, where it leads Highlands in every grade and reaches 46.32% proficiency in eighth grade. It also performs particularly well in sixth-grade math, at 34.10%. However, Highlands leads in science and is nearly equal to Park in eighth-grade math.

Both schools improved in every tested subject from the previous year, with the largest gains occurring in science. Highlands increased its science proficiency by 8.12 percentage points, while Park improved by 9.61 points. Highlands also reports higher spending per student—$17,772 versus $15,799 at Park—but Park currently has stronger overall results, showing that spending alone does not explain school performance. Seventh-grade math is a shared weakness, with proficiency near 20% at both schools. For parents comparing the two, Park offers the stronger current academic and ranking profile, while Highlands stands out for recent improvement and stronger science results. Families should also consider school programs, student support services, attendance, school climate, and transportation when making a choice.
