Summary:
Rainier School District is a small Washington district serving about 1,017 students in three schools from prekindergarten through 12th grade: Rainier Elementary School, Rainier Middle School, and Rainier Senior High School. The district ranks in the 71st percentile statewide and has a four-star rating, but results vary considerably by grade level and subject.
Rainier Senior High School is the strongest overall school, ranking in the 76th percentile. It has especially good English language arts results, with 67.19% of students proficient, and science results of 63.75%. Its reported graduation rate is 95%. Math is the main weakness, however, with only 36.36% of students proficient. Rainier Elementary School, the largest school with 493 students, offers the most balanced performance: about half of students are proficient in English language arts and math, while 56.16% are proficient in science. Its math performance is the best in the district, although fifth-grade math falls to 39.73%, which may signal a need for additional support before middle school.
Rainier Middle School is the main area of concern for families. It ranks in the 44th percentile and has the lowest results in all three tested subjects: 45.13% proficiency in English language arts, 30.80% in math, and 43.75% in science. Math declined sharply from the prior year, with sixth-grade performance particularly low at 24.69%; eighth-grade math was also weak at 28.75%. The transition from fifth to sixth grade deserves close attention, including curriculum alignment and student intervention. The middle school also has the highest student-teacher ratio, 20.9, compared with 16.5 at the elementary school and 18.1 at the high school. Districtwide, science is the strongest subject relative to Washington, while math is the clearest priority for improvement.
