Original Research by School Decision on Pinnacles Prep Charter School
Pinnacles Prep Charter School is a single-school public charter district in Chelan County, Washington. It opened in the fall of 2021 as the only tuition-free public charter middle and high school option in the Wenatchee Valley, a publicly reported fact that gives families an alternative to the traditional district school model. The school started with sixth grade and is progressively adding a grade each year, serving sixth through tenth grade in the 2024-25 school year and planning to reach sixth through twelfth grade by 2026-27. For the most recent year of data, the school served grades six through nine.
The student body is small. Most students are white, with a substantial share identifying as Hispanic. Data on the share of students who qualify for free or reduced-price meals, receive special education services, or are classified as English learners was not reported, so a parent may want to ask the school directly about these support populations.
The school participates in Washington’s state assessments. In math, the share of students scoring proficient or above varied by grade, with seventh grade showing a higher rate than sixth and eighth grade. In English language arts, the rates were somewhat higher than in math, with seventh and eighth grade again above sixth grade. In eighth-grade science, about one in three students met the proficiency bar. The overall proficiency index, which averages rates across all tested subjects and grades, placed Pinnacles Prep in the bottom quartile among Chelan County’s districts. The school is still young, and these results reflect its first years of operation. A parent may want to look into how the school is using these results to shape instruction and whether it expects proficiency to rise as the school matures.
Chronic absenteeism, which measures students who miss a significant portion of the school year, was reported at a rate that falls below the midpoint among the county’s districts, meaning it is higher than most of its peers. That is a soft spot worth noting, and a family may want to ask about the school’s attendance and engagement strategies.
Per-pupil current spending is in the middle range, lower half of the county’s districts. The school’s governance is that of a charter, which typically means it operates with some autonomy from the local school district in exchange for accountability on performance goals.
Because the school does not yet serve a full high school cohort, no graduation rate is available. The school’s plan to eventually offer grades six through twelve means that families who enroll now can stay through high school without needing to transition to a different school. That continuous pathway may appeal to families looking for a single school through the secondary years.
The district brief notes that the school’s grade span is expanding each year, so the current ninth grade will be the first class to potentially graduate from the school. This growth context matters: the school is still building its upper grades, its course offerings, and its track record. What is available now may not fully represent what will be in place when today’s sixth graders reach high school.
Overall, Pinnacles Prep offers a small, charter-governed option in the Wenatchee Valley with a grade span that is still expanding. Its academic results on state tests are on the lower side relative to other Chelan County districts, and its chronic absenteeism rate is higher than many of its neighbors. A family considering this school may want to learn more about the school’s academic approach, its student support systems, and its plans for the upper grades. The school is in an early phase of development, and its trajectory will be worth watching.
