Original Research by School Decision on Twindly Bridge Charter School
Twindly Bridge Charter School is a kindergarten-through-twelfth-grade charter school in Wasilla, Alaska, operating within the Matanuska-Susitna Borough School District. It sits in a community that blends commuter-suburb character with a regional commercial role. Wasilla stretches along the George Parks Highway, and a substantial share of its residents commute to Anchorage for work. The town is car-dependent and low-density, organized around the highway corridor rather than a walkable downtown grid. It has been growing rapidly, with residential development continuing to serve its bedroom-community function for Anchorage and the broader Mat-Su Valley.
The school enrolls a moderate number of students across all grade levels, but the population is concentrated in the elementary and middle grades. The high school grades thin out considerably, with far fewer students in grades nine through twelve than in the earlier years. This shape suggests that many families use Twindly Bridge for the younger grades and then transition students to other schools for high school, though the data does not tell us why. The student body is predominantly white, with a smaller multiracial segment and a modest Hispanic presence. A small number of Alaska Native students are enrolled as well.
On state assessments, the picture is mixed. In English language arts, proficiency is moderate, with nearly half of tested students meeting the proficient-or-above benchmark on the AK STAR assessment. Math proficiency is lower, with roughly a third of tested students reaching proficiency. Science stands out as a clear strength, with a large majority of the small number of tested students scoring proficient or above. The science result is encouraging, though it draws on a very small testing pool, which makes it less stable as a general indicator.
One issue a parent may want to look into further is participation. The reported participation rates on the state assessments are low across all three subjects. Low participation can mean the proficiency figures represent only a subset of eligible students, which complicates the read on overall academic performance. The school may have details about why participation was limited, and a parent asking that question directly would get a clearer picture.
The school does not have free-or-reduced-price lunch data, IEP rates, or English-learner rates in the available data. Without these, it is hard to characterize the level of economic need among students or the scope of special-population services. The data also does not include graduation rate information, course access details, staffing metrics, discipline data, or attendance figures. Program offerings such as AP, dual-credit, or career-pathway options were not available. We looked for the district's recent parent-relevant changes, such as curriculum shifts or facility investments, and found none reported.
The housing market in the school's zip code sits above both state and national benchmarks for typical home values, and values have been climbing at a healthy year-over-year pace. Rents are also rising modestly. The estimated monthly mortgage payment on a typical home exceeds the typical rent by a meaningful margin, and rent absorbs roughly a quarter of median household income. For families considering a move into the area, housing costs are a factor, though the price-to-income ratio remains below the level seen in many higher-cost markets.
What Twindly Bridge offers is a charter option spanning the full K-12 range in a rapidly growing commuter community. Its science results are a bright spot, English is reasonable, and math is an area where a parent may want more detail. The thin high school enrollment and low assessment participation are the two questions most worth raising with the school before making a decision. The surrounding community is auto-oriented and expanding, with housing costs on the higher side for the region but still within reach for many working families.
