Summary

Twindly Bridge Charter School is a K-12 alternative charter school in Wasilla, AK, serving 601 students as part of the Matanuska-Susitna Borough School District, a district rated 4 stars and ranked 6th statewide. Twindly Bridge operates much more like an independent-study or correspondence program than a traditional classroom, with a student-teacher ratio near 110 to 1 — similar to Mat-Su Central School (99.2) but far higher than more conventional nearby options like Valley Pathways (14.3) or American Charter Academy (15.9). It is also a very low-cost model at about $8,669 per student, well below American Charter Academy’s $18,018 or Mat-Su Day School’s $54,341.

Academically, Twindly Bridge’s standout subject is science, with 85.7% of students scoring proficient versus 51.0% for the district and 37.8% for the state. That strength has held for several years and also beats nearby Knik Charter School (62.2%) and Mat-Su Central School (55.1%). English Language Arts is also above district averages at 52.4% proficient, compared with 41.5% for the district. Math is the relative weak spot, at 40.9% proficient — slightly below the district’s 42.0% but above the state’s 32.2%. Looking at grade levels, younger students tend to lag district peers in 3rd-grade ELA and math, while older students do very well: 8th-grade ELA proficiency was 71.4% versus the district’s 37.1%.

The school reports a very low free/reduced-price lunch population, suggesting its families may have more resources to support home-based learning than families at some neighboring alternative schools. The biggest caution flag is graduation rate volatility: after hitting 95.0% in 2023–2024, it dropped to 52.1% in 2024–2025, far below the district’s 84.2%. If that rate rebounds, Twindly Bridge looks like a strong and cost-efficient alternative school; if it persists, it could undermine confidence in the school’s otherwise impressive test scores.
