About Us

Our Graduation Success program pairs students in foster care with an in-school support person who can monitor their schooling, check in on behaviors, build goal-setting skills, and collaborate with their caregivers and social workers. Since its inception, Graduation Success has helped more than 1,900 young people complete high school. Students who participate in Treehouse’s Graduation Success program for at least two years are more likely to persist toward earning their high school diploma. For youth residing in areas Graduation Success cannot reach, Treehouse is leaning into systems improvement work to scale practices we know work.  

The Educational Advocacy program works with the adults supporting students in foster care to remove barriers to school success. This program serves the highest-need students, with the majority of cases requiring two to three interventions. In 2025, our Educational Advocacy program shifted to virtual support and opened their service area statewide. Between 2025 and 2026, Educational Advocacy saw a 10% increase in school districts represented in referrals. Caregivers, parents, social workers, and school personnel need assistance to keep the highest-needs students in school for a chance at graduation.  

Treehouse has operated as a direct service organization for nearly four decades, which means we’ve learned a lot about the systems surrounding youth experiencing foster care. Instead of solving the same opportunity gaps each year, Treehouse is working to improve the systems themselves to fix those gaps for good.  

Washington has some of the strongest education laws on the books thanks to Treehouse’s leadership alongside fellow partners. But it often takes more than implementing new practices to make perfect. Our systems improvement and advocacy work carry lasting change into pockets of the state we cannot reach and beyond.
