Brilla runs the Brilla Solis Summer Boost Program to address summer learning loss, with plans for July 6–31, 2026 to serve 500 students after serving 320 the prior year. The program is staffed by stipend-supported teachers, is free for families, and has shown strong gains in ELA, but leaders acknowledged concern about reliance on annual grants and a desire for multi-year commitments. Funding is currently expected from a Bloomberg philanthropic grant, and separate minutes note approximately 450000 in Bloomberg support with a three-year commitment for related summer programming.This creates an ongoing need to manage grant-funded curriculum, enrichment services, assessments, and potentially to diversify funding and delivery partners. Vendors offering evidence-based summer curricula, data/reporting to satisfy philanthropic funders, and grant-aligned program design can help Brilla maximize this expansion and prepare for sustainability beyond the Bloomberg commitment.

Program targets summer learning loss in ELA and math, with strong prior outcomes (nearly half reaching basic or proficient ELA). Reliance on philanthropic funding is explicitly flagged as a risk.
