Supervisors hear data showing math proficiency gains after $8 million lesson‑study pilot

The San Francisco Board of Supervisors heard on Oct. 29 that a city‑funded math pilot in four elementary schools produced measurable early gains and tangible classroom changes. Supervisor Hillary Ronan, who called the hearing, said the pilot shows “magic” when properly funded and supported.

Mira Carberry, grant manager for the Whole School Lesson Study pilot, told the board that “the proportion of proficient students in math increased from 21 percent to 34 percent” after two years of implementation, and that the program produced notable improvements for Black and Latinx students. The presentation included school‑level details: Leonard R. Flynn Elementary reported a 13‑percentage‑point rise in math proficiency and a 16% drop in chronic absenteeism in 2023–24, while teachers and principals described new classroom routines that prioritize student‑led problem solving.

Presenters described the pilot’s core components: investment in math interventionists and math instructional coaches, monthly professional learning communities, and a teaching‑through‑problem‑solving pedagogy paired with lesson‑study professional development. “Lesson study shifts the professional learning culture by valuing teachers’ professional expertise,” said Matt Fitzsimmons, principal of Malcolm X Academy, explaining how teacher inquiry cycles were used to improve instruction.

Supervisors pressed presenters on scalability and costs. Carberry and district leaders said the pilot initially cost about $4,000,000 in the first year and similar dollars in the second year and that ongoing annual budgets average roughly $600,000–$800,000 per additional site depending on the configuration and supports required. Board members asked whether the Student Success Fund could provide stable multi‑year funding; presenters and director-level officials said that fund is a primary candidate and described it as structured for long‑term support.

The superintendent, Dr. Maria Hsu, praised the pilot’s results and emphasized the need to preserve program fidelity: “You can’t cut the budget of this program and expect the same results,” she said, urging careful planning for expansion rather than a rushed, diluted roll‑out. The hearing closed with board members urging a path to scale that preserves coaches, interventionists, and teacher stipends that districts said are essential to producing the reported gains.

Next steps: staff and district officials said they will provide more detailed per‑school cost breakdowns and readiness criteria for expansion, and the board signaled support for pursuing Student Success Fund resources to sustain and scale the model.
