To find the most up-to-date information, you'd need to consult the Massachusetts Department of Elementary and Secondary Education (DESE) website. They publish detailed statistics on school enrollment and staffing, allowing you to calculate ratios at various levels of granularity. However, you won't find a single "total" number representing the entire state.
