Our ongoing research shows many districts funnel at least a portion of their dollars through an SBA formula to allocate money to schools. But even as the number of SBA districts grows, little research has documented the range of their SBA formulas, the extent to which they change how resources are used, the degree to which they are meeting their stated goals of improving equity, flexibility and transparency. Our federally funded three-year study into SBA will help fill the void. We also host a network of districts exploring or implementing student based allocation formulas. This collaborative network meets virtually once a month to explore current research, troubleshoot common challenges and support efforts to advance SBA formulas in local context.
