Equity Requirements in IDEA

The Individuals with Disabilities Education Act (IDEA) has three distinct requirements around equity: Disproportionate Representation (State Performance Plan/Annual Performance Report [SPP/APR] Indicators B9 and B10), Significant Discrepancy (SPP/APR Indicators B4A and B4B), and Significant Disproportionality. This resource can help clarify the differences and similarities among the three equity requirements and enable users to compare and contrast these various equity requirements.
