Disproportionality is a term used in special education to describe a situation where there are significant disparities in the identification, placement, or discipline of students with disabilities in comparison to their non-disabled peers, within a particular LEA. The Individuals with Disabilities Education Act (IDEA) requires states to identify significant disproportionality in its LEAs and take action to address it. In California, this work is supported by the State Performance Plan Technical Assistance Project (SPP-TAP), through a 4-phase process, by applying a cultural lens to local policy and practice.
