The bill S. 429 aims to amend the South Carolina Code of Laws by adding Article 5 to Chapter 10, Title 59, which authorizes evaluators to assess public school students for health, behavioral health, or therapeutic needs. It allows private providers to deliver related services during the school day, contingent upon requests from the student's parent or guardian. The bill stipulates that school districts cannot prohibit these evaluations or services and mandates the State Department of Education to adopt a model policy outlining the requirements for such evaluations and services.

Additionally, the bill defines key terms such as "evaluation," "private provider," and "evaluator," and establishes guidelines for the provision of medically necessary services. It requires school districts to adopt policies that comply with federal laws, including the Individuals with Disabilities Education Act and the Americans with Disabilities Act. The model policy must be finalized by November 1, 2025, and districts are required to adopt it or create their own compliant policies by January 1, 2026.
