The bill H. 5309 seeks to amend the South Carolina Code of Laws by introducing Chapter 64, which establishes the "Interstate Teacher Mobility Compact." This compact is designed to facilitate the movement of teachers across participating states by creating a streamlined licensure process, particularly for eligible military spouses, and improving the exchange of licensure and disciplinary information. It emphasizes state sovereignty in regulating the teaching profession while aiming to reduce barriers to the employment and retention of qualified teachers from other states. Key definitions related to the compact, such as "active military member" and "unencumbered license," are also provided.

Additionally, the bill outlines the governance structure of the Interstate Teacher Mobility Compact Commission, which will oversee the compact's implementation and compliance among member states. The commission will consist of delegates from each member state and will have the authority to create binding rules, manage finances, and ensure transparency. It also includes provisions for qualified immunity for commission members, emergency rule adoption, and mechanisms for addressing compliance issues among member states. The compact remains effective even if the number of member states falls below ten and allows for amendments and withdrawals under specified conditions, with a focus on the severability of its provisions.
