The Student Aid Commission may determine that an advanced payment is essential to assure that funds provided pursuant to this chapter to assist students to enroll in postsecondary education are available at the time students enroll. Upon making that determination, the Student Aid Commission may, based on institutional academic calendars, advance per term to authorized postsecondary educational institutions the funds for eligible students who have indicated they will attend those institutions less an amount based on historical claim enrollment attrition information. Each institution shall disburse the funds in accordance with the provisions set forth in the Institutional Agreement between the Student Aid Commission and the institution.
