This booklet provides information about the state of Mississippi's Prepaid Affordable College Tuition Program. The state-guaranteed program creates tax-exempt monthly or lump-sum prepayment plans that cover tuition and all mandatory fees at state-supported colleges or universities, are portable to private and out-of-state schools, and can be transferred to other children in a family. The booklet sets forth eligibility requirements; explains the three types of plan available--junior or community college, senior college, or junior/senior college; defines refund policies; and includes charts that calculate costs for each type of plan. Also listed are the four-year and two-year public and private institutions in the state covered under the program. (CH)
