Investing in a prepaid tuition plan allows you to lock in current tuition rates for future education, protecting you against tuition inflation, while a college savings plan offers more flexibility in terms of where and how the funds can be used. Prepaid tuition plans are best for those who are certain their child will attend an in-state public college, whereas college savings plans are more suitable for those who prefer the flexibility to use the funds at any accredited institution, including private and out-of-state schools. Consider your family's needs and the likelihood of your child's educational path when making this decision.
