Children in the two experimental groups will be administered a neurodevelopmental evaluation, and, in addition, will receive academic follow-up on either a quarterly or annual basis, depending upon to which group they are randomized. Enrollment is on an ongoing basis and each participant will be followed for 3 years after enrollment, receiving a neurodevelopmental evaluation each year with a final endpoint evaluation at year 4 (a total of 4 neurodevelopmental evaluations).
