IFSP Implementation in the Fourth Year of P.L. 99--457

Abstract
After 4 years of planning under Part H, data reveal that the phase-in of the early intervention program is behind schedule. When we ask, How are IFSPs working? we find that IFSPs are not universally in place. However, many states have established pilot projects in which IFSPs are implemented. Further, 5 of the first 10 states to officially begin the fourth year of participation under Part H are able to assure the full implementation of IFSPs, in spite of the lack of a requirement to do so in the fourth year.
