The Individualized Family Service Plan (IFSP) is a mechanism designed to identify and meet the unique needs of very young children with disabilities, ages birth through two years of age, and their families. Under Part C of the U.S. Individuals with Disabilities Education Act (IDEA, 2004), the IFSP is written by a team, made up of early intervention professionals and the family, and specifically addresses the priorities and concerns of the family as it relates to the development of their infant or toddler. Specific components of the IFSP are required and include the present levels of development for the young child, the priorities and concerns of the family, outcomes for the child and family, measures for success in meeting those outcomes, and transition plans as the child approaches the age of three years. As the nature of early intervention is family-centred, the family is considered to be a valuable, contributing member of the team, and the written contents of the IFSP should not only reflect this principle, but also guide service delivery.
