IDEA is the primary source of funding for early intervention services for children with disabilities from birth to age 3.

The purpose of Part C of IDEA is to provide early intervention services to infants and toddlers with disabilities in order to help them develop and learn.

A child is eligible for early intervention services under Part C of IDEA if they have a disability that is expected to result in developmental delay, if they are experiencing developmental delay, or if they are at risk for developmental delay.

The IFSP is a written plan that identifies the child's needs and strengths, develops goals for the child, and determines the services that the child will receive.

The IFSP is developed by a team of professionals, including the early intervention service provider, the child's parents, and other professionals who work with the child.

The core early intervention services that must be provided under Part C of IDEA include physical therapy, occupational therapy, and speech-language therapy.

The state lead agency is responsible for administering the early intervention program, developing policies and procedures for the early intervention program, and monitoring the early intervention program.

The local lead agency is responsible for providing early intervention services to children and families, developing the IFSP, and coordinating services for children and families.

The service coordinator is responsible for helping families access early intervention services, coordinating services for children and families, and advocating for children and families.

The early intervention service provider is responsible for providing early intervention services to children, developing the IFSP, and working with families to implement the IFSP.

The family is responsible for being involved in the development of the IFSP, participating in early intervention services, and advocating for their child.

The community is responsible for providing support to families, providing resources to families, and advocating for children and families.

The state is responsible for administering the early intervention program, developing policies and procedures for the early intervention program, and monitoring the early intervention program.

The federal government is responsible for providing funding for the early intervention program, developing policies and procedures for the early intervention program, and monitoring the early intervention program.

The early intervention system faces a number of challenges, including a shortage of qualified personnel, a lack of funding, and a lack of coordination between agencies.
