Which of the following best describes the purpose of IDEA's Part C regulations?

The purpose of IDEA's Part C regulations is to mandate early intervention services for infants and toddlers with developmental delays. This provision recognizes the critical importance of addressing developmental needs as early as possible to enhance a child's growth and development. Early intervention aims to support children's physical, cognitive, communication, social-emotional, and adaptive development and can involve a variety of services provided in natural environments, such as their homes or community settings.

By emphasizing early intervention, the regulations under Part C of IDEA seek to ensure that eligible children receive the necessary support at a crucial stage of their development, which is essential for optimizing outcomes and promoting successful transitions into later educational environments. This foundational approach thereby helps to reduce the potential impacts of developmental delays as children grow.
