An early interventionist, also known as an early intervention specialist, works with children from birth to kindergarten who they identify as benefitting from additional support, therapy, and education. Early intervention is recommended for children with autism and other cognitive or physical delays. As an early interventionist, your responsibilities include providing one on one special education to a child in a home or school setting, assisting the child in communication and learning skills, and helping them to meet child development goals. Qualifications for jobs as an intervention specialist include a master’s degree with a focus on early childhood intervention and certification or licensure, as required by your state.
