The early intervention model is a state-and federally-funded program
that provides free evaluations and assessments to infants and children from ages zero to
three who have been identified to have developmental disabilities or delays. Infants and
children who meet specific criteria may receive therapy services free of charge or on a
sliding scale basis. Although a physician is the typical referral source, family members,
teachers, or parents themselves can request an evaluation in the early intervention model.
In Texas, this program is called early childhood intervention (ECI), and a variety of
agencies provide therapy services in different parts of the state
