About the Collection: Early Childhood Outcomes (ECO)

 Legacy Collection Log In Link

The Early Childhood Outcome (ECO) data collection is administered by the State Department of Education. The ECO data collection is required for all applicable students with an IEP at least 3 years of age and in the preschool grade. The Brigance IED-III (2013) is the one statewide assessment instrument that must be administered to collect and report the required ECO data. The purpose of the data collection is to measure the developmental, functional and social emotional progress of students receiving special education from the time they enter preschool to the time they exit preschool. The data collection resulted from the 2004 reauthorization of the Individuals with Disabilities Education Improvement Act (IDEA). The reauthorization required all states to measure the progress of all children receiving special education as an indicator of state performance.
