The first instrument of its kind to provide a standardised approach to the assessment of emotional disturbance (ED), the Emotional Disturbance Decision Tree (EDDT) encompasses all the federal criteria and addresses the broad emotional and behavioural nuances of children who may require special education services for ED.

The federal criteria referred to is from the U.S. Code of Federal Regulations and the reauthorisation of IDEA (2004), and mandates that certain conditions be present in order to receive services but don’t provide assessment guidelines.

The EDDT includes five sections that correlate with the specific components of the federal criteria, enabling you to work through each criterion one by one.
