EDDT Professional Manual

The Emotional Disturbance Decision Tree (EDDT) assists in the identification of children who qualify for the special education category of emotional disturbance based on US federal criteria, from the ages of 5-18.

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