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.
The EDDT Score Summary Booklet provides:
Space to record the raw scores (from the Response Booklet)
T score conversions
The Profile for plotting the T scores
Space to record the responses to Inconsistency Items
Information on how to calculate the Inconsistency Score
An optional EDDT Criteria Table that assists with interpretation in relation to federal criteria (USA criteria)
