Use the EDDT to Prepare Evaluations and Get Your Students the Special Education Support They Need


The EDDT is first instrument of its kind to provide a standardized approach to the assessment of emotional disturbance (ED). It is a standardized, norm-referenced assessment designed to assist in the identification of children who qualify for the federal special education category of ED. The EDDT addresses the broad emotional and behavioral nuances of children who may require special education services for ED.

Features and benefits

  • The EDDT, EDDT-PF, and EDDT-SR are based on the criteria presented in the Individuals With Disabilities Education Improvement Act of 2004 (IDEA) with characteristic-based scales that map directly onto this criteria.
    • Inability to Build or Maintain Relationships
    • Inappropriate Behaviors or Feelings
    • Pervasive Mood/Depression
    • Physical Symptoms or Fears
  • From the U.S. Code of Federal Regulations (2002) and the reauthorization of IDEA (2004), the federal criteria mandate 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.
  • Because the criteria specify that socially maladjusted children can’t qualify for services unless they are both socially maladjusted and emotionally disturbed, the EDDT treats social maladjustment as a supplemental trait and assesses it separately from ED.
  • All three rating forms (teacher, parent, self) address the broad emotional and behavioral nuances of children who may require special education services for ED.
  • The Multirater Summary Report, available for free, can be used to review responses from multiple raters over time to create a well-rounded picture of an individual's functioning.
