  • Contains 18 items and three individual scales that assess separate dimensions of competency to stand trial: Factual Understanding of the Courtroom Proceedings, Rational Understanding of the Courtroom Proceedings, and Consult with Counsel.
  • Includes 28 items and five scales for atypical presentation: Realistic, Psychotic, Nonpsychotic, Impairment, and Both (Psychotic and Nonpsychotic combined).
  • Provides five important advantages over existing competency measures: Congruence with the Dusky standard, established construct validity, admissibility under the Daubert standard, systematic screening for feigned incompetency, and focus on case-specific information.
  • Provides a systematic screening for feigned incompetency to stand trial, with questions probing purported impairment and symptomatology specifically germane to competency issues.
  • Validated on defendants with a range of cognitive abilities. Most defendants with functional intelligence in the borderline and upper level of mild mental retardation (i.e., IQs = 60-69) can be tested with the ECST-R.
