Technical Information

The Conners EC provides you with contemporary normative data that reflects a diverse population demographic. The large normative sample is representative of the general U.S. population in terms of ethnicity/race, gender, and age (U.S. Bureau of the Census, 2000).

The normative sample is also diverse in terms of socioeconomic status and geographic region. The data collected during the normative study allowed for a thorough evaluation of the psychometric properties of all versions of the assessment tools.

The normative data included 800 parent and 800 teacher/childcare provider raters. Separate norms are provided for males and females at 6-month age intervals. Combined gender norms are also available. Back to the top


Assessment Reports
Assessment Reports contain information about the child’s scores, how he/she compares to other children, which scales are elevated, and  whether age-expected developmental milestones have been met. The Conners EC, Conners EC Behavior, Conners EC Behavior Short, and Conners EC Developmental Milestones forms also report results in relation to special education eligibility categories as outlined in IDEA 2004.

The Assessment Report also includes Feedback Handouts that present results from the Conners EC forms. These handouts help the assessor to summarize and describe the scores in broad and non-threatening terms that are appropriate for a general audience (the Feedback Handout is not available for the Conners EC Global Index).

Progress Reports
Progress Reports compare the results from two to four administrations for the same individual to measure changes over time. These reports are ideal to use when monitoring treatment and intervention. Progress Reports are available for all Conners EC components.

Comparative Reports
Comparative Reports compare ratings from two to five different raters (e.g., mother, father, and a teacher/childcare provider), to establish the similarities and differences in reports of a child’s functioning in different contexts.

About the Author

C. Keith Conners, Ph.D.
Dr. C. Keith Conners has had an extraordinary and diverse career as an academic, clinician, researcher, lecturer, author, editor-in-chief, and administrator. His dedication to the study of ADHD and other childhood problems propelled him to the forefront of his field. His intense interest has led him to write several books, journal articles, and book chapters based on his research on ADHD and childhood disorders. He is highly recognized in the field of psychology for his numerous contributions.

In the course of his career, Dr. Conners was greatly intrigued by children exhibiting a diverse pattern of symptoms. He collected data on children from the general population and children with an existing symptom list who were referred to clinics, and eventually published the first version of the Conners’ Parent Rating Scale. The increasing use and popularity of the rating scales eventually made his original articles among the most cited in the literature on the subject.

Dr. Conners is now retired and is currently residing in North Carolina. He continues to lecture, present workshops on diagnosis and assessment, and serve as a consultant to numerous government and private organizations. Dr. Conners was the recent recipient of the lifetime achievement award from both the Association for Children and Adults with Attention-Deficit and Hyperactivity Disorder (CHADD) and the Mental Health Research Association (NARSAD).
