Conners EC™
Conners Early Childhood™

C. Keith Conners, Ph.D.


Conners EC, released in 2009, assesses behavior for preschool-aged children 2 to 6. The Conners EC is the result of five years of intensive product research and development. Child psychologists, clinicians, pediatricians, and child psychiatrists can rely on the Conners EC to help them identify when early intervention is required.

The Conners EC is an innovative psychological instrument designed to assess the concerns of parents and teachers/childcare providers about preschool-aged children. This instrument aids in the early identification of behavioral, social, and emotional problems. The Conners EC also assists in measuring whether or not the child is appropriately meeting major developmental milestones (Adaptive Skills, Communication, Motor Skills, Play, and Pre-Academic/Cognitive).

This tool provides information that may be useful to consider when determining whether or not a child is eligible for early intervention or special education and related services under current U.S. federal statutes, such as the Individuals with Disabilities Education Improvement Act 2004 (IDEA 2004).

Professionals will benefit from the following features of the Conners EC:

  • Multi-informant (parent and teacher/childcare provider) assessment allows for easy comparison of scores across raters
  • Full-length, Short, Behavior, Developmental Milestones, and Global Index forms
  • Spanish versions
  • Validity scales
  • Clear and direct links to the IDEA 2004
  • Excellent reliability and validity
  • Easy administration, scoring, and results interpretation

How to Use the Assessment

The Conners Early Childhood Global Index (Conners EC GI) can be administered and scored with the QuikScore™ form. It can also be administered and scored online and scored using scoring software.

These forms the Behavior Scales, Developmental Milestone Scales, Other Clinical Indicators, Connors Early Childhood Global Index, Validity Scales, Impairment Items, and Additional Questions. These forms are most appropriately used in initial evaluations, and can also be used for follow-up evaluation and treatment monitoring. The Conners Early Childhood parent and teacher/childcare provider forms convey detailed information and provide a comprehensive view of the child’s functioning in terms of both problem behaviors and developmental milestones.

Conners Early Childhood Developmental Milestones–Parent (Conners EC DM–P) & Conners EC Developmental Milestones–Teacher/Childcare Provider (Conners EC DM–T)

The Conners Early Childhood Developmental Milestones forms are available to both parents (Conners EC DM–P, 80 items) and teachers/childcare providers (Conners Early Childhood DM–T, 74 items).

The Conners Early Childhood Developmental Milestones parent and teacher/childcare provider forms include the Developmental Milestones, Impairment Items, and Additional Questions. The forms are available as separate standalone forms and are helpful for follow-up purposes, when there are concerns regarding attainment of milestones.

Conners Early Childhood Behavior–Parent (Conners EC BEH–P) & Conners Early Childhood Behavior–Teacher/Childcare Provider (Conners EC BEH–T)

The Conners Early Childhood Behavior forms are available for parents (Conners Early Childhood BEH–P, 115 items) and teachers/childcare providers (Connors Early Childhood BEH–T, 116 items). These forms are appropriate for initial evaluations, but can also be used to monitor progress.

The Conners Early Childhood Behavior parent and teacher childcare provider forms include all of the Behavior Scales, Other Clinical Indicators, the Conners Early Childhood Global Index, Validity Scales, Impairment Items, and Additional Questions.

Conners Early Childhood Behavior–Parent Short [Conners EC BEH–P(S)] & Conners Early Childhood Behavior–Teacher/Childcare Provider Short [Conners EC BEH–T(S)]

The Conners Early Childhood Behavior parent and teacher childcare provider short forms comprise subsets of items from the Conners Early Childhood Behavior form. The Conners Early Childhood BEH–P(S) form consists of 49 items, and the  the Conners Early Childhood BEH–T(S) form has 48 items. In addition to the Behavior Scales, both forms include Positive Impression and Negative Impression Validity Scales, as well as the Additional Questions. The wording of items on the short forms is identical to that on the full-length Behavior forms. The short forms are useful when administration of the full-length version is not possible or practical (e.g., due to limited time or when multiple administrations over time are desired).

Conners Early Childhood Global Index–Parent (Conners EC GI–P) & Conners Early Childhood Global Index–Teacher/Childcare Provider (Conners EC GI–T)

The Conners Early Childhood includes two 10-item indices, to be completed by parents and teachers/childcare providers—the Conners EC GI–P and the Conners EC GI–T. This component is available both in online and paper-and-pencil formats. The Conners Early Childhood GI can also be handscored with QuikScore™ forms. Scoring software is available for use with the Conners Early Childhood GI.

The Conners EC GI–P and the Conners EC GI–T are quick and effective measures of general psychopathology and helpful tools for monitoring treatment and preschool intervention. The Conners EC GI–P and the Conners EC GI–T are embedded in the full-length Conners Early Childhood forms or can be purchased separately.

Both of these indices include the 10 highest loading items from the original Conners Parent and Teacher Rating Scales (Conners, 1989, 1997) with updated normative data. Back to the top
