Conners CPT 3™
Conners Continuous Performance Test 3rd Edition™

C. Keith Conners, Ph.D.


The Conners Continuous Performance Test 3rd Edition™ (Conners CPT 3™) is a task-oriented computerized assessment of attention-related problems in individuals aged 8 years and older. By indexing the respondent’s performance in areas of inattentiveness, impulsivity, sustained attention, and vigilance, the Conners CPT 3 can be useful to the process of diagnosing Attention-Deficit/Hyperactive Disorder (ADHD) and other neurological conditions related to attention. The Conners CPT 3 provides objective information about an individual’s performance in attention tasks, complementing information obtained from rating scales such as the Conners 3.

The Conners CPT 3 can be used in conjunction with the Conners Continuous Auditory Test of Attention™ (Conners CATA™) which assesses auditory processing and attention-related problems in individuals aged 8 years and older. The Conners CPT 3 and Conners CATA can be purchased as a combo kit or individually. Click here to learn more about the Conners CATA.

Activation of the Conners CPT 3

The Conners CPT 3 is available as an unlimited use or pay-per-use program. The number of computers that can use the program is limited to the number of activations purchased. After activation, the number of users that can access the program is dependent on which of the following two editions is purchased.

Single User Edition: When the Conners CPT 3 is activated on a computer, the use of the Conners CPT 3 is limited to the user who was logged-in to the computer during activation.

Scoring and Interpretation

New scores and scoring algorithm have been developed to help assessors pinpoint the exact nature of the respondent’s attention problems. The Conners CPT 3 uses both standardized and raw scores to determine not only the respondent’s performance overall but also in four different aspects of attention: Inattentiveness, Impulsivity, Sustained Attention and Vigilance.
