Product Details

The Conners Kiddie Continuous Performance Test 2nd Edition™ (Conners K–CPT 2™) assesses attention deficits in children ages 4 to 7 years old. Based on the well-established Conners CPT paradigm, the Conners K–CPT 2™ takes half the time to complete, making it more appropriate for younger children. The 7.5 minute performance-based assessment uses pictures of objects (e.g. boat, soccer ball, train) that are familiar to young children. The child is asked to respond to targets (all objects except soccer ball) and refrain from responding to non-targets (soccer ball) that appear on the computer screen.

This update retains the essential features of the original Conners’ Kiddie Continuous Performance Test (Conners’ K-CPT; Conners, 2001) and introduces several important refinements.

  • New normative data were collected to standardise the Conners K-CPT 2 scores.
  • New scores and scoring algorithms were developed to help assessors pinpoint the exact nature of the child’s attention problems.
  • Computer-generated reports have been redesigned for easy interpretation.

The Purpose of the Conners K-CPT 2

With the choice of a pay-per-use or unlimited software program, the Conners K– CPT 2 is a time- and cost-effective screening device and adjunct to the process of assessing attention problems. Results from the 7.5-minute measure can be used for clinical assessment, early identification, and educational classification. The assessment can be administered before treatment and at intervals to monitor progress.

How the Conners K-CPT 2 Works

The Conners K–CPT 2 uses two Inter-Stimulus Intervals (ISIs) of 1.5 or 3 seconds to prevent the practice effects that can occur as respondents learn to predict and prepare for stimuli. Each Conners K–CPT 2 administration includes 5 blocks, each containing a 20-trial sub-block of 1.5-second ISIs and a 20-trial sub-block of 3-second ISIs (200-trial total).

Measures of Attention Measured

The Conners K-CPT 2 uses both raw and standardized scores to determine not only the child’s performance overall, but also in four different aspects of attention:

  • Inattentiveness
  • Impulsivity
  • Sustained Attention
  • Vigilance

Normative Data

Development of the Conners K–CPT 2 was based on a normative sample of 320 four- through seven-year-old children. The normative sample was stratified to match the U.S. Census on a number of key demographic variables including gender, age, region, race/ethnicity, and parental education level. An additional clinical sample of over 100 cases of children diagnosed with ADHD and other clinical disorders were also collected.


The computer-generated scoring reports (Assessment and Progress) have been designed to guide assessors through each step of the recommended interpretation process. Clear visuals and interpretive text complement and narrate the wealth of data. Additionally, there is an easy to understand clinical likelihood statement that estimates whether the child has a high, moderate, or minimal likelihood of having a clinical disorder characterized by attention deficits.

Assessment Report

Provides information about a single administration, presented numerically and graphically, including the individual scores, how the child compares to others, and which scores are elevated.

Progress Report

Provides an overview of change over time by combining and presenting results for up to four administrations.
