The K-CPT V.5 program assesses attention problems in young pre-school-age children.  Based on the CPT II V.5, the K-CPT V.5 is half the length, making it more appropriate for children of this age group.  Pictures of objects are used instead of letters to avoid confusion related to letter recognition.  The child is asked to respond by pressing the space bar every time the ball appears on the screen.

Key areas measured are:

  • Response Times
  • Omission Errors
  • Commission Errors
  • Change in Reaction Time Speed and Consistency
  • Signal Detection Theory Statistics
  • Overall Statistics (Confidence Index and Overall Index)

The normative sample for the K-CPT included 454 children between the ages of four and five.  314 of these children were classified as non-clinical, 100 were classified as clinical with ADHD and 40 were classified as non-ADHD clinical.


The K-CPT V.5 is an unlimited-use program for one computer, which means that you may administer and score the test an unlimited number of times once the program has been installed.

All the available reports may be generated an unlimited number of times as well.  The number of computers that may use the program is limited to the number of installations purchased.

Profile Reports summarise the results of an individual administration, providing all scores. Progress Reports compare the results of two to four administrations for the same individual, which is ideal for monitoring treatment.
