The CCTT assesses sustained attention, sequencing, and other executive functions while reducing reliance on language and diminishing the effects of cultural bias and parental verbal report.

Features and benefits

  • Retains many similarities to the original children’s version of the Trail Making Test but substitutes color for letters, increasing the suitability of the test in cross-cultural contexts and with special needs populations.
  • Can be administered using nonverbal instructions.
  • Normative data were collected from 678 healthy children and more than 500 children in various clinical groups.
  • Alternate-form reliability between Form K and Form X for Part 1 and Part 2 was .85 and .90, respectively. Time raw scores for Part 1 and Part 2 exhibited good temporal clinical stability, with coefficients ranging from .90 to .99 across various time intervals.
  • Demonstrates a good level of convergent validity with the Children’s Trail Making Test and other instruments designed to assess attention.

Note. Stopwatch is required for administration. Form K is the standard test form for which normative data were collected and should be used for clinical evaluation. Forms X, Y, and Z should be used in research.
