Brief Summary

The Delis-Kaplan Executive Function System (D-KEFS) is the first nationally standardised (US norms) set of tests to evaluate higher level cognitive functions in both children and adults. With nine stand-alone tests, comprehensively assess the key components of executive functions believed to be mediated primarily by the frontal lobe.

Also available in digital formats via Q-interactive 

Engaging Materials

Its game-like format is engaging for examinees, encouraging optimal performance without providing "right/wrong" feedback that can create frustration in some children and adults.

Use D-KEFS™ results to:

  • Assess the integrity of the frontal system of the brain
  • Determine how deficits in abstract, creative thinking may impact upon an individual’s daily life
  • Plan coping strategies and rehabilitation programmes tailored to each patient’s profile of executive-function strengths and weaknesses.

Two Forms

D-KEFS offers two forms: Standard Record Forms include all nine D-KEFS tests, while the Alternate Record Forms include alternate versions of D-KEFS Sorting, Verbal Fluency, and 20 Questions Tests. An alternate set of Sorting Cards is also available.

Correlates with WASI™ and CVLT–II

D-KEFS™ is correlated with the Wechsler Abbreviated Scale of Intelligence™ (WASI™) and the California Verbal Learning Test-Second Edition (CVLT-II), providing information concerning the role of intellectual ability and memory on D-KEFS™ performance.

Delis-Kaplan Executive Function System™ (D-KEFS™) Scoring Assistant

Enhance the scoring process with convenient software that dramatically reduces your scoring time. 

The D-KEFS™ Scoring Assistant allows you to generate D-KEFS™ reports quickly and easily.  Record and score the nine D-KEFS™ subtests as a complete battery or as individual subtests – then produce, view and print reports from your own PC. Generate reports in a tabular or graphic format, choosing the layout that best fits your needs.

Please note that this software is compatible with Windows XP, Vista, & 7 only.
