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.
It is available in paper-and-pencil format and now selected subtests are also available via our digital platform Q-interactive.
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.
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.
