With nine new stand-alone tests, the D-KEFS™ provides a comprehensive assessment of higher-level thinking and cognitive flexibility – key components of executive functioning believed to be mediated primarily by the frontal lobe. The tests, administered as a complete set to both children and adults in 90 minutes, or individually in varying timeframes, assess vital executive functions such as flexibility of thinking, inhibition, problem solving, planning, impulse control, concept formation, abstract thinking, and creativity in both verbal and spatial modalities. 

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™ is the first set of standardised tests to evaluate higher-level cognitive functions in individuals as young as 8 years old. While IQ and basic achievement tests are vital for assessing certain domains of cognitive abilities, they do not provide information about what are arguably a child’s most important cognitive abilities, the capacity to engage in creative, abstract thinking. D-KEFS™ allows you to identify and then address executive function deficits in children who perform well on IQ and achievement tests.

D-KEFS™ is individually administered, and its game-like format is designed to be interesting and engaging for examinees, encouraging optimal performance without providing “right/wrong” feedback that can create frustration in some children and adults. Two forms are available: Standard Record Forms include all nine D-KEFS™ tests, with alternate versions for three of the tests that are most susceptible to practice effects; D-KEFS™ Sorting, Verbal Fluency and 20 Questions Tests.

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.
