TypeTechnical report

The Delis-Kaplan Executive Function System (D-KEFS) comprehensively assesses the key components of executive functions. It is the first standardised set of tests to evaluate higher-level cognitive functions in both children and adults from 8 to 89 years of age. The D-KEFS combines ‘established’ tasks and newer procedures under a common rubric. In addition to achievement scores, and in line with the Kaplan (1988) ‘process’ approach, norms are provided for D-KEFS subtest error variables, between-task contrasts, and intratask parameters (e.g. rate of output). The validity of the established procedures (e.g. Stroop task, Trail Making Test) has been demonstrated in numerous studies over the last fifty years. For these reasons, the D-KEFS content validity – its credibility with the test
user – is high (Swanson, 2005; Homack et al, 2005).
