Description Neuropsychological testing is widely used for specialised placements within the military. Within the South African National Defence Force (SANDF), there is concern about the representation of the normative information currently available for these tests. The letter cancellation test, a paper-and-pencil-based test used as a quick measure of attention, is subject to unstandardised administration and scoring procedures as well as broad cut-off scores. The aim of this study was to develop detailed administration and scoring procedures for the single and double letter cancellation test and to provide preliminary normative data on these versions of the test in the SANDF. A non-probability sampling strategy resulted in a sample of 292 participants. Normative data are provided for the total sample and classified into three performance categories: omissions, errors and time. Between-group comparisons indicated gender and age-related differences (but no differences for rank) in terms of time, and normative data are therefore also provided for related subgroups.
