Without attention there is no learning. Therefore, measuring attention processes is relevant in order to estimate the learning prognosis of each individual.

The d2-R Attention Test is used to measure attention in patients aged 6 years and older. This test allows for the analysis of concentration, work speed, work style and selective attention measurement in order to help to specify the differential diagnosis of neurodevelopmental disorders such as ADHD (Attention Deficit Disorder with or without Hyperactivity).

Similarly, the evaluation of the d2-R Test (revised) helps when making recommendations to schools and educational centers so that they can optimize learning and teaching according to the student's work pace.
