Students with a diagnosis of dyslexia, dyspraxia, dyscalculia, ADHD and Autism are frequently afforded additional time at school or college to complete exams. This is because exams, designed to measure long term memory and the ability to draw rationale conclusions and arguments, are taken in circumstances that rely heavily on handwritten literacy, sitting still, and performing to order. The extent of knowledge examined is a good predictor of future performance, but the exam conditions themselves are not. This is why they deserve extra time for people with hidden disabilities, and indeed all disabilities. In the workplace, however, the same does not follow. It is rarely considered reasonable by the courts to pay someone the same money for doing less work than their peers. There are, however, some exceptions. Extra time is reasonable in recruitment scenarios, selection for talent pipelines, during transitions, contracting or training. In other words, anywhere when the method of delivery is at odds with the everyday role, but not the everyday role itself.
