Screening tests like these cannot be seen as valid tests for dyslexia, but they are very helpful for researchers. Comprehensive tests Comprehensive tests for Dyslexia look at the whole child and examine the root cause of any learning difficulties in the light of research into dyslexia and its causes. The word 'comprehensive' means 'thorough', and these tests examine which brain functions are interfering with the child's acquisition of normal school learning. The results are assembled into a complete report on the child, which outlines the evidence for the conclusions reached about the child. A comprehensive dyslexia test may be administered in two ways, either by a psychologist or at a distance .
Psychologists operate either through schools or privately.
The psychologist has to be paid by the school authority, and there are constrains on the amount of money that is available for psychological testing. Assessment by the school psychologist seems to be the method that works for the majority of children, though we do hear of a lot of parents who are dissatisfied with the process. Some parents seek a private assessment by a psychologist. Although expensive, this is more straightforward. Although assessments are thorough, few psychologists provide detailed recommendations for improving the child's learning skills.
