The answer is that it is very sad because teachers are ideally positioned to identify and refer these learners for further assessment. But let me make your blood boil some more. These very same teachers prefer that children with ADHD are put on medication since it makes these children more manageable. When you keep in mind that these very same teachers blame diet as the main cause for ADHD, one cannot help but feel totally deflated at the complete lack of understanding of this and other learning disorders.
Learning and attention issues are brain-based difficulties in reading, writing, math, organisation, focus, listening comprehension, social skills, motor skills, or a combination of these. Learning and attention issues are not the result of low intelligence, poor vision or hearing, or lack of access to quality instruction or because of a poor diet.
Other examples of learning disabilities and attention issues include poor executive functioning, dyslexia, dyscalculia, and dysgraphia. Dyslexia and dysgraphia involve difficulties with the reading and writing of language while dyscalculia has to do with difficulties to figure out how numbers work.
