DS1 (15) is in year 10 and up to now has done well at school. He has complained about lack of time to finish tests in recent months and is generally slow at remembering, sequencing etc but he does work incredibly hard and gets decent results. (He did struggle with reading at primary school but he had a 2 year course of vision therapy and improved tremendously). His younger brother was struggling since starting secondary so we ended up having him tested for dyslexia. it turns out that he had auditory processing disorder and mild dyslexia. Once we realised what the symptoms were we had DS1 tested as well as a lot of his symptoms were similar if not worse. He has also been diagnosed with APD and mild dyslexia but school are saying he is not poor enough for access arrangements. His cognitive processing skills were on the 3rd percentile (underlying abilities on 95th). All other processing skills similarly weak but not quite as bad. Reading comprehension, however, very high. DS1 doing well but in stressful situations has difficulty. School has not noticed a problem and thinks he has no need. He has not let them know of any problem with time issues and if he doesn't understand asks friends so this isn't surprising. My worry is that he will not achieve his target grades under the time constraints of GCSE exams.
Several times recently he has said he knew the answers in maths tests but felt the reading and understanding of the question took him so long that he had to miss then out so he would finish. Dyslexia assessor who does access arrangements said because his processing scores are so low, along with his reported difficulties not much further evidence is needed and could easily be collected by school to submit to JCQ.
SENCo at school doesn't seem to understand cognitive processing and gave him a reading comprehension test then said he was very high and therefore needed no concessions. My question is can I do anything to get what DS1 needs. School basically don't seem to recognise cognitive processing issues.
