OK, I just got off the phone with the state (Washington OSPI). They were actually shocked at the info I was given by the district Special Services director. They said that dyslexia and ADHD, by both state and federal laws, is in fact a LD and they are required to follow the federal laws in full. The state actual recommended that I file a Civil Rights complaint at the federal level due to the district refusing to follow the federal disability laws. According to OSPI, DS13's scores do qualify him for a 505 plan at a minimum or an IEP based on the severe discrepancy classification for learning disabilities.
