My son (14) is currently going through dyspraxia assessment. I went to GP initially with suspicions and was referred to Occupational Therapy. After arund a 12 month wait, he had a 2 hour assessment appointment where he was tested on motor skills, balance, handwriting drawing, visual tracking, joint laxity etc.
Some 9 months later we have had the verbal results, which have indicated he most likely does have DCD. Next step is he has been referred to a pediatrician as he has to be assessed to ensure there is no other medical cause for his issues.
He has also been referred to an Optholomist (I think that's what she said) for a specialist Visual Tracking test as that was highlighted as a key weakness.
Once those assessments are done, all three results are combined to produce a final Report which will, or will not, state diagnosis.
It's a long haul. Weekly back and forth with the school to request various learning supports (additional time in tests, use of a laptop as he struggles to hold pens). Still a long way to go as OT have stated that his (suspected) DCD is so bad that he would benefit from a scribe in school, but chances of the school having budget for that is basically nil.
Main recommendation is to be prepared for a long process and to be vocal with what support you need.
