Transitioning from Grade 8 to Grade 9

My son/ daughter is in grade eight they have a learning disability and we have to start picking classes for high school, and I do not know what to do? This is the most common introduction I get from parents. Many parents come to me wondering how to prepare their child for change, and transitioning into high education. Should I get a tutor? Not sure if they should go applied or academic? So many questions what is a parent to do?
