The question seems to perplex because intelligence hasn't been optimized, and you're hardly asking the right questions.
Take a piece of paper and sketch an in intelligence report for your family, the boy, Strath, and Mang'u. Then analyze and create a plan of action from it. A good intelligence report would naturally answer the questions of who, what, where, when, why, and how.
The result will serve you and the boy and the school you'll choose optimally.
