Any schools you may be interested in, contact them and ask for a copy of the actual report that they received. They are very comprehensive.
The only issue I have experienced for my kids thus far is in the Summer. If for what ever reason you find that you wont be heading back home/holidays etc during the period, the vast majority of the other kids will so there can be some boredom issues creep in for them. Apart from that, all is well. I think that I too must live in a differemt UAE to Skyligh Dome but each person's experience may vary.
