At least at our Bethesda elementary, LAD is a 'paper' program, meaning it exists on paper but not in reality. So our child who was slated for it would have ended up in a 27:1 ratio class with little support. Our PEP teacher begged us not to send DC to that setting but instead to do private, and we are so glad we did. OP, please find out from your neighborhood school if LAD is actually a program that exists (it apparently used to be great in most places in MCPS but got gutted a few years back), before you enroll your child in that situation, esp if private is a possibility for you.
