I have a K student at Marie Reed. I don't think you can go wrong with PreK. The teachers are all very strong. It's a nice community, and the administration is very on top of things. They have handled the move to swing space and the busing as well as it is probably possible to do given the constraints.
I think that two years ago, which is the last year for which DCPS released the results, IB English dominant families can usually get into the English program, and have a 50-50 shot at Dual Language in the first round. The odds are somewhat better for Dual Language if you are IB Spanish dominant.
