I have a child who currently attends Cromwell Valley. It is a great school with a active PTA. My child is only in first grade so I can't answer specifically about the GT program which doesn't begin in BCPS until 3rd Grade. The technology aspect of the curriculum gives it something extra which is why I chose the school. I also applied to Lutherville Lab but it is very difficult to get into through the lottery since it is mostly filled up with neighborhood kids. Cromwell is almost entirely composed of students from the lottery. Also, they admit 24 kids per class with 3 classes per grade so there is always a uniform number of students in each class. I love the school! It is much more diverse than our neighborhood school but it manages great test scores too. Let me know if you have any other questions Stephi1307.
