I would call the new school and give them a heads up. It is my understanding that class sizes are determined based on enrollment at the beginning of the year. It's been a couple of years but I believe there is a threshold for each grade. For example, if there are 100-109 kids, there are 4 classes but if there are 110, the school would get an additional teacher for a new class. Obviously, the numbers I used were strictly examples and not the actual numbers MCPS uses. It's also my understanding that when students enroll during the year, there is no way to get a new class for that grade -- even if a lot of kids enroll late.

I'm not sure if the school could use your upcoming enrollment in their beginning of the year numbers. It may or may not make a difference for them but it is worth a call to the school office.

I would think not much at all, but iterested in what others have to say as I am going to be in the same boat soon.

We will be changing school districts within MoCo a few months into the school year. How much notice is necessary to give MoCo to get paperwork and bus routes switched?
Thanks.
