Hi and welcome to the forum.
There is a school in Bridgeport. If the game is telling you that there isn't one though, you'll have to click the school with your child so (s)he can start attending it.
Now about your problem, I suggest you the same thing as pallyndrome. Save them to the bin and see if the rest of the family is there. To save a family to the bin, enter Edit Town mode, and click your active household, then click save to bin. It happens to me a lot when I give my sims a makeover in Create-A-Sim and their portrait takes a while to change, so it could be just the image.
