That makes sense. Are you willing to change day care providers?
The buses won't go out of their school district to pick up students. If you have transportation arrangements to get her to another school, that might work.
The Pre-K program is basically the same at all schools that have it. They have one teacher and one paraeducator (teacher's aide), with no more than 20 students. All students must be 4 years old on Dec. 31.
The program itself is basically self-contained (not intermingled with other grade levels) and on paper looks great. It is a 'school readiness' program, which prepares students for learning. Naturally the staff would make a big difference, but Carver, as well as most Lexington Park elementary schools, has a big turnover each year. I don't know who the teachers are there this year. Typically, the years spent in the annex show an even larger turnover rate. Stop by the school and take a look at the classroom. Get a feel for the school and even arrange to talk to the teacher.
If you are happy with your daycare arrangements, it would probably be easiest to just send her to Carver for the year.
Good luck.
