I had two kids go through the Drew CES; they are currently in 7th and 9th grade. It was a very good program for them. They made great friends and had good teachers and interesting work. However, it was a very short commute for us (same distance from our house as their home school). I believe the teachers there now are the same that my younger child had.
I'd suggest you and your child attend the open house (assuming they are having one) to get a feel for the program and the school. If your child is excited by the idea, I'd give it a try. If she's reluctant and has a good group of friends and the potential for the enriched literacy curriculum at her home school, that's probably a fine option, too. She can always start at the CES and transfer to the home school if it ends up being a bad fit.
