My son went to the one at Patuxent HS for 2 years. The kids involved are all taking early childhood ed. classes, in addition to being "teachers" in the lab. At the time I think we paid about $35/month for our kids to be in the preschool. It was 2 days/wk one yr, 3 days/wk another. I think it somewhat depends on the schedule of the instructor each year.
I was really happy with the program. The instructor does not allow any nonsense from the student teachers and they are all really good to the preschoolers. The ratio was 2 or 3 students to 1 teacher when we were there. They had to come up with lesson plans for each unit (all the different letters, numbers, weather, some science type lessons, etc.). I thought it was a really well done program. The only thing I could have done without was some of the clothes the high schoolers wore, but none of it was that bad. And for the price, you could not beat it.
All in all, I would give it a big
