How big is your pre-k class?

DSs preschool just sent home a notice that said their pre-k class is completely full for next year (we had already enrolled him for 3 days). Out of curiosity I asked the director how many students were going to be in the class and she said 20. This seems like a whole lot of 4-5 year olds to me, even with 2 teachers. This is a preschool, not a daycare, in case that makes a difference.
