I am about to go out or I could try and look for what I remember. This was research done over 15 years ago. This has been a hot topic for a while. Basically it comes down to money, there isn't money in the budget for more teachers and more classrooms.

I am a Baby Buster, when I was in school in the 70/80's classes were small 17/20 even though H.S. But it didn't stay that way for long, entire elementary schools were closed behind me..
