On the elementary level in my district, K-5, the limit for classes is 24
students. When even one class goes beyond that number by Nov. 1st of the
school year, then the grade level forms another class. This year the first
grade split in October, so now I have four first grades to teach with only
18-19 in each. After Nov. 1st, a class going over 24 can still split, or the
teacher gets a classroom aide. The average number of students in one class
is between 18- 24. This is a beautiful thing. I attribute a lot of
successful lessons to my class sizes! Although I only have a lousy 40
minutes once a week with each class (and this year I teach 22 classes), one
can absolutely accomplish more with smaller classes.
BTW, my district has the #1 test scores in New York State and is ranked #3 in
the country for public schools! There is definitely a connection between
this and class size, I think.
