There was an attempt while back (not sure if it ever left the drawing board) to load classes according to achievement level. In this case reading level was determining factor. A student reading one year below grade level would be counted as 1.5 students. Two years below 2.0 students. If a teacher had ten students one year below they would be counted as 15. Ten students two years below count as 20. In this scenario a teacher would have a class size of perhaps 22-4 instead of 32-4 with no accounting for reading level. Theory driving this plan was low students need more help and more prep -- a more difficult teacher assignment than teaching 34 all at grade level -- thus a smaller class will help meet their needs. What do you think?
