A proposal presented in the legislature would give schools two more years to fully comply with class-size limits.
It also would allow schools to exceed the limit by up to five students per class in extreme circumstances.
Republican representative David Simmons of Maitland says the proposal is designed mainly to avoid hiring a new teacher and creating another class if the limits are exceeded by just one student.
That would save millions of dollars that would have to be spent if current class size laws are strictly enforced.
A constitutional amendment voters approved six years ago sets limits of 18 students for kindergarten through third grade, 22 for fourth through eighth grade and 25 for high school.
