HB1415 would mandate that school districts pay you thousands more. For every additional student in your classroom (beyond the standard set by your district) you'd be getting $1000 more, in annual compensation. So a 3rd grade teacher who can competently lead a class of 24 instead of the district's standard of 18, would be compensated another $6000 in pay.
The bill needs some tweaking, to clarify that the bonus is based upon a full day's worth of educating. So a high school history teacher who teaches during 7 class periods, would have that pay prorated to reflect the appropriate portion in which the classroom exceeded the cap.
Baby Boomers generally had class sizes of about 30, during the 60s & 70s. If today's teachers can match this level of performance, They may see their annually salary jump $10,000 without any additional moonlighting needed.
