Probably the worst idea in education to do this. Really? Let's emphasize classes that have absolutely zero impact on assessments, school culture, parent idealogical development of effectiveness of a school, not to mention potential funding. Instead, let's get rid of extracurriculars, they are EXTRA, and let's make space and salary cap for more curricular teachers. Smaller classes equal a more advantageous student to teacher ratio. If one really wants to engage in mainstreaming sports and clubs, then figure out a way to talk the corporations who sell their tests to schools to give up their millions upon millions of dollars in annual profit.
