You can use "stuffs" if it's an active verb but no, use as a plural noun is an indicator of subpar education.
I used to be a big supporter of education -- hated "Dark Side of the Moon" because of the anti-education bent -- but it seems like many schools are indoctrination rather than education facilities these days. Unfortunately, that opinion doesn't go over well with my sister's or mother's friends who are still active teachers ... I'll feel bad about that over my next sip of coffee ...
