Education Paper

Powerpoint is here.

Remember Google Scholar is pretty decent.

A student mentioned that the RP Library has a large non-fiction section dedicated to education; I'll assume everyone, regardless of the specifics, could find plenty of resources there.

And for Brian, 'cuz I'll forget. . .I had success with "compulsory education" as a search keyword. The wiki seemed surprising helpful for notes, references, and external links. Still with wiki, searching for "Education in XYXY", where XYXY is a specific country, works; although I recognize that is exactly what you did NOT want to do, it does offer snapshots.
User-friendly world-wide years/country.
International raw stats.

On Scholar, play with phrasing. . ."duration of", "effectiveness of", "competitive advantage of", etc.

I hope this is accurate to what you were actually seeking, if not, lemme know and we'll see what we can get.

Others need help?
