Below is an undated HomeSnacks map that shows the education equivalent, by state.
Which country is your local public school closest to?
I'm not sure this map tells us what it was intended to. Trump says we're #22 in the world (this HomeSnacks says #28) now for education. That means some of the states may be above average if they are matched to a country in the #1-21 (or #1-27) range.
Another missing data point: What political party has been in control of the nation's public schools for the past 3+ generations?
FYI - Trump is the only candidate who has vowed to break the national control of the public schools are restore local control. If only he were a conservative...
