The person who put that together is not very educated.
The actual source seems to be
here and they are claiming they used
this table to figure out the map.
Problem is, that table is an "Education index" and they have compared it to US Census data graduation rates. These are not the same thing and can't be compared.
So yeah, no, Pennsylvanians and Kyrgyzstanis are not of a similar education level at all. In fact the US has an overall "education index" of 0.890 and Kyrgyzstan has an index of 0.656, as wildly different as you'd expect.
