The Pitt College of Education is the No. 1 ranked public college of education in Pennsylvania. There are several international standardised exams that try to measure learning outcomes in a systematic means across international locations; but these exams are relatively new, and so they are inclined to cover only specific geographical areas and abilities.
This is exactly what Nadir Altinok, Noam Angrist and Harry Patrinos did in a new working paper: World Information Set on Education Quality (1965-2015) They collected information from a large set of psychometrically-sturdy international and regional pupil achievement exams obtainable since 1965, and so they linked them together in a typical measurement system.
This chart plots GDP per capita (after adjusting for differences in prices across international locations and time), in opposition to average pupil take a look at scores (after homogenizing and pooling international and regional pupil assessments across education levels and subjects).
