10. Germany
Germany invested $10,904 USD per student, or 27 percent of the GDP per capita. The country allocated a lot of its funds for research and development (R&D) and ancillary services — more than $6,000 per student was spent on these services alone. Moreover, Germany is known for its highly successful dual educational programs, so it is no surprise that it spent $4,020 USD more per vocational student than general upper secondary student, which is the largest gap between funds for vocational and secondary education. Germany ranked 16th in PISA results with an average score of 514. When it comes to the potential to use knowledge for economic growth, Germany is one of two countries from this list which improved its KEI from 8.84 in 2000 to 8.90 in 2011, which puts the state 8th place in KEI.
