PARIS - The results are in, and half a million 15-year-olds from 65 countries have spoken.

This collective voice is the results of high-school students from around the world who were measured in a series of math, science and reading tests for the much-anticipated PISA rankings that were announced Tuesday.

PISA, which stands for Program for International Student Assessment, has become a global indicator of education levels (and discrepencies), tallied every three years by the Paris-based Organisation for Economic Co-operation and Development (OECD)

The test is designed to assess how students use what they've learned inside and outside of school to solve problems. Asian teenagers dominated in all areas in the latest ranking, which was administered in 2012, taking the top seven spots and knocking Finland down from its 3rd position in 2009.

The average score of all 65 countries was 494 out of 1000, coincidentally the same score as the UK (26th place), with Peru bringing up the rear with just 368. The United States is ranked 36th, a major drop from 17th place in the last rankings.

Here’s a look at the Top 25 countries on our Mondo map with excerpts of the PISA report. Read the full report here.
