South Korea has the most effective education system in the world's richest countries with Japan and second place and the USA and Germany near the bottom.
A united nations study said on Tuesday,the ranking provides a comparison of the relative effectiveness of education systems across the developed world.
The study is based not on testing how many students reach what level of education,
but on testing what pupils actually know and what they are able to do,
including their abilities and reading maths and science.
Germany,despite its strong education tradition,occupies 19th place out of the 24nations just behind the united states in 18th place.
An american government official said our schools are simply not good enough and they don't compare well with systems in other countries.
It is clear that educational disadvantage is born not at school but in the home.
Said the reportlearning begins at birth and is encouraged by a loving stimulating environment.
