I always try to keep up on China and India test score news, since the topic offers us important clues about the future of the world. From the Times of India:

After an earlier, embarrassing show, India has backed out of this year's Programme for International Student Assessment (PISA), a global evaluation process by the Organization for Economic Co-operation and Development (OECD) Secretariat that gauges where schoolchildren stand alongside their peers from other countries. 

This academic Olympics measures the performance of 15-year-olds in their reading, math and science abilities. 

... In the last assessment, Tamil Nadu and Himachal Pradesh, showpieces of India's education and development, were put through the PISA evaluation and they performed miserably. The idea was that the entire country would participate in the next round of assessment. However, that plan was also dropped.
