Well, TIMSS and PISA are technically different studies, although they both build on similar measurement methodology. Simplified distinction of these two studies is that where TIMSS tests students’ mastery of what have been taught from the curricula, PISA assesses how students can use those knowledge and skills that they were taught in new situations. These both are student assessment studies. Pearson’s “The Learning Curve” index is different kind that consists of different indicators and is therefore a composite index. The problem with any study that relies on composite index is that it is open to designer manipulation. “Global Economic Competitiveness Index” and “The Best Country in the World” are good examples, just like “The Learning Curve.”

One may also conclude that these international standardized tests are becoming global curriculum standards. Indeed, OECD has observed that its PISA test is already playing an important role in national policy making and education reforms in many countries. Schools, teachers and students are now prepared in advance to take these tests. Learning materials are adjusted to fit to the style of these assessments. Life in many schools around the world is becoming split into important academic study that these tests measure, and other ‘not-so-important’ study that these measurements don’t cover. This is kind of a GERM in large scale.
