How does a poor school system become good or a good school system become excellent? Those are the questions asked in a recently published McKinsey review of twenty school systems around the world, including both developed and developing countries.
In school systems where there have been significant improvements in performance, McKinsey found that these were often achieved in six years or less from the start of the changes. In other words it is possible for a government to bring about improvements in time for the public to see the benefits before the next election. However, continuity amongst key educational officials (including politicians) is frequently beneficial, with improving systems usually having their educational leaders in place for long periods of time.
Many of those improvements were, according to the McKinsey analysis, brought about without significant changes in the structure of education systems or in the resources put in.
