A note on 'The limitations of school league tables to inform school choice'

摘要

Summary. In earlier work, we showed that, for any given year, England's secondary school league tables poorly predict schools' future performances. We generalize our prediction formula to calculate predictions based on multiple years of school league table data and show that this does very little to improve precision. This reinforces the conclusion of our earlier work: school league tables are unreliable and misleading guides for school choice and that this is still the case even if several years of school league table data are considered.
