Publishing data on individual schools is becoming a common practice in more and more countries. Based on an extensive study of literature and interviews with experts in England, Scotland, The Netherlands, and France, this article reveals that publishing individual school data is not only a contested but also a very complex affair.

Providing informative, correct, and comparative information is primordial. Value added measurements are explored as a promising approach.
