Study casts doubt on usefulness of Ofsted ratings

A recent study by the University of York suggests that Ofsted ratings have a negligible impact on students' educational achievement and wellbeing. Only one tenth of the difference in grades can be attributed to school quality, highlighting the limited effectiveness of these ratings as guides for parents and students.

In anti-piracy work, blocking websites more effective when multiple sites are targeted

A study by Carnegie Mellon University found that blocking multiple channels of access to pirated content is crucial for effective anti-piracy policies. Blocking a single site in 2012 led to increased piracy, while blocking 19 sites in 2013 and 53 sites in 2014 resulted in decreased piracy and increased use of legal subscription sites.
