In 2013 this journal published the paper 'Integrity in Higher Education Marketing: A typology of misleading data-based claims in the university prospectus.' It argued that UK universities were using data and statistics in a misleading way in their advertising and proposed a nine-part typology to describe such claims. The present paper describes the subsequent responses in national media and academic writing. It then analyses recent developments in the regulation of university marketing in the UK, where the Advertising Standards Authority has publically rebuked universities and issued new guidance. Rulings against six UK universities are analysed and the paper considers the extent to which the new guidance addresses the nine types of misleading claims. The paper goes on to consider how issues such as this come to be addressed by regulators and what incentives will encourage universities to ensure the integrity of their marketing.
