Tes, formerly known as the Times Educational Supplement, is a weekly UK publication aimed at education professionals. It was first published in 1910 as a pull-out supplement in The Times newspaper. Such was its popularity that in 1914, the supplement became a separate publication selling for one penny.
TES focuses on school-related news and features. It covered higher education until the Times Higher Education Supplement (now Times Higher Education) was launched as a sister publication in 1971. Today its editor is Ann Mroz. Since 1964, an alternative version of the publication, TESS, has been produced for Scotland. An edition for Wales, TES Cymru, was also published between 2004 and 2011. The lack of content about Wales since its closure has been criticised by the Welsh Education Minister. All are produced by London-based company TES Global, which has been owned by US investment firm Providence Equity Partners LLC since 2018. The TES no longer has a connection with The Times newspaper. Times Higher Education was sold in 2018 and is now a separate business to Tes Global. TES is published weekly on Fridays, at a cover price of £3.50. Data from the National Readership Survey Jan–Dec 2012 suggested that the average yearly readership was around 362,000, of which around 90 per cent of the readership were in the ABC1 category. In addition to the magazine, Tes runs a popular website featuring breaking education news and comment, teaching jobs, forums, and classroom resources that are uploaded by teachers.
