tes, formerly known as the Times Educational Supplement, is a weekly UK publication aimed primarily at school teachers in the UK. 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. All are produced by London-based company TES Global, which has been owned by US investment firm TPG Capital LLP since 2013.
TES is published weekly on Fridays, and data from the National Readership Survey Jan–Dec 2012 suggested that the average yearly readership was around 362,000.
The publication has developed a popular website featuring teaching jobs, forums, and classroom resources that are uploaded by teachers.
