TES (magazine)
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 1 penny.
