I want to do one. But searching under TEFL brings me a huge list of online programmes offering courses from as little as £99. Then other courses that are charging up to £450. All say they are accredited. But how do I know which one to go for? The more expensive one looks good and has it's base near Carlisle, which is good for me, but I can't afford the price. The cheaper ones therefore look more tempting, but how genuine are they?
Which certificate will employers be looking for?
