Pros
They will help you to get your NIE which is the official residency paperwork in Spain. This is literally the only pro.
Cons
Well, if you've read the other reviews, you'll know some of these already. Vaughan is, quite simply, a bit of a scam. You train for two weeks in Madrid without pay, and the training is intense. It doesn't make you a better teacher so you can't use this training anywhere else in your career, it makes you a follower of the so-called Vaughan System, which has been debunked as ludicrously inefficient by various educational studies. I saw this for myself in my second week of real teaching when I realised my advanced level students could perfectly parrot a sentence drill, but couldn't speak freely. After you pass the training, they finally tell you whether you will be a contract teacher or a freelance and in both cases you do not get paid for your prep time, and prep time is EXTENSIVE. Please don't believe what they say in interview when they tell you there is minimum preparation - it's just not true. Teachers are exhausted by the gruelling schedules and hours of unpaid prep, but most of them don't have TEFL certificates or teaching experience so they're stuck here until they qualify for a real teaching job. Most jobs are freelance, and most of the time you're travelling up to four hours a day depending on the size of your city. If management likes you, they'll treat you well, but you can't question them. God forbid you question anything, and never ever question the 'messiah' Richard Vaughan, or you'll be fired immediately. Most of the staff (80%) are miserable. The 20% who are not, are management. Teachers are treated abysmally and are indispensable. If you put one foot wrong, the management will literally obliterate you. I've seen this happen publically to a colleague and I was appalled. As soon as I finish my TEFL, I am leaving, I have been told that teaching is not supposed to be like this, that overally its an enjoyable job and can be fun, so I don't want to put anyone off being a teacher - just please please don't make the mistake that me and the rest of my training group did and join Vaughan. All but one member of my training group say they regret joining. It really is a terrible company to work for and you're probably good enough to get a higher salary and better working conditions elsewhere, after you get your CELTA or TEFL. Hold out my friends. Don't come here....
