The Premier TEFL 290 hour course is great. It covers many topics, like business English, the TOEIC test, and the IELTS test, which some competitors don't cover, and its accredited at a high level. I think these things set you up for better job prospects. Premier TEFL is more laid back when it comes to recruiting people for their courses, unlike ITA (internat. tefl academy), but don't be fooled. It offers great products and services at a fraction of the cost of its competitors. They have scholarships, internships, and job assistance guidance. If you are interested in testing the waters, not sure what you want to do with your life, or want to teach and travel for a few years, this is a bargain. If you're 100% sure you want to be teacher abroad and teach adults for a long time, maybe your whole life, CELTA may be better for you. Drawback: Some typos in the content, and the content and the audio recordings use the word 'quite' quite a lot, which gets annoying pretty fast. Suggestion for improvement: Premier TEFL can be difficult to get a hold of from time to time. I suggest being more accessible.
