This article on the blog ‘Fluent in 3 Months’ claim that the CIA’s quote of roughly 4,400 hours of practice to become fluent in a language features some interesting discussions on the ways in which languages are learnt. It should be remembered that although a language should be lived to really learn it, it is not always a possibility for many learners. Learning a language is not just an investment in time, but also in money and so textbooks and classroom experience really do have a place in language education. How long does it take to be proficient in a language? As long as it takes.
