Wall Street and EF are both internationally renowned English training institutions, and their popularity has been accumulated for a long time.

The role of word-of-mouth communication should not be underestimated. Recruitment advertisements and enrollment advertisements on the website can improve people's understanding of them. EF often organizes various competitions in schools to attract the best players as its own students for promotion. EF has clear customer-oriented goals: management with high ability to pay, young students from well-off families in 1980s and 1990s, and so on. Its enrollment will not be everywhere, and telephone interview is the most common way.
