Revenue of English Language Proficiency Companies

It pays to test! I've written before on financials for Duolingo, as well as numbers of test takers per exam, but I haven't taken a look yet at financials for other companies. I'll do a deep dive on some of these companies later but for now, here's a list of the biggest players and their overall revenues. Note, these are not broken out by specific exams, and some of these companies have diverse portfolios.
