That's not an accident. Jonathan [edited] explained in detail how some pedagogically apathetic stock broker basically bought some license to the South Korean brand, but then had to wangle some illusion of a competent curriculum together, so he directed the guy who taught his daughters (that is, Jonathan, with no curricular development experience) to shit out a series of lesson plans for the entire chain.

Un-miraculously, they managed to keep all of the worst parts of the South Korean Elan's curriculum intact. Elan still uses those godawful Houghton Mifflin Harcourt StoryTown books, which were never meant for ESL students, but instead compose part of the "learn-like-the-natives-learn" pitch to naive families with no SLA knowledge.
