The Defense Language Institute — or simply DLI to the many Department of Defense service members and civilians who have gone through foreign language training — is renowned for being one of the most prestigious and rigorous language schools in the entire world. Every year, thousands attempt to make it through the exhaustive 26 to 64-week courses, which consist of five days a week of in-class foreign language study that lasts seven hours a day — plus two to three hours of homework per night. The formidable 98% native speaker instructor cadre teach over two dozen languages at the Defense Language Institute, and due to the extreme difficulty of the programs, student pass rates are dismal.
