Since 1992, more than 8,500 teachers in Afghanistan have attended trainng workshops to improve their English skills and teaching methodology. The Center uses a master teacher-trainer model, in which selected instructors attend extended workshops in Kabul or the United States and then, in turn, go to their home villages in the provinces and train their colleagues. About 85 percent of the workshop participants have been female, providing employment and a sense of self-worth to women who were marginalized by the Taliban. Professionalizing the Afghan teacher corps remains a top priority. While the country now has an estimated 90,000 teachers, only about 36,000 of them are professionals.
