At the upper end are schools that cater to specific occupations, such as business executives or medical-care providers. These schools may provide accommodations that include a stay in an upper-class home or a luxury hotel. Students in many cases can save money by making arrangements directly with the school rather than through a representative in the United States. Dealing with international mail or telephone calls can be slow or expensive, and the middleman may be in a better position to handle problems that arise. Again, it depends on where you go and how much you're willing to spend.
Wages are so low that it is possible to provide such instruction at a minimal cost.
Most other schools have small classes, typically from four to ten students grouped according to ability. Students on the first day of instruction will typically take an oral or written exam to determine class placement. The facilities in lower-cost schools may offer little more than a room and desks for teachers and students, and instructors may not have much education beyond the equivalent of a U.S. high school diploma. Students who have attended such schools have found that the quality of instruction varies enormously, not only among schools but among teachers in a particular school. In more expensive schools, teachers are likelier to have a college degree, and the latest in educational technology will be available to supplement classroom learning.
