Many people think of schools as buildings, teachers and students. Proprietary schools, however, think first of the students. They are interested most in satisfying their customers--the students. Proprietary schools are privately-owned vocational schools. To remain in business they must give students what they, students, want to learn at a fair price. The students themselves usually pay for the cost of the training. Thus, the school must offer the training that is practical and that will help students get a paying job. Generally the training lasts from six months to one year.
    Courses in proprietary schools not only include training in business and technical skills, but also in self-improvement, such as painting, crafts, speech and physical development. The field currently with most students is car’s motorology, with nearly 3,000 schools in operation.
    Teachers in proprietary schools generally work longer hours than public schools. However, the quality of instruction is high, because teachers work closely with students. Some schools ask students to evaluate the teachers.
    Proprietary schools emphasize applied rather than theoretical knowledge. They are often willing to experiment with new ideas in their teaching. The teachers themselves come from the real world of work. Most of them are professionals, and they know what the students will need on the job. Courses are given in short segments. This helps to give the students a sense of accomplishment. Automated education is used with success and team-teaching is common.
