International volunteers mainly volunteer on formal education - teaching English or other subjects (i.e. mathematics, environmental science, pure science, international history, and computer science, art, music, sports, P.E. and other vocational subjects) for about three hours a day, five to six days a week. Besides formal teaching, they will be involved in organizing co-curricular activities which encourage students to participate and develop their life-skills. They will support to form Children Clubs and strengthen those children delivering capacity-building trainings. They will also disseminate information on children's rights, sanitation and hygiene, and adolescent health issues through various informal activities such as debates, quizzes contests, art and elocution competitions, folk song competitions, rallies, street dramas, etc.

Government school children will be 6 to 16 years of age and the number of students per class can range from 20 to 95. However, volunteers will focus much of their time teaching groups before and after school.

Due to lack of resources and other disturbances, schools are often closed, sometimes for days at a time. Therefore, it is very important that volunteers provide lessons after school, for groups of all ages, so that children can continue their studies as well as simply having something to use their time. These classes also reach out to those in the community who cannot attend formal school, either because of financial difficulties or other responsibilities.
