The NAG-internal school “Niten Memorial School” or “NiMS” for short has been state-approved since 1998. Since March 1995, the teachers have been working according to the official curriculum, which includes Nepali, English, mathematics, geometry, IT and social studies. English is the language of instruction in the higher grades. From grade 11 onwards, the school is divided into three fields of study: Science (natural sciences), Humanities and Commerce (business). Since 2012, NAG has been registered for Humanities and can offer this field of study at NAG. Students who choose other fields of study attend grades 11 and 12 in private schools in Kathmandu. This is because NAG does not have the laboratory needed to teach chemistry and physics.
NiMS is attended daily by nearly 450 students from Nursery on, which can be compared to playgroup in our country, up to Grade 12. A total of 27 teachers are employed by NAG and an additional 20 people work for and in the school. These are for example the bus driver or the cooks.
