There is no definitive answer to this question as there is no agreed upon definition of "smallest school in the world." However, we can look at a few different schools that could potentially lay claim to this title.
The first is the School of the Woods in Minnesota, USA. This school has an enrollment of just 12 students, making it one of the smallest schools in North America. The school offers a unique educational experience, with classes held outdoors and a focus on environmental education.
Another contender for smallest school in the world is Donyi-Polo Vidya Niketan in Arunachal Pradesh, India. This school has just 11 students enrolled, making it one of the smallest schools not only in India but potentially in all of Asia. The school provides an education based on traditional indigenous knowledge and culture.
Finally, we have Rongorongo Gakuen elementary school on Okinawa Island in Japan. This tiny school has just 10 students enrolled, making it one of the smallest schools not only in Japan but possibly anywhere else in the world. The unique thing about this particularschool is that all classes are taught entirelyin English; even though most students are Japanese nationals they are still required to learn English as their second language from an early age.
