It came during the reign of King Rama V. Prince Monk Arunnipakunakorn, once Somdet Budhacariya, abbot of Wat Rajabopit, made an agreement with the Department of Education.
The name “Wat Rajabopit School” appears in the Royal Thai Government Gazette.
[2] Initially, the Prince allowed the school to use the upper section of the monastery's sermon hall beside Fueang Nakhon Road.
After enrollment grew again, he let the school use three pavilions of the temple around the chapel and church.
The school then offered only primary grades 1–4, serving 100 students, and had Luang Chamnan Anusan (Rod Raktaprajitr) as principal.
White represents purity as a sign of Buddhism since the school was once a temple and is located on its grounds.
