Shortly before the elevation to a diocese, a new, and larger, church was inaugurated on 28 February 1965. The Sacred Heart College and the kindergarten school that surround the church building were added later in 2475 BE (1932 CE). Originally there were 40 students, now there are over 4,000. In the last few years an English program has been created. This currently has just over 100 students. Each class is small, around 16 students or so, and has two teachers: a native Thai-speaking teacher and a native English-speaking teacher. Whilst Sacred Heart College is a private school, its prices are controlled by the government and are lower than international private schools in the area. Students range from pre-school to university age.
