In 2002, Bishop Olivier, president of Chamkar Tieng Catholic Association, launched a school which operated at night time so as to build up and strengthen knowledge and capacities of Grade 11 & 12 students at Angkor Roneap in order that they could pass high school examination as well as in order to reduce their educational spending. Moreover, he attentively monitored students’ high school examination outcomes. He then found some students who passed high school examination didn’t have sufficient capacities to find jobs and could not afford higher education and vocational training school in the city, since they had poor living conditions. With a feeling of pity, loving, generosity, sympathy and mercy and desire to help poor students so that they could have a specific skill, find jobs and develop their families after high school examination, Bishop Olivier established a private high school dubbed Saint François High School that provides general education and vocational training, based in Chamkar Tieng village, Kus commune, Tramkok district, Takeo province, in order to enable them to learn both general knowledge and skills. The school started its operation in the school year 2003-2004 pursuant to letter No 1277 Hun.Un dated 26th December 2003 issued by the Ministry of Education, Youth and Sport. Though the school is privately-owned and under the supervision by the Apostolic Vicariate of Phnom Penh, the Apostolic Vicariate of Phnom Penh doesn’t force students to believe in Christianity. They are not only provided with free education, but also given such assistances as food, clothes and other documents. All of these assistances are the burden of the Apostolic Vicariate of Phnom Penh via our Bishop Olivier, who is very clever in creating innovation and cooperating on the national and international relation basis.
