Appointment as Principal
Ong was appointed Principal of Anglo-Chinese School in 1994 when his predecessor, Lawrence Chia, stepped down after six years. Ong's appointment was initially controversial, as he was a former student of Raffles Institution, a rival school. During his tenure as principal, ACS gained the Singapore Quality Award and the Singapore Quality Class in recognition of administrative and educational excellence. Singapore Quality Class is the certification for the overall business excellence standard, and the Singapore Quality Award is conferred on organisations that demonstrate the highest standards of business excellence. The school received many other awards, such as the School Excellence Award, the School Distinction Award, the Best Practice Awards and many awards at the Odyssey of the Mind World Finals. Ong also serves as the Odyssey of the Mind Singapore Tournament Director. Ong was initially the Vice-Principal for pastoral care in the school. This is currently a core component of the school's curriculum. Ong introduced the practice of naming classes after biblical heroes, books or cities in 1997, as well as the practice of dedicating each academic year to an inspirational theme from the Bible. The International Baccalaureate Diploma Programme was introduced during his tenure. The school was the first in the Singapore education system to implement the programme. This was a significant step in the reform of Singaporean education system, which had been cited by critics as being too harsh and rigid in its regimen, not to mention its examination-centric approach towards achieving academic excellence. Ong maintained the school's reputation for strict discipline. He has said:
"We have corporal punishment for serious offences. If parents disagree, then they should not have put their child in this school".
The Anglo-Chinese School publicity material for the International Baccalaureate Diploma Programme additionally emphasises that IB students guilty of serious violations of academic dishonesty, if male, may be caned. In July 31st, 2016 Dr Ong Teck Chin was appointed principal of Singapore International School Of Bangkok Sixth Form and brought many new changes to the school administration, reflecting the styles of teaching in his previous school.
Controversy
On 4 October 2010, Ong announced his resignation as Principal/CEO of Anglo-Chinese School. It was implied that he stepped down for health reasons. However, his resignation came shortly after allegations of inappropriate behaviour towards a male teacher, Mark Richie Tan had been made about him to the ACS Board of Governors. An inquiry committee was formed, comprising members from both the Anglo-Chinese School Board of Governors and the Anglo-Chinese School Board of Management. Mark Richie Tan made statements to The New Paper stating that he filed the complaint because he "wanted justice to be served" and that there were "possibly a few people" involved in this matter. According to a report in The Straits Times, "Mr Tan told The Straits Times that he had e-mail, text messages and recordings to prove his claims of Dr Ong's inappropriate behaviour." The panel convened found that these allegations were reinforced by their findings: "Dr. Ong Teck Chin has conducted himself in an inappropriate manner and that his conduct has fallen short of the standards expected of a principal". The Board did not state the nature of the allegations. In a press statement on 22 November 2010, the ACS Board of Governors and the ACS Board of Management said that Ong deeply regretted his actions and had apologised. His last official day of work at ACS was 30 November 2010.
Health
In April 2008, Ong underwent major open heart surgery to correct coronary disease, after tests that indicated serious blockages of his coronary arteries.
Family
Ong is married to Goh Li Shien and they have three children – Marcus, Melissa and Matthias.
