Since 1967, the International Physics Olympiad (IPhO) competition has been held in different countries. The Asian Physics Olympiad (APhO) competition commenced in the year 2000. Participation in the Olympiads gives opportunities to young, bright students from all over the world to share experiences and face challenges in solving Physics problems.

Since 2005, the Institute of Physics has conducted an island-wide competition called “Sri Lankan Physics Olympiad” to recognize and promote Physics among A/L students. The best students will receive medals and certificates from the Institute of Physics, Sri Lanka. Based on the marks obtained from this local competition, the best students will be selected to participate in the APhO and IPhO, respectively. Under IPSL sponsorship, Sri Lankan students participated in IPhO 2005 in Spain, IPhO 2006 in Singapore, APhO 2007 in China, APhO 2008 in Mongolia, IPhO 2008 in Vietnam, APhO 2009 in Thailand, IPhO 2010 in Croatia, APhO 2011 in Israel, and IPhO 2011 in Thailand.
