Depending on the performances at the preliminary examination, the selected students will be invited to take part in the final round of the COSL. Theory and practical workshops will be conducted at the IChemC premises at Rajagiriya for the finalists prior to the final examination.
National level winners will receive medals, certificates, monetary awards, and scholarships to study GIC programme in Chemistry.
In addition, students who obtain more than 50% marks from the preliminary exam will receive certificates of commendation.
The International Chemistry Olympiad (IChO) is a competition organized for secondary school students of all levels from all over the globe with the objective of promoting their creativity and cognitive skills in solving chemistry problems. The IChO competitions help to facilitate cordial relations between the youth of different nationalities and encourage networking.
IChO is just one out of the 12 International Science Olympiads held in the world. The rest cover other disciplines, such as Mathematics, Physics, Biology, etc. IChO headquarters is based in Bratislava, Slovakia of the former Eastern Bloc. This event began in 1968 with the participation from Czechoslovakia, Poland and Hungary. Other Eastern European countries joined the program subsequently. Western European nations entered to participate in this event in 1974 and the USA in 1984.
Some of the goals of the Chemistry Olympiad are as follows.
Currently, around 80 countries participate in this annual competition held for the world’s most talented secondary school level Chemistry students. In 2018 50th IChO competition was held in Bratislava, Slovakia and Prague, Czech Republic.
The Olympiad program is a multi-tiered competition and consists of the following format.
Only the teams chosen through a National Chemistry Olympiad competition are invited to take part in the IChO.
IChO steering committee has officially accepted the Institute of Chemistry Ceylon (IChemC) as the official organizer to conduct the National Chemistry Olympiad competition in Sri Lanka. In 2016, the Governing Council of the IChemC formed a committee comprising of academics attached to universities and institutes to organize and conduct the National Chemistry Olympiad Competition in Sri Lanka, which thus is named as Chemistry Olympiad Sri Lanka (COSL).
Sri Lanka participated in IChO as an observer in 2018 and will participate in IChO competition as a team in the year 2020.
