UK Biology Competitions(UKBC) registered as a charity in England and Wales number 1191037 in 2020, after operating as independent group for 25 years with extensive experience in writing biology exams for all ages of secondary school students. Every year, they deliver 3 high quality exams for over 60,000 students. UKBC work closely with the Royal Society of Biology and University of Warwick to bring these exams to as many students as possible.

The British Biology Olympiad was created in 1995, stimulating students with an interest in Biology to expand and extend their talents. It is one of the largest science competitions in the UK with more than 7,200 high school students participating in 2016. Each year an outstanding team of high school students is then selected to represent the UK in the International Biology Olympiad (IBO). It enables students to demonstrate their knowledge and to be suitably rewarded and publicly recognized through the award of medals, certificates and other prizes. It is hoped that by competing in this Olympiad, students who are already interested in this valuable, wide-ranging and rewarding subject will be encouraged to continue their studies beyond A-level.

ASDAN China (ASDAN Academy) introduced this competition to China from 2016. Outstanding Chinese students will have the opportunity to compete with British students for the award of medals. They will also be given the chance to attend top science programs in the future. Representatives from 243 international and key middle schools have participated in this competition in 2020.

(For judging the global awards, British competitors will be ranked first by their overall scores in the top 5%, 15%, 30%, 45%, 60% creating boundaries for the gold, silver and bronze awards. Competitors from other countries are not ranked together with their British competitors, but are compared by boundary. Chinese competitors with good results will therefore have an increased chance of receiving an award.)
