He competed in his first Junior World Championships in 2006.
At his first Junior World Championships in 2006 in Presque Isle, Maine, United States, Bø claimed the gold medal in the individual discipline, and the silver medal in the pursuit discipline. A year later in Martell-Val Martello, Italy, Bø again claimed the silver medal in the pursuit discipline, and was part of the Norwegian relay team that won the silver medal. The 2009 Junior World Championships in Canmore, Canada began in disappointment: Bø finished as number 23 in the individual discipline with a total of five shooting errors. However, Bø would eventually claim the bronze medal in both the pursuit and sprint disciplines. During the 2009 European Championships in Ufa, Russia, Bø was the most successful biathlete, and claimed the gold medal in all four races he entered (individual, sprint, pursuit and relay). At the World Cup finals in Khanty Mansiysk, Russia, Bø made his debut in the Biathlon World Cup on 26 March 2009, finishing 61st.
Bø became a regular fixture in the Norwegian team in the 2010–11 season. He started the season with a fourth place in the individual discipline in Östersund, Sweden, followed by a fifth and fourth place in the sprint and pursuit disciplines, respectively. On 5 January 2007, Bø won his first World Cup event, the sprint race in Hochfilzen, Austria, beating runner-up Serguei Sednev by 27.5 seconds. One day later, he won his second World Cup victory in the pursuit discipline. On 12 December, he was part of the winning Norwegian relay team. After his highly successful races in Hochfilzen, Bø took the yellow bib of the Overall World Cup leader. In the races in Pokljuka, Bø finished 12th in the individual discipline and second in the sprint. In Oberhof, Bø claimed his third and fourth World Cup victories (mass start and sprint). At the World Cup stops in February in the United States, Bø continued his good form; his worst result was a sixth place. In Presque Isle, Maine, he came in fourth in the sprint discipline. One week later in Fort Kent, Maine, Bø finished all three races in third place (sprint, pursuit and mass start).
