The Central Java contingent is a contingent who often holds the overall title in the National Science Olympiad (OSN) competition with the DKI Jakarta contingent. From 17 OSN implementation since 2002, the Central Java contingent held the title 10 times, and the rest were taken by DKI Jakarta. Many factors influence a team to become champions, namely students as active actors, mentors, and also provincial education offices. This article materialized from the authors experience to become the Central Java Province OSN advisory team for elementary and junior high school for mathematics. Hopefully, this experience can be a reference for other provinces in guiding their best students so that it will be more competitive in the National Science Olympiad event.
