stage (''Olimpiade Sains Provinsi'')
Regardless of the pre-provincial stage selections, a single province are allowed to represent themselves by up to three times the number of province's regencies in terms of student count, with a minimum limit of a single student per regency. The aforementioned students sit in a single exam which is held simultaneously across the country.
Individual schools are limited to sending 3 students to this exam. # National stage
A minimum of 1 student per province and generally less than 100 students nationally per subject come together and sit exams, generally one theoretical and one experimental, and winners are selected.
Individual awards include ''Absolute Winner'' (First place), ''Best Theory'' and ''Best Experiment'' (highest scores in theoretical and experimental exams respectively), along with gold (ranks 1–5), silver (ranks 6-15), and bronze (ranks 16–30) medals. In 2016, over 320,000 students participated in the ''Olimpiade Sains Kabupaten'' across Indonesia, with 1,579 eventually making it into the national phase. In comparison, 420 medals were given out in 2017.
