Tadqiqotchining c-score koʻrsatkichini belgilovchi parametrlar quyidagilardir:
* olingan iqtiboslarning umumiy soni;
* olingan iqtiboslar uchun Xirsh indeksi;
* olingan iqtiboslar uchun Shrayber hammualliflik hisobga olingan tuzatilgan Hm indeksi;
* olim yagona muallif boʻlgan maqolalarga berilgan iqtiboslarning umumiy soni;
* olim yagona yoki birinchi muallif boʻlgan maqolalarga berilgan iqtiboslarning umumiy soni;
* olim yagona, birinchi yoki oxirgi muallif boʻlgan maqolalarga berilgan iqtiboslarning umumiy soni.
