The Informatics Olympiads are competitive programming contests for secondary school students. They require basic skills in algorithms and data structures.
In India we have the Indian Computing Olympiads which leads to the International Informatics Olympiad(IOI). The Indian Computing Olympiads are managed by IARCS (Indian Association for Research in Computing Science).
