Rules Clarifications

Clarifications & FAQs open October 1 and close May 1. Official Rules Clarifications are made to clarify or correct the rules printed in the Science Olympiad Rules Manuals. FAQs are replies to commonly asked questions. If a FAQ reply changes the meaning or corrects a rule it will be posted as a Clarification. The Official Rules Clarifications and FAQs apply to all states and all tournaments and originate at the National level (please check your Regional or State Website for special updates pertaining to your regional or state events). Click here to view Event FAQs or to Submit a Question. The official event rules can only found in the Science Olympiad Rules Manual that is sent to each Registered Member (to participate in any Science Olympiad Tournament a team MUST be a Member). Extra Rules Manuals can be purchased on the Science Olympiad Store or by purchasing a Science Olympiad Mobile Rules App in the Google Play or iTunes Stores.
