ThinkQuest is an international student competition, sponsored by the Oracle Education Foundation. Students work in teams to build creative and educational websites that explore globally relevant subjects. Diverse teams made up of members from more than one school, community, or country are encouraged. Competitions are open to students and teachers from anywhere in the world. Teams must have 3 to 6 students who are between the ages of 9 and 19, and one adult Coach who is a school employee. Homeschooled students may participate so long as they are part of a team that is associated with an accredited public, private, or parochial school (i.e., Primary Coach is an employee of an accredited public, private or parochial school and other team members are affiliated with an accredited school). Homeschooled students might consider forming a team with students from another country. Being a member of a multi-country team presents a great opportunity for all students to learn about other cultures and to learn valuable collaboration skills. The completed websites are published in the ThinkQuest Library, a rich learning resource used by millions.
