Quia (pronounced "KEY-ah" much like "Maria") is short for "Quintessential Instructional Archive." It is a website that enables any educator to create and share quizzes and other resources. It also lets teachers track the results and the time that students spend using the materials.

Quia offers teachers templates for creating 16 online activities including flashcards, word searches, memory games and other quiz and challenge formats. Ten different quiz formats are available (such as multiple choice, true/false, short answer, essay and ordering. 

More than 3 million activities in 100 languages have already been created and shared on Quia.

Students can use Quia activities in either a "logged in" or non-logged in state. When students have logged into the account, teachers can track students' practice time and quiz results.

Quia supports a multitude of data formats including: images, audio files, as well as doc files. Quia runs in a browser and so operates on most computers. The company recommends using monitors that can display a 800x600 pixel image (or better, 1024x768 resolution with 32-bit color). Audio files require that computers can play voice-quality sound (either on speakers or via headphones). Quia also requires a minimum 56Kbps or faster Internet connection and a web browser: Internet Explorer 6 through 9, Firefox, Chrome, or Safari 3 through 5. (Quia does not support the use of Asian characters on Macintosh platforms.) Some Quia activities make use of Flash or Java applets. (Here are the detailed system requirements.)

The company offers a 30-day free trial. Annual subscriptions for educators (including home educators) cost $49; for groups of 10 teachers, the price drops to $39 apiece. (More pricing here.)
