Welcome to the AAAS Project 2061 Science Assessment Website
Want to learn more about the AAAS Project 2061 approach to science assessment?
Join us for a three-day professional development workshop, May 15–17, in Washington, DC. Full details and registration information here.
The assessment items on this website are the result of more than a decade of research and development by Project 2061, a long-term science education reform initiative of the American Association for the Advancement of Science.
Here you will find free access to more than 600 items. The items:
- Are appropriate for middle and early high school students.
- Test student understanding in the earth, life, physical sciences, and the nature of science.
- Test for common misconceptions as well as correct ideas.
This website also includes:
- Data on how well U.S. students are doing in science and where they are having difficulties, broken out by gender, English language learner status, and whether the students are in middle school or high school.
- “My Item Bank,” a feature that allows you to select, save, and print items and answer keys (requires site registration).
- A feature that allows you to create and take tests online using items from the item collection (requires site registration).
Intended primarily for teachers, these assessment items and resources will also be useful to education researchers, test developers, and anyone who is interested in the performance of middle and high school students in science.
View key ideas, items, and misconceptions by browsing the topics.
