This bank pulls together questions from the Biological Sciences Curriculum Study (BSCS) and other sources. Most were written for Project 2061, a long-term research and development initiative sponsored by the American Association for the Advancement of Science and the National Science Foundation.

The BSCS assessment questions are referred to on the host website as the “Original Project”. They are re-published in Problem-Attic along with NGSS questions from four other sources: ASPECt (Assessing Students’ Progress on the Energy Concept), The Evolution Project, Toward High School Biology (THSB), and Matter and Energy for Growth and Activity (MEGA).

For more details about the questions, alignment with NGSS, and ideas for classroom use, please visit bscs.org. The organization which hosts the website is now named BSCS Science Learning.
