In the first stage of its work, Project 2061 commissioned panels of scientists, mathematicians, and technologists to identify the knowledge and skills students should have in five subject areas. These panel reports--Biological and Health Sciences, Mathematics, Physical & Information Sciences and Engineering, Social and Behavioral Sciences, and Technology were integrated into the Project's 1989 report, Science for All Americans (SFAA), which outlines what all students should know and be able to do in science, mathematics, and technology after 13 years of schooling.
