BIO Support for Research Experiences for K-12 Teachers


The NSF Directorate for Biological Sciences (BIO) believes that encouraging active participation of teachers in on-going NSF projects is an excellent way to strengthen the science expertise of our nation's teachers, including those at urban or rural schools and those at school districts with limited resources. Research experiences at the emerging frontiers of science can enhance the professional development of K-12 science educators in order to bring new knowledge into the classroom, thus impacting a broad range of students and supporting the next generation biological sciences workforce.

While the Research Experiences for Teachers Sites in Biological Sciences (BIORETS) has been sunsetted, BIO continues to support research experiences for K-12 teachers through supplemental funding opportunities. For more information on the availability of and how to apply for supplements for existing NSF grants, please read the Dear Colleague Letter Research Experience for Teachers (RET): Funding Opportunity in the Biological Sciences (NSF 23-146)
