Welcome to Loudoun County Public Schools
    Due to the COVID-19 outreak, we have had to cancel the 2020 LCPS Regional Science & Engineering Fair (RSEF). We were hopeful that we could transform the RSEF into a virtual fair, but the closing of schools, rapidly changing public health situation and the need to prepare for continuity of education, has made it impossible to conduct the RSEF and meet the requirements for participation as an affiliated fair for the Regeneron International Science & Engineering Fair. We will continue to explore ways for our RSEF participants to present their research to the scientific community, but we do not have any specific plans or details to share at this time.
    Thanks to our sponsors, donors, judges and community members who make this event possible each year and who acknoledge and honor the efforts of the 366 RSEF student researchers who were selected to participate in 2020.

    2021 Regional Science & Engineering Fair (RSEF)  


    The purpose of our fair is 

    • to stimulate student interest in science, technology, engineering, and mathematics (STEM)

    • to encourage students to engage in research in STEM fields.

    • to provide students opportunities to present research to STEM professionals and the community, and

    • to give public recognition to students for their work.
