Science Fair Judges & Volunteers

Inspire and connect

with the next generation of Minnesota scientists and engineers!

The Minnesota State Science & Engineering Fair is an annual event where hundreds of middle and high school students from across Minnesota present the results of their original research to STEM professionals, gaining valuable feedback.

2025 General Awards Judge Registration is NOW OPEN, register here and click “create account” in the top left.

  • Feedback from judges is extremely important for our student participants.

    Here’s some feedback we received from the 2022 event from judges:

    “I really enjoy talking with young scientists and working with students to help them improve their critical thinking skills and encourage their curiosity.”

    “I am glad to be able to judge these projects. The overall caliber of scientific work is excellent, especially at a high school level, and has good novelty.”

    “I enjoy supporting young interested scientists. Every year I am blown away by what these students can accomplish. Whether it's Middle School or High School projects, there are always projects that strike me as way beyond the expectations that we would have for students their age.”

  • Judges must have an interest and experience in social science or a science, technology, engineering or math (STEM) field. We welcome judges from most levels of education and experience.

    High school project judges must:
    - have at least a Bachelor’s degree OR
    - have at least four years of experience in a social science or STEM field

    Middle school project judges must:
    - have either of the qualifications listed above OR
    - have at least two years of experience in a social science or STEM field OR
    - be a current student in a social science or STEM field as an undergraduate, in a trade or in a two-year college

    Judges who are parents, relatives, and teachers of students competing must disclose their connections to participants by answering a particular question in the registration process to avoid conflicts of interest in assignments.

  • No matter the topic, you are evaluating

    • whether or not you think the project has a clear purpose or problem that’s testable or addresses a certain need,

    • if the research plan was well-designed and variables appropriate,

    • if data were collected systematically or the prototype was tested in multiple conditions,

    • if the student showed creativity, and

    • how the poster and conversation were.

    We have a rubric for you to fill out.
