Judge reviewing a project

Encourage young researchers and innovators by being a judge at MSSF! Our judges come from a variety of backgrounds and each one brings their own unique experiences and perspectives to the event. We truly could not do this without you!


The Maine State Science Fair is recruiting judges across all project categories. 

  • Animal Sciences
  • Behavioral and Social Sciences
  • Biological Sciences and Engineering
  • Biomedical and Health Sciences
  • Chemistry and Materials
  • Computer Science
  • Energy and Transportation
  • Earth and Environmental Sciences and Engineering
  • Engineering Mechanics
  • Mathematical Sciences
  • Microbiology
  • Physics and Astronomy
  • Plant Science
MSSF Judges must have advanced training or practical experience in science, technology, engineering, mathematics, computer science, or an associated field. Judges must engage in constructive analysis and discussion of a research or engineering project with a high school student and determine the relative strengths and weaknesses of a given project according to a standard rubric. Judges must be highly collaborative and able to work in small groups.  In addition to evaluating projects, judges also serve as informal mentors, providing useful feedback, advice, and encouragement to all students.

If you have questions, please email sciencefair@jax.org


The application period for judging at the 2022 MSSF is now closed. Contact sciencefair@jax.org if you have been asked to apply and need the link.

Judges will have the option of attending our in-person event at Colby College in Waterville or judging virtually via RocketJudge.

All judges are invited to our online orientation session on Friday, March 18, 2022 from 11:30am to noon.

Judging will take place on Saturday, March 26, 2022 from 8am to 1pm.


Judges assess student work using the International Science & Engineering Fair criteria. There are two rubrics for judging at MSSF: one for scientific research projects and the other for engineering design projects.
