Become a Fair Judge

Make an Impact: Volunteer as a Science & Engineering Fair Judge

Every year, thousands of students across Massachusetts put their creativity and problem-solving skills to the test through science fairs at the school, district, and regional levels. The best of these projects advance to the iconic Massachusetts Science & Engineering Fair, an annual celebration of student ingenuity that has been celebrating young minds since 1949. This event is a showcase of the power of independent student-led stem research.

We invite STEM professionals and academics to volunteer as judges for this exciting event. Judging is a chance to make a meaningful impact on students, offering them encouragement and inspiration as they share their research. For many students, presenting their projects to a STEM professional is a milestone experience that builds confidence and expands their view of what’s possible.

As a judge, you’ll also find value in this experience!

Reignite your passion for STEM,
Reconnect with your own science fair memories,
Engage with the community in a rewarding way,
And support the next generation of thinkers, innovators, and leaders

Join us in shaping the future of STEM by volunteering as a judge. Your involvement can make a lasting difference in the lives of students across the Commonwealth

Regional Map

You are eligible to judge in any regional fair regardless of where you live or work.

Criteria and Expectations

Requirements vary for Regional, Middle School and High School Fairs. However, in all instance judges must have experience in a STEM field: Biology, Chemistry, Biochemistry, Behavioral Science, Earth & Environmental Science, Astronomy & Space Science, Physics, Engineering, Mathematics & Modeling, Computer Science & Technology.

High School Regional Fairs Judges must hold a bachelor’s degree or higher in a STEM field or have 4+ years working experience in their selected STEM field. For the regional fairs only, graduating seniors majoring in Computer Science, Behavioral and Social Sciences, or Environmental Sciences are eligible.

High School State Fairs Judges must hold an advanced degree (masters or higher) or a bachelor’s degree and 4+ years experience.

Middle School Regional and State Fairs Judges must hold a STEM degree* and/or working experience in that field. *Current STEM majors- juniors and seniors- are eligible.

Due to a conflict of interest:

Individuals should not judge during a fair season when a family member is presenting a project.
Teachers and current mentors should not judge if they have students participating at the Fair.

Judges should let the Fair judging coordinator know if there are other potential conflict of interest based on a non-family relationship or previous mentorship.

Frequently asked questions

Do you provide training for fair judges?

Yes! Judges are required to attend a short virtual training session in advance of the Fair.

Consult the Judge Info tab on the zFairs pages for training dates and expectations.

https://mahs.zfairs.com for High School training information.

https://mams.zfairs.com for Middle School training information.

During the training you will be fully briefed on the judging rubric (with point allocations) that will guide your assessment. We will explain how scoring is adjusted to weigh the core process, student understanding over sophistication, the importance of independent work, and creative use of materials.

During this session, you will also receive details about when to arrive, where to go, and other important information.

Judges commit to providing a rigorous, yet encouraging, interview process for students.
What is the schedule for judge orientation sessions?

Once you have registered on the middle school or high school zFairs site for judging at a fair, you will be expected to sign up for a required orientation session in advance of the fair.

Go to https://mahs.zfairs.com for High School training information.

Go to https://mams.zfairs.com for Middle School training information.
How many students will I talk with?

You will typically review 3-6 projects which includes a student presentation and Q&A session. Each project is judged by multiple judges separately.
What is the time commitment?

The advance training is approximately 1 hour on zoom. On the day of the Fair you can expect to give 3-5 hours of your time.
What do I do if I sign up and cannot make it on the day?

Please let us know as soon as possible if you are unable to attend a fair you signed up for. When judges are absent, students may not have enough reviewers for their projects, requiring MSEF staff to quickly reassign coverage. This can create additional challenges and place extra responsibility on other judges.

State Fair judges should email judginginfo@scifair.com

Regional judges should contact the email of the regional coordinator.
Can I talk to someone directly?

Yes! Email judginginfo@scifair.com with questions.

We can help you connect with the regional fair contacts as needed.

What our students say

“The conversations I had with the judges were the best part of the science fair. Being able to converse in an intelligent way with someone with that background and have them understand what I was talking about made me feel so capable and smart.”

– High School Student

What our judges say

“I enjoyed talking to the students, listening to their project and witnessing their enthusiasm pouring out.”
