One entry, Peabody Teach science fair project rubric, is our own free tool. It is marked Ours and ranked against the same criteria as the others.

Quick answer

Peabody Teach's science fair project rubric is our number one: one rubric already split into K-2, 3-5 and 6-8. It prints or copies into Google Docs with no account. The ASA's judging guide comes second, with separate rubrics for grades K-4 and 5-8 that score each project out of 100. The list is for K-8 teachers and homeschool families running a class, school or home science fair.

1. Peabody Teach science fair project rubric

Peabody Teach

  • Ours
  • Best for one rubric in three grade bands
  • Free

One rubric page in three grade bands. K-2 uses three levels in plain words and no points; 3-5 and 6-8 use four levels with points, with the data row counting twice. Each band has five criteria, from the question and the fair test to the board and the talk to the judges. Each band prints with name, date and total lines, copies into Google Docs or Word as a table, prints as an "I can" checklist for students, or opens in the rubric maker to change any cell.

Free, no sign-in and no ads; Peabody is free through the end of 2026 (as of 2026-10-30).

Watch for It is one rubric for a classic experiment project; an engineering design project needs its own wording, which you would change in the maker.

2. ASA science fair judging guide and rubric

American Statistical Association

  • Best for separate K-4 and 5-8 rubrics
  • Free

The judging guide for the ASA's K-12 virtual science fair. It has separate rubrics for grades K-4, 5-8 and 9-12, scores each project out of 100 across five categories of up to 20 points, and describes high, average and needs-improvement work in each. It leans on data: collecting it, analyzing it and explaining what it shows.

A free PDF on the ASA site (as of 2026-10-30).

Watch for It was written for a video and essay entry, so some wording needs changing for a board at a school fair, and the PDF is not editable.

3. RubiStar Science Fair Experiment template

ALTEC at the University of Kansas

  • Best for building your own categories fast
  • Free

A rubric template you fill in from menus. Rows for this one include hypothesis, variables, procedure, data collection, diagrams, display and conclusion, on a four-level scale with headings you can rename. When you submit, you can print or download the rubric.

The page says there is no fee to register.

Watch for The page times out after 40 minutes without a submit, saving online needs an account, and a temporary rubric is kept for about a week.

4. Regina Regional Science Fair rubric and score sheet

Regina Regional Science Fair (Youth Science Canada)

  • Best for advice on running the judging
  • Free

A page for teachers running a school fair, with a judging criteria rubric and a judging score sheet to download. It explains how to use them: scores run from 10 to 100 and mainly put exhibits in order, there is no passing grade, and a short judges' meeting before the fair helps everyone score the same way.

Free downloads linked from the page (as of 2026-10-30).

Watch for It is a Canadian regional fair's rubric, close to the national fair's, and the page does not split it by grade; it notes young students will score lower.

5. Northern BC Regional Science Fair judging form, grades 4 to 6

Northern BC Regional Science Fair

  • Best for an upper elementary judging form
  • Free

A judging form written only for grades 4 to 6. Each category, such as presentation materials, the interview and scientific content, describes three levels, and the judge picks a level and then a score within its range. It reminds judges not to take marks off for technical trouble in the interview.

A free PDF (as of 2026-10-30).

Watch for The form is not returned to students and points to a separate comment form, so plan your own way to give feedback. It is a PDF, not editable.

6. Renfrew County fair scoring and feedback sheets

Renfrew County Regional Science and Technology Fair

  • Best for keeping scores and feedback apart
  • Free

Two sheets that do two jobs: a judging scoring sheet that stays with the fair, and a judging feedback sheet given to students after judging. The page says the forms can be used at other fairs, such as a school fair.

Free downloads linked from the page (as of 2026-10-30).

Watch for The page does not say which grades the sheets are written for, so read them before using with younger students.

7. Regeneron ISEF judging criteria

Society for Science

  • Best for 7th and 8th graders aiming at regionals
  • Free

The criteria used at the international fair, with separate versions for science and engineering projects. Each totals 100 points: the research question or problem 10, design and methodology 15, execution 20, creativity and potential impact 20, and presentation 35 (poster 10, interview 25). Many regional fairs build their own sheets from it.

A free page; no cost is mentioned (as of 2026-10-30).

Watch for It is written for high school finalists and their judges, so it asks far more than a K-5 project can show. It is a web page, not a printable sheet.

8. Montana Science Fair judging criteria and score sheet

Montana Science Fair, University of Montana

  • Best for a team project score sheet
  • Free

A state fair's judging page that lists its criteria, creative ability, scientific thought or engineering goals, thoroughness, skill and clarity, with points for each and a separate set for team projects that adds teamwork. It links a printable judging score sheet.

Free page and printable sheet (as of 2026-10-30).

Watch for The page gives one set of criteria with no split by grade, and its point values differ between its volunteer and registration pages, so check the sheet you print.

How we chose

We weighed these, most important first. The order is our judgement against them, not a score or a vote, and a different teacher could reasonably order it differently. Our own tool sits where those criteria put it; we built it after studying the others, so read its entry with that in mind.

  1. Fits the grade. Whether the rubric or sheet is written for younger students, or comes in separate versions by grade, instead of one sheet built for high school.
  2. Ready for judges. Whether a judge can pick it up on fair day: clear categories, points or levels, and room to write a score.
  3. Free to print. Whether the page offers the sheet at no cost, and whether you must log in or make an account to download it.
  4. Easy to change. Whether you can edit the wording or categories for your own fair, or only print it as it is.
  5. Feedback for students. Whether the source says how scores or comments go back to students, since a score sheet alone teaches little.

We took no money, free products or affiliate commissions for any place on this list, and no link here carries a tracking code. Every fact was read on the maker’s own page on October 30, 2026; prices carry that date because they change. See how we choose and the ad-free promise.

Questions

Should students see the judges' rubric before the fair?
Yes, when it is a class project. Sending the rubric home when the project is assigned shows students and families what judges look for. Some regional fairs keep the score sheet and give students a separate feedback sheet, which works well at a school fair too.
How is a K-2 science fair rubric different?
Younger students are judged on whether they asked a question they could test, did the test, said what they found and can talk about it. Named variables, repeated trials and sources of error belong in the upper grades. Peabody's rubric uses three plain-word levels with no points for K-2.
How do I get judges to score the same way?
Meet for ten minutes before judging starts and score one sample project together. The Regina Regional Science Fair suggests a short judging session like this so everyone holds the same standard.
Do I need separate rubrics for science and engineering projects?
It helps. An engineering project tests a design against a need instead of a hypothesis. The international fair uses two versions of its criteria, one for science and one for engineering.
