Judge Criteria
Each project is judged separately and will be judged on its own merit, in competition with other exhibits in its grade level. Judges will give consideration to the degree to which the judging criteria standards have been met. The judges will evaluate each exhibit using a point system giving up to the maximum value and their decision is final. Since we do not make any scores known to the public, judges are encouraged to leave constructive notes to help and motivate students.
Judging Process
The judges will score the exhibit based on the point breakdown as listed below and add up the points for an individual score. Individual scores of the judges are averaged together to form the project’s overall score. Judges are asked to be conscientious of the age group in which they are judging.
There are separate scoring sheets for each of the following divisions.
-
Kindergarten-2nd Grade Science Scoring Rubric
-
3rd-5th Grade Science Scoring Rubric
-
6th-12th Grade Science Scoring Rubric
