Judges evaluate the quality of work done in planning and carrying out a project in pure applied science as well as how well the student understands the project and the subject area. The display itself is a minor portion of the project. Higher marks are generally given to the projects laboratory, field or theoretical investigation or construction that demonstrates a creative approach or original thought. Part of what needs to be assessed is where the participant obtained the idea for the project and how much outside help was received.

The three types of projects represented in the Regional Science Fair are as follows:

An experiment:
A project of this type would be an investigation undertaken to test a specific hypothesis using experimental methods. Experimental variables, if identified, are controlled to some extent.

A study:
This type of project is a collection and analysis of data to reveal evidence of a fact or a situation of scientific interest. This could include a study of cause and effect relationships involving social, political, or economic considerations; in depth studies and theoretical investigations. Identified variables are not feasible to control but meaningful correlations are encouraged.

An innovation:
A project of this type would be one involving the development and evaluation of innovative devices, models, or techniques or approaches in fields such as technology, engineering, or computers (both hardware and software).
