Classification, categories and types

Classification, categories and types

Once the project idea has been identified, the classification, category, and type of project must be determined.


Here are the Science Fairs Classes, depending of your school level.


  • Juvenile 1 : Elementary level, cycle 1
  • Juvenile 2 : Elementary level, cycle 2
  • Juvenile 3 : Elementary level, cycle 3


  • Junior : secondary 1
  • Intermediate : secondary 2 and 3
  • Senior :  secondary 4 and 5
  • Collegial 1 : 1st and 2nd year of a pre-university program
  • Collegial 2 :  1st to 3rd year of a technical program, or 3rd year of a Double Dec programs

Note: Collegiate classes 1 & 2 are grouped into one class for judging and prices.

Note that Collegial 2 class – Technical Students and 3rd Year of the Double DEC are not eligible to participate in the Canada-Wide Science Fair. However, they are eligible for the International Science Fair.


All Science Fair projects are presented according to a classification defined by the Science Fair program.

For each classification, a non-exhaustive list was drawn to guide you in identifying the classification best representing your project’s field of expertise.

Project type

The type of Science Fair project refers to how you will deal with your subject. There are three approaches:


To experiment is to discover new ways of doing things or to improve those that already exist. It’s trying to prove an idea or help to understand the purpose of a reality.



To conceive is to realize a technique, a model, a method, a device, a product or a software; or improve the capabilities and functions of a device, software or product.


To vulgarize is first to study a subject in depth using several sources of information. It is then to make the technical and scientific knowledge accessible to the general public.


In the “Tools” sections, you will find all the information you need to clearly distinguish the project types.
