The categories listed below are those used at the Intel ISEF. Local, regional, state and country fairs may or may not choose to use these new categories, dependent on the needs of their area. Please check with your affiliated fair(s) for the appropriate category listings at that level of competition.
Use the list of category links below to go directly to the one you are interested in or browse through the entire list of available categories.
Category Selection Advisement:
Many projects could easily fit into more than one Intel ISEF category. It is your decision to choose the category that most accurately describes your project.
You don’t need to compete in the same category as in your regional or state competition. Furthermore, most regional and state competitions do not use sub-categories. We attempt to match judges to projects first at the sub-category level and then at the category level as best as possible, so the selection of a sub-category should also be given consideration. “Other” as a sub-category most often will match the project with a wide range of judges across the category.
Ask yourself the following questions to help in the selection of a category:
