Each project must be entered into one of the 17 science, math, and engineering categories below. Many projects can easily fit into more than one Intel ISEF category, therefore, it is your decision to choose the category that most accurately describes your project.
Ask yourself the following questions to help in the selection of a category:
- Who will be the most qualified to judge my project? What area of expertise is the most important for the judge to have? (For example, a medical background or an engineering background?)
- What is the emphasis of my project? What characteristic of my project is the most innovative, unique or important? (For example, is it the application in medicine or the engineering of the machine?)
Please note: Fair officials reserve the right to combine similar categories into larger judging groups to streamline the judging process. Please visit our archives to see how we have grouped together categories in the past.
