Intel ISEF categories and subcategories

The categories listed below are those that will be used at the Intel ISEF 2017. 

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.

Category Selection Advisement:

Many projects could easily fit into more than one Intel ISEF category. We highly recommend that you review the entire listing of the new categories before choosing 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:

  1. 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?)
  2. 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? Is it inserting the proper gene or the method of computer mapping to demonstrate the results?)

Databases (DAT): Studies that create or analyze data organization for ease of access, management and update. 

Human/Machine Interface (HMC): Software application that presents information to a user about the state of a process and to accept and implement the operator’s control instructions.

Languages and Operating Systems (LNG)Studies that involve the development or analysis of artificial languages used to write instructions that can be translated into machine language and then executed by a computer or system software responsible for the direct control and management of hardware and basic system operations of a computer or mobile device.

Mobile Apps (APP): A study involving a software application developed specifically for use on small, wireless computing devices.  These studies may include front-end development techniques, such as user interface design and cross-platform support, and/or back-end development techniques, such as data services and business logic.

Online Learning (LRN): Studies that focus on utilizing electronic technologies to access educational curriculum outside of a traditional means.  Studies explore the design of learning activities and programs with online technologies, as well as the effective use of e-learning systems.

Translational Medical Science (Code: TMED)

Projects that aim to improve human health and longevity by translating novel discoveries in the biomedical sciences into effective activities and tools for clinical and public health use. Bi-directional in concept, projects can be those developed through basic research moving toward clinical testing (bench-to-bedside) or projects that provide feedback about the applications of new treatments and how they can be improved (beside-to-bench).


Disease Detection and Diagnosis
Disease Prevention
Disease Treatment and Therapies
Drug Identification and Testing
Pre-Clinical Studies

Disease Detection and Diagnosis (DIS): Studies in this category encompass a variety of novel assay methods to promote the identification, detection and determination of disorders and disease. They may involve studies at the system, organ, or cellular levels.

Disease Prevention (PRE): The study of health promotion and disease prevention activities and research to improve public health. These  studies might involve research to protect individuals from actual or potential health threats and their harmful consequences, or they may address novel approaches to aid in compliance for avoiding known health risks (e.g., smoking, drug use, obesity).

Disease Treatment and Therapies (TRE): The use of pharmaceuticals and other therapies, including natural and holistic remedies, intended to improve symptoms and treat or cure disorders or disease.

Drug Identification and Testing (DRU): These studies would be conducted to identify potential drugs or extracts that could be used to treat or cure disorders or disease. Studies in this category would involve initial testing of the compounds against an intended target. This category could also include testing a range of different compounds or extracts to determine relative potency and efficacy.

Pre-Clinical Studies (PCS)These studies of potential drugs or therapies would include testing the intervention in platforms such as cultured cells or animal models of disease. The investigations could be directed toward determining factors such as potential drug permeability, efficacy and/or toxicity. These studies could also investigate the best route of drug administration.
