Variable Standards Finder

Answer these questions to discover standards for your variables. This quiz will recommend Common Data Elements (CDEs) and/or controlled vocabularies based on your answers. CDEs are standardized variable structures ready for use. Controlled vocabularies can be used when creating custom variables, usually in the variable label/description or its choice list.

These resources are provided for consideration and are not necessarily a reflection of award requirements. If you have a specific study in mind, this quiz will indicate possible requirements, but quiz results are not determinative. Always refer to the terms and conditions of the Notice of Award (NOA), the Program Officer, and the Data Coordinating Center (if applicable) to identify variable standards requirements.
