The NCI Preferred Standard CDEs represent those that have been through the NCI's Content Owners Governance and have been determined to meet all the necessary criteria for standardization based on NCI Best Practices. When looking for NCI recommended CDEs, this is the place to start. The attached files are for downloading, a web browser view for comparing or viewing details of these CDEs is available by visiting the CDE Browser and clicking on the "NCI Standards" Context, or by performing an Advanced Search, selecting Registration Status = "Preferred Standard".
Other reusable CDEs can be found by searching using the CDE Browser if you do not find CDEs in the Preferred Standard set that meet your needs. The community standard CDEs have Registration Status = "Standard", and sort to the top of the search results by default, right after "Preferred Standard" For more information about Content development at NCI, see caDSR Content.
