There are two categories of participant: existing CKD models with a fixed number of bands and spectral intervals, and CKD tools, which generate new CKD models with some control over the accuracy, efficiency (i.e. total number of spectral intervals) and range of applicability. The main purpose of CKDMIP is to evaluate an improve the way that CKD tools generate CKD models.
