There are many features of the HITRUST assessment and reporting approach such as extensive assessment guidance, the training and vetting of qualified assessors, the implementation maturity model used to evaluate every HITRUST CSF control requirement, and the centralized quality assurance review of every assessment for which HITRUST issues a report that distinguishes HITRUST assessments from other commercially available assessment available today in terms of the accuracy and precision of the results. The model is also a key component of QQRRA.
