The scoring of Requirement Statements is used to calculate the overall Domain score.

In HITRUST, scoring follows ahierarchical roll-up process. At the lowest level,Requirement Statementsare scored across the five maturity levels: Policy, Procedure, Implemented, Measured, and Managed. These individual requirement scores are then aggregated to produce theControl Reference score. Control Reference scores are averaged to determine theDomain score, and finally, domain scores are used to determine whether certification thresholds are met. Each level of scoring influences the next, meaning deficiencies at the Requirement Statement level impact the higher-level domain performance. This structure ensures that assessments provide a balanced and transparent picture of organizational control effectiveness. No single requirement is hidden; its performance is reflected in the domain-level scoring. Since r2 certifications require each of the 19 domains to score at least 71, accuracy in Requirement Statement scoring is critical.
