HITRUST enforces strict evidence requirements to maintain credibility of assessment results. ForPolicy and Procedurematurity levels, if a score above 25% is claimed, the organization must link appropriate evidence (e.g., documented policies, standard operating procedures). ForImplementation, Measured, and Managed, evidence must be provided whenever a score greater than 0% is claimed. This ensures that claims are supported by objective artifacts rather than assertions. Evidence can include policy documents, monitoring reports, logs, meeting minutes, or audit records. HITRUST QA verifies that evidence is linked to requirement statements at each maturity level. Without linked evidence, scores may be reduced or reverted during QA.
This policy ensures transparency, accountability, and prevents overstatement of control effectiveness.

HITRUST CSF'srisk-based levelswere adapted fromNIST SP 800-53, which organizes controls into baseline categories based on impact levels:low, moderate, and high. Similarly, HITRUST assigns requirement statements across multiple implementation levels (Level 1, Level 2, and Level 3) depending on organizational, technical, and regulatory risk factors. This approach ensures scalability, so smaller organizations or lower-risk environments face fewer requirements, while larger, high-risk entities face more.
HITRUST harmonized this concept with mappings to other frameworks (ISO, HIPAA, PCI-DSS), but the structure of escalating control rigor by risk exposure is directly derived from NIST's model. This alignment reinforces HITRUST's credibility as a risk-based framework consistent with widely accepted standards.

In ani1 assessment, remediated controls must demonstratesustained effectivenessbefore being retested.
HITRUST requires a minimum of90 daysbetween remediation and reconsideration of the Implemented maturity level. This waiting period ensures that corrective actions are not only implemented but also consistently applied over time. For example, if patch management processes were deficient and then corrected, HITRUST wants to see proof that the new process has been followed successfully across multiple cycles. Immediate or short-term remediation is insufficient, as it may not show durability. This rule reinforces HITRUST's focus onoperational maturityand real-world assurance, preventing organizations from implementing "point-in-time fixes" just to pass assessments.

HITRUST requires that each of the19 domainsachieve a minimum score of71for an organization to qualify for r2 certification. This threshold ensures that entities maintain a consistent level of maturity across all control areas, rather than excelling in some while neglecting others. The 71 threshold is calculated from the weighted average of requirement statements within a domain, factoring in Policy, Procedure, and Implementation maturity scores (with Measured and Managed as applicable). If any domain falls below 71, the assessment may still produce a validated report, but it will not result in certification. This strict requirement highlights HITRUST's emphasis onbalanced coverageacross all areas of security and privacy.

TheMeasured maturity levelevaluates whether organizations actively monitor the effectiveness of controls.
HITRUST definesseven criteriafor Measured, including metrics, data collection, analysis, reporting, and corrective action tracking. If these seven criteria are fully met, scoring can begin atTier 4 strength, reflecting a mature measurement process. In the example, system administrators are responsible for measuring firewall configuration security, and if they meet all seven criteria (such as reviewing firewall rules, analyzing logs, reporting deviations, and initiating remediation), the Measured compliance level can start at Tier 4. The assessor may then adjust scoring based on coverage and frequency, but the baseline is Tier 4 once all criteria are satisfied. This ensures consistent evaluation of advanced maturity levels across controls.
