The Short Answer
HITRUST certification typically takes 2 to 4 months for an e1 assessment, 4 to 8 months for i1, and 8 to 14 months for r2. As with cost, your assessment type is the primary driver of timeline, not company size. See our HITRUST certification guide for the difference between e1, i1, and r2, or our HITRUST certification cost breakdown for the budget side.
Timeline by Assessment Type
| Assessment type | Readiness | External validation | Total |
|---|---|---|---|
| e1 (Foundational) | 6 – 12 weeks | 3 – 4 weeks | 2 – 4 months |
| i1 (Implemented) | 12 – 26 weeks | 4 – 6 weeks | 4 – 8 months |
| r2 (Risk-based) | 28 – 50 weeks | 5 – 8 weeks | 8 – 14 months |
Readiness, gap analysis, control implementation, and evidence collection, is the larger share of the timeline at every tier. External validation adds a smaller, fairly consistent chunk on top regardless of assessment type.
Why Assessment Type Beats Company Size
e1's foundational control set doesn't expand dramatically with headcount, so a 30-person and a 300-person company both pursuing e1 face broadly similar timelines. The same 30-person company pursuing r2 instead faces a materially longer one, because r2 tests far more controls in far greater depth, independent of how many employees you have. Confirming which assessment type your customer actually requires, before committing to a schedule, is the single highest-leverage decision here.

Organizations that already hold SOC 2 or ISO 27001 typically move faster through readiness, since a meaningful share of the underlying controls and evidence overlap. This shortens the readiness phase, the largest line in the table above, more than it changes the external validation step.
Starting at e1 Saves Time Later Too
Evidence and control work validated during an e1 assessment carries forward if you later need to step up to i1 or r2. Starting at e1, confirming whether more is actually required, and stepping up only if needed is usually the lower-risk sequence, both for cost and for time, compared to committing to r2 upfront on the assumption it might eventually be needed.

Talk to an Avantcert ExpertFrequently asked questions about HITRUST certification timelines
Why does assessment type affect HITRUST timeline more than company size?
Because e1, i1, and r2 require fundamentally different depths of control testing and evidence collection, independent of headcount. A small company pursuing r2 faces a longer timeline than a much larger company pursuing e1, since r2's control depth, not company size, is what drives the schedule.
How long does an e1 assessment take from start to finish?
Typically 2 to 4 months, including readiness work against the foundational control set and the external assessor's validation. e1 is designed as a faster entry point, and most organizations without significant existing gaps complete it toward the shorter end of that range.
How long does an r2 assessment typically take?
8 to 14 months for a first-time r2, reflecting the depth of control testing required. Organizations that already hold SOC 2 or ISO 27001 typically move faster within that range, since a meaningful share of the underlying evidence and controls carry over.
Does starting with e1 and moving to i1 or r2 later save time on the second assessment?
Yes. Evidence and control work already validated during an e1 assessment carries forward, meaningfully shortening the readiness phase for a subsequent i1 or r2 cycle compared to starting that assessment type from a blank slate.
How much of the HITRUST timeline is the external assessor's schedule versus our own readiness work?
Readiness work, gap analysis, control implementation, evidence collection, is typically the larger share of the timeline. External assessor scheduling and the formal validation itself usually adds 3 to 6 weeks on top, depending on assessment type and the assessor's own capacity.
Can HITRUST certification be compressed for an urgent customer deadline?
Confirming the required assessment type first is the highest-leverage move; pursuing r2 when a customer only needs e1 adds months for no benefit. Beyond that, the control testing itself, particularly at i1 and r2, can't be meaningfully rushed without risking a failed validation.
