The Digital Technology Assessment Criteria (DTAC) is the NHS’s standard for evaluating whether digital health technologies (DHTs) meet core requirements for clinical safety, data protection, technical assurance, interoperability, and usability.
It provides a clear benchmark for what “good” looks like, ensuring that the digital tools used across the NHS are safe, secure, and effective.
ORCHA supports suppliers and systems in understanding, completing, and maintaining DTAC compliance, using our globally recognised assessment methodology and review expertise.
For suppliers, DTAC is the gateway to NHS access. When a solution meets DTAC requirements, they can be positioned within ORCHA's Access solutions that reach thousands of NHS professionals and patients.
For commissioners and health systems, it offers assurance that products meet baseline digital health standards.
By meeting DTAC, suppliers demonstrate compliance with mandatory legal, regulatory, and best-practice requirements - enabling NHS organisations to procure with confidence.
To simplify assurance, strengthen trust, and accelerate the safe adoption of digital health solutions across the NHS
ORCHA has helped hundreds of digital health suppliers navigate DTAC — turning what can be a complex, self-assessed process into a clear, supported pathway.
Our assessment team uses the ORCHA Global Baseline Review (OBR) as a foundation, mapping it directly to DTAC requirements.
This enables us to:
Identify gaps between your product and DTAC standards
Provide clear, actionable feedback and a “success plan.”
Support submission readiness for NHS organisations
Maintain ongoing compliance through continuous monitoring
Faster, clearer, and more confident DTAC completion, backed by independent ORCHA validation.
DTAC reviews are completed as part of a wider ORCHA Assured process, giving you one pathway to both NHS and international recognition.
A validated DTAC submission accelerates NHS procurement, enabling faster onboarding through platforms such as ORCHA Compare.
Our frameworks underpin ORCHA Assured, a tiered certification that verifies digital health technologies against essential standards.
Bronze – confirms baseline compliance across privacy, safety, and usability.
Silver – adds deeper evidence and advanced usability checks.
Each ORCHA Assured product carries the ORCHA Guarantee - our commitment to independent, defensible assessment that reduces procurement risk and builds trust.
The Digital Technology Assessment Criteria (DTAC) is the NHS standard that ensures digital health technologies meet essential requirements for safety, security, and quality.
