# Maturity Levels for Members (National Release Center)
The SNOMED CT Implementation Maturity Levels for Members (National Release Centers), highlights how adoption evolves at a national or regional level. It shows the progression from no coordinated activity to a fully optimized ecosystem where SNOMED CT is widely implemented, governed, and leveraged for advanced use. The model emphasizes how Members can progressively strengthen governance frameworks, expand adoption across affiliates, align with national health strategies, and enable interoperability and secondary use to support data-driven healthcare at scale.
Maturity Level Descriptions
#### Level 0 – None
* No national adoption initiatives or formal recognition of SNOMED CT
* No governance structures, policies, or assigned responsibilities
* No awareness, capability, or stakeholder engagement
* Health data primarily uses local or non-standardized terminologies
* No infrastructure or support for terminology services
***
#### Level 1 – Basic
* Awareness of SNOMED CT exists at a national level
* Limited or informal discussions among key stakeholders
* No coordinated national program or implementation roadmap
* Minimal engagement with international standards or communities
* Early understanding of potential benefits, but no structured action
***
#### Level 2 – Emerging
* National strategy for SNOMED CT defined or in development
* Initial pilot projects or early adopters (e.g., selected organizations)
* Early governance structures, roles, and responsibilities beginning to form
* Initial stakeholder engagement and awareness-building activities
* Exploration of infrastructure needs (e.g., terminology services, extensions)
***
#### Level 3 – Advanced
* Increasing number of affiliates actively using SNOMED CT
* Formal governance structures established, including policies and oversight
* National guidance, standards, and support resources available
* Monitoring and reporting mechanisms introduced to track adoption
* Training programs and stakeholder engagement initiatives in place
* Early interoperability initiatives emerging across systems
***
#### Level 4 – Integrated
* Majority of target organizations adopting and using SNOMED CT consistently
* Strong governance with active stakeholder participation
* Alignment with national digital health strategies and regulatory frameworks
* Interoperability enabled across systems through standardized implementation
* Measurable improvements in data quality, consistency, and exchange
* SNOMED CT used for analytics, reporting, and decision-making
***
#### Level 5 – Optimizing
* Full national adoption across affiliates and healthcare sectors
* Continuous monitoring, evaluation, and improvement embedded in governance
* Mature infrastructure supporting terminology services and national extensions
* Advanced secondary use of data (analytics, research, population health, AI)
* Strong ecosystem collaboration across stakeholders
* Recognized leadership in terminology governance and international best practices

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.snomed.org/snomed-ct-practical-guides/implementation-maturity-framework-guide/framework-design/maturity-levels/maturity-levels-for-members-national-release-center.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
