1. Introduction

The authoring level 2 certification recognizes your competence in performing advanced SNOMED CT authoring tasks. The authoring level 2 competencies represent:

The set of knowledge and skills that are considered necessary to achieve an advanced level of authoring competence
The minimum requirements needed to pass the authoring level 2 certification exam
The context in which the questions and tasks for the authoring level 2 course and certification exam have been developed.

The key competency categories are:

1. Design Principles of SNOMED CT	SNOMED CT design to meet the fundamental principles of modern medical terminology and why this is important
2. SNOMED CT Content	SNOMED CT content coverage, structure and use case
3. Content Request Process	SNOMED CT content development, request submission and request submission management process
4. SNOMED CT Concept Model	Purpose and features of the SNOMED CT concept model and Machine Readable Concept Model
5. Editorial Guidance	SNOMED International Editorial Guide and other guides
6. SNOMED CT Authoring	Required tasks in creating and revising SNOMED CT concepts
7. Terminology Processes	Authoring Process, Quality Assurance, Release Process, Release Validation, ECL and Translation

Further details of the competencies belonging to each category are provided in the subsequent sections of this Ebook.

The level of competency is based on the Revised Bloom Taxonomy (6 levels)

1) Remember – Retrieve relevant knowledge from long-term memory

2) Understand – Determine the meaning of instructional messages, including oral, written, and graphic communication

3) Apply – Carry out or use a procedure in a given situation

4) Analyze – Break material into its constituent parts and detect how the parts relate to one another and to an overall structure or purpose

5) Evaluate – Make judgments based on criteria and standards

6) Create – Put elements together to form a novel, coherent whole or make an original product

Please Note: The Authoring Level 2 Course and Certification exam only require the authoring of content in the Procedure, Clinical finding and Situation with explicit context hierarchies.
