The IDEH scale describes patterns of practice, not fixed traits. Introductory does not mean unintelligent. Developing does not mean failing. The scale describes what is currently visible in your collaboration behavior — and behavior is exactly what changes with deliberate practice.
The most useful part of the report is usually not your ratings — it is the developmental scaffolding in each domain and the closing training prompt. That is where the assessment converts from a snapshot into a starting point.
