What you will build

This is independent online study with complete written lessons, worked cases, practical tools, and two assessment forms. Video examples are optional; every teaching point is available in text.

You can use a safe personal training project or the supplied Analyst Route. No exercise requires provoking a problem, working through distress, or continuing when health, welfare, safety, or professional scope sets a boundary.
