From framework to classification practice.
The PHCF Classification Manual Version 1 provides the architecture, definitions, recording logic and guidance needed to apply the developmental system consistently.
A structured reference for classification practice.
The manual is designed in the tradition of classification references. It separates conceptual rationale from classification guidance and records uncertainty rather than hiding it.
The online manual provides direct access to the framework’s definitions, classification guidance, interpretive cautions and application resources, while stable releases preserve version history.
