Definition
The DAP format organizes each session note into three blocks: Data (all information gathered during the session — both what the client reports and what the professional observes), Assessment (the professional's clinical reading of the client's current state), and Plan (the agreed steps for the next session or between-session period). It is the more compact alternative to SOAP.
How it's used
The Data section is intentionally broad: it includes direct client quotes, the professional's observations about their emotional or behavioral state, and results from any instrument administered. By combining the subjective and objective into a single block, the note flows more narratively and is preferred by those who find the S/O separation in SOAP artificial.
The Assessment section follows the same pattern as in SOAP: clinical hypotheses, risk level, progress toward goals, differential diagnosis when relevant. The professional articulates their reasoning here.
The Plan section closes the note with concrete actions: techniques for the next session, assigned tasks, coordination with other professionals, and any adjustments to the therapeutic contract.
When to apply
DAP is particularly popular in clinical social work and community mental health services where documentation time is tight. Its three-section structure reduces friction around deciding whether something belongs in "S" or "O," which speeds up the writing process without sacrificing clarity.
Historical origin
The DAP format emerged as a practical simplification of SOAP within mental health contexts. It is widely adopted in the US and Canada, particularly in publicly funded mental health programs where documentation efficiency is critical. It has no single documented inventor.
How CauceOS supports it
CauceOS's DAP template condenses the session transcript into three blocks with an emphasis on narrative. The system automatically identifies the professional's interventions and the client's themes, distributing them across Data and Assessment as an editable draft. The professional adds their analysis and adjusts the Plan before exporting.
