Progress notes are a legal record, a clinical tool, and the thing you have to write at the end of every session whether you have five minutes or fifty. The format you use matters, and not just for compliance. A good format helps you think clearly about what happened in a session. A bad fit produces notes that are technically complete but clinically useless.
SOAP, DAP, and BIRP are the three formats you'll encounter most in outpatient mental health practice. Here's what each one actually means, where it works best, and how to decide which one belongs in your practice.
SOAP notes
SOAP stands for Subjective, Objective, Assessment, Plan. It came out of medical practice and is the oldest and most widely recognized format in healthcare.
Subjective
What the client reported. Their words, their experience, their account of how things are going. This is not your interpretation. It's what they said. "Client reported difficulty sleeping for the past week and described feeling 'wound up' most evenings."
Objective
What you observed. Appearance, affect, behavior, engagement. Things a third party in the room could have seen. "Client appeared well-groomed. Affect was mildly constricted. Maintained consistent eye contact throughout session."
Assessment
Your clinical interpretation. How you make sense of what the client reported and what you observed. Progress toward treatment goals, clinical impressions, any diagnostic considerations. This is where your professional judgment lives.
Plan
What happens next. Interventions used in the session, homework or between-session tasks, any referrals or coordination, and the plan for the next session.
DAP notes
DAP stands for Data, Assessment, Plan. It was developed specifically for mental health settings as a streamlined alternative to SOAP, collapsing the Subjective and Objective sections into a single Data section.
Data
Everything you would have put in Subjective and Objective combined. What the client said and what you observed, written together without the artificial separation between reported experience and clinical observation. Many therapists find this more natural, since in a therapy session the two are often deeply intertwined.
Assessment
Same as in SOAP. Your clinical interpretation of the session, progress, and any impressions worth documenting.
Plan
Same as in SOAP. Next steps, interventions, follow-up.
BIRP notes
BIRP stands for Behavior, Intervention, Response, Plan. It was designed with a specific focus: documenting what the therapist did and how the client responded to it, which makes it particularly useful for demonstrating clinical progress to insurers and reviewers.
Behavior
How the client presented at the start of the session. Their mood, affect, reported symptoms, and anything clinically relevant they brought in. Similar to the Data section in DAP, but with an emphasis on observable and reported behavior.
Intervention
What you did as the clinician. The specific techniques, modalities, and therapeutic approaches used in the session. This is the section that makes BIRP distinctive. "Therapist utilized cognitive restructuring techniques to address client's catastrophic thinking patterns around job performance."
Response
How the client responded to your interventions. Did they engage? Did they push back? What shifted, if anything? This section captures the therapeutic process in a way the other formats don't emphasize.
Plan
Next steps, as in the other formats.
How to choose
There is no universally correct format. The right choice depends on your setting, your payers, and what helps you think clearly about your clinical work.
- If you bill insurance or run a private pay practice: SOAP is the standard. It is what insurance reviewers, auditors, attorneys, and licensing boards recognize. When in doubt, SOAP is the safe default.
- If you work in an agency or community mental health setting: Your organization likely has a required format. If BIRP is what your agency uses, it is well suited to the documentation demands of those settings.
- If you find SOAP feels forced for talk therapy: DAP is a reasonable alternative. It combines the Subjective and Objective sections into a single Data section, which many outpatient therapists find more natural. It is still widely accepted for private pay documentation.
- Whatever format you use: Make sure the Assessment and Plan sections are specific. Vague notes are the most common reason claims get flagged and the weakest point in any audit.
The format is not the hard part
Choosing between SOAP, DAP, and BIRP is a smaller decision than most therapists make it. Any of them, done well, will produce legally defensible, clinically useful documentation. The harder challenge is writing notes that are specific, timely, and actually reflect what happened in the session, rather than notes that technically check every box while saying nothing.
A note written thirty minutes after a session is almost always better than one written the next morning. A note that uses the client's actual language is almost always better than one written in abstracted clinical terminology. Whatever format you use, those habits matter more than the structure itself.
