BIRP and DAP are both widely used therapy note formats — and they share enough structural overlap that clinicians sometimes wonder whether there is a meaningful difference worth caring about. The short answer is yes: BIRP has four sections and explicitly documents the interventions you used and how the client responded to them, while DAP has three sections and takes a more streamlined approach that combines session data without separating out the clinical interventions.
This article explains each format, compares them directly, shows the same session documented in both styles, and offers practical guidance for choosing the right format for your setting.
DAP stands for Data, Assessment, and Plan. The format organizes session documentation into three sections, combining the client's self-reported content and the clinician's direct observations into a unified Data section. Many therapists prefer DAP because it removes the need to decide whether a given piece of information is "subjective" or "objective." For a detailed example, see the DAP Note Example for Therapy. Here is what each section contains:
Everything clinically relevant from the session — both what the client reports (subjective) and what you directly observe (objective). DAP combines these into a single Data section, simplifying the structure. Include the client's stated concerns, affect, behavior, and any notable changes since the last session.
Your clinical interpretation of the Data. Analyze the client's current status in relation to their treatment goals, document progress or setbacks, and record your clinical reasoning. Assessment should be grounded in what you observed and reported — not a restatement of it.
Specific next steps for treatment. Document the interventions you'll continue or introduce, any between-session assignments, referrals, and the timing of the next appointment. A useful Plan section is concrete enough that another clinician reading the record could understand what comes next and why.
BIRP stands for Behavior, Intervention, Response, and Plan. The format is structured around the clinical process of the session: what the client presented, what the therapist did, how the client responded, and what comes next. The defining feature of BIRP is the explicit Intervention section — a dedicated place in the note to document which therapeutic techniques were used during the session. For a full example with template, see the BIRP Note Example for Therapy. Here is what each section contains:
The client's presentation, reported concerns, symptoms, and observable behavior during the session. Similar in scope to DAP's Data section, but explicitly named Behavior to focus attention on what is observable and reportable — affect, mood, engagement, and any significant events the client discloses.
The specific clinical interventions you used during the session. This is the defining difference between BIRP and DAP: BIRP requires an explicit account of what the clinician did — which techniques were employed, which topics were addressed therapeutically, and how the session was structured. Settings that need to demonstrate medical necessity often value this level of intervention detail.
The client's response to the interventions documented in the I section. Did the client engage with the technique? Was there resistance, breakthrough, or minimal engagement? This section captures the outcome of the session's clinical work and informs the assessment of progress.
Specific next steps for treatment. Document the interventions to continue or introduce, any between-session assignments, referrals, and the timing of the next appointment. The BIRP Plan section serves the same purpose as the Plan in DAP — it should be concrete and actionable.
The structural difference between BIRP and DAP reflects a difference in emphasis rather than a difference in clinical completeness:
Structure
3 sections: Data, Assessment, Plan
Documents interventions explicitly
No — interventions may appear in Data or Plan but are not a dedicated section
Best for
General outpatient therapy; settings with straightforward documentation requirements
Common in
Private practice outpatient therapy
Structure
4 sections: Behavior, Intervention, Response, Plan
Documents interventions explicitly
Yes — a dedicated Intervention section captures what techniques were used
Best for
Settings requiring intervention tracking or heightened medical necessity documentation
Common in
Behavioral health, community mental health, Medicaid-funded programs
The following examples document the same clinical scenario — an adult client presenting with work-related anxiety — using both DAP and BIRP. Reading them together makes the structural difference concrete and helps illustrate when BIRP's Intervention and Response sections add meaningful documentation value.
Client reports continued stress related to workload, describing it as "unmanageable." Disclosed a conflict with supervisor earlier in the week and expressed frustration and self-doubt. Reports difficulty sleeping, averaging 5 hours per night, and daytime fatigue. Client appeared tense on arrival; affect was anxious and constricted. Speech was slightly pressured when discussing work but normalized during the latter half of the session. Engaged cooperatively throughout.
Client continues to experience symptoms consistent with mild generalized anxiety, currently exacerbated by occupational stressors. Sleep disturbance appears to be a maintaining factor. Client demonstrated improved ability to identify cognitive distortions during session — progress toward the treatment goal of increased cognitive flexibility. Self-critical thinking remains prominent. No safety concerns.
1. Continue CBT-focused interventions targeting cognitive restructuring of work-related stress. 2. Assign thought record worksheet to track automatic thoughts before next session. 3. Introduce sleep hygiene psychoeducation; provide written handout. 4. Continue weekly sessions. Next appointment scheduled for [date].

Utilized cognitive restructuring to identify and examine automatic thoughts related to work performance and the supervisor conflict. Collaboratively reviewed a recent example of self-critical thinking and guided client through examining evidence for and against the belief. Psychoeducation provided regarding the relationship between sleep and anxiety symptoms. Introduced rationale for thought record homework.
Client engaged well with cognitive restructuring exercise and was able to identify two alternative interpretations of the supervisor conflict with minimal prompting — a notable improvement from prior sessions. Expressed some skepticism about thought records but agreed to try the assignment. Affect visibly less constricted by end of session. No safety concerns identified.

In the BIRP note, the Intervention section makes the clinical work visible in a way that the DAP note does not require. The Response section captures the client's reaction to that specific work — information that in a DAP note might appear embedded within the Assessment or not at all. Whether that granularity is necessary depends on your setting.
The right format depends more on your setting and documentation requirements than on personal preference. Here are the most useful factors to consider:
Check your setting's documentation requirements
Community mental health centers, behavioral health agencies, and Medicaid-funded programs sometimes specify BIRP or a similar format that explicitly documents interventions. Review your agency's policies or payer contracts before choosing.
BIRP is stronger for medical necessity documentation
Because BIRP explicitly captures what interventions were used and how the client responded, it provides a clearer audit trail for demonstrating that services were medically necessary and clinically appropriate. This can be valuable in settings with heightened payer scrutiny.
DAP is simpler and typically faster to write
DAP's three-section structure removes the need to separately document interventions and client response, which reduces the number of decisions per note. For private practice clinicians with lighter payer documentation requirements, DAP is often the more efficient choice.
Both formats are clinically sound
Neither BIRP nor DAP is inherently more rigorous — they are different tools for different contexts. DAP covers the same essential clinical information more concisely; BIRP provides more granularity around clinical process.
Consider what your supervision and peer review require
If you are supervised or if your notes are reviewed regularly, the format your supervisor or clinical director prefers matters. Using a consistent format across a practice or program makes review significantly easier.
Regardless of which format you use, the practical challenge is often the same: completing notes consistently, accurately, and without spending more time on documentation than on clinical work. Some therapists find it useful to separate the capture step — getting clinical content down right after a session — from the formatting step, which can happen shortly after.
Tools like AfterSession support both BIRP and DAP formats, allowing clinicians to select whichever structure fits their setting and generate a structured draft from a brief session summary. The clinician reviews and edits the draft before saving — maintaining authorship while reducing the time spent on formatting.
BIRP's explicit Intervention and Response sections can make it easier to demonstrate medical necessity to payers, since the record clearly shows what treatment was provided and how the client responded. DAP is also widely accepted by most insurance companies, but the clinical reasoning behind the session's work may be less immediately legible in the note. If your payer requires detailed intervention documentation, BIRP may be the stronger choice. When in doubt, review your specific payer contracts or contact your payer's provider relations team.
Most clinicians find DAP slightly faster to write. The three-section structure means fewer decisions per note, and the Data section allows you to capture session content without separately categorizing interventions and responses. BIRP requires you to explicitly document what techniques you used and how the client responded, which adds writing time but also adds specificity. For clinicians accustomed to BIRP, the structure can actually speed up writing by providing a clear framework for each section.
You can, but it is generally better to use a consistent format throughout each client's record. Mixing formats within a single client's chart can make it harder to track progress over time and may complicate record review or audits. If your setting allows format flexibility across clients, that is reasonable — just apply one format consistently per client from intake onward.
Not universally, but BIRP or similar intervention-focused formats are more common in community mental health, behavioral health agencies, and programs funded through Medicaid or other public payers. These settings often have heightened documentation requirements around medical necessity and treatment fidelity, and BIRP's explicit Intervention section supports those requirements. If you work in a community mental health setting, check your agency's clinical documentation standards rather than assuming either format is acceptable.
BIRP and DAP are both clinically sound formats. The choice between them is primarily a function of your setting's documentation requirements. DAP's simpler three-section structure works well in most private practice and outpatient contexts. BIRP's explicit Intervention and Response sections are better suited to settings where demonstrating the specifics of clinical work — what techniques were used and how the client responded — matters for medical necessity, supervision, or payer compliance.
If you are unsure which format fits your context, check your agency's policies, review your payer contracts, and consider what your supervisor or clinical director expects. In most cases, the best format is simply the one you will write consistently and accurately for every session.
