SOAP and BIRP are two of the most widely used therapy note formats. SOAP separates client report from clinician observation; BIRP foregrounds the intervention–response cycle. Both are clinically valid — the right choice depends on your setting and what you want the chart to make easy to find later.
This guide compares the two formats section by section, explains when each is the right fit, and shows the same session documented in both formats so you can see the structural difference directly.
Start Free TrialBoth formats use four named sections, but they organize the clinical content differently.
| SOAP | BIRP | |
|---|---|---|
| Section 1 | Subjective (client report) | Behavior (client presentation) |
| Section 2 | Objective (clinician observation) | Intervention (technique used) |
| Section 3 | Assessment (interpretation) | Response (client reaction) |
| Section 4 | Plan (next steps) | Plan (next steps) |
| Best for | Structured clinical environments | Behavioral health, intervention tracking |
| Strength | Separates report from observation | Tracks what worked across sessions |
Client report and observation
SOAP splits this into Subjective and Objective — two distinct sections. BIRP merges both into a single Behavior section. Practical effect: BIRP loses the explicit client/clinician boundary, but is faster to write because you're not separating who-said-what.
Where interventions live
In SOAP, interventions are documented in Plan — sometimes alongside next-steps content. In BIRP, interventions get their own dedicated section (Intervention) followed immediately by Response. That dedicated section is BIRP's main strength: it makes intervention tracking explicit across the chart.
Where clinical interpretation lives
SOAP has a dedicated Assessment section for clinical formulation, diagnosis, and progress reasoning. BIRP doesn't have an equivalent — clinical interpretation tends to surface inside Response or get omitted. For settings that want explicit clinical reasoning visible in the chart, SOAP is stronger.
Plan section
Identical in both formats — next steps, homework, follow-up cadence, referrals.
Choose SOAP when you're in a structured clinical environment, when multiple providers review the same chart, or when supervisor and insurance review benefits from explicit separation of client report and clinician observation. SOAP also fits modalities where clinical interpretation and case formulation are central — psychodynamic, humanistic, or integrative therapy. SOAP is the most universally recognized format and is the safe default in any setting where you don't have a specific reason to use something else.
Choose BIRP when you work in behavioral health, substance use, intensive outpatient, or any setting where the chart needs to demonstrate which interventions are working session by session. BIRP fits behavioral and skills-based modalities best — CBT, DBT, behavioral activation, exposure work, and contingency management. The Intervention–Response pairing makes treatment effectiveness easy to scan across the chart, which is particularly valuable in settings with utilization review or program-level outcome tracking.
The same session documented in both formats — an adult client with generalized anxiety disorder showing measurable improvement.
SOAP Format
S: Reports anxiety as 5/10 (down from 7/10). Used breathing exercise before stressful work meeting.
O: Affect brighter than prior session. GAD-7 score 11 (down from 15 at intake). Engaged actively.
A: GAD, moderate, with measurable improvement on CBT. Skill generalization evident — applying breathing in real-world triggers without prompting. Progress consistent with goal #1.
P: Continued cognitive restructuring. Assigned thought record. Re-administer GAD-7 in 2 weeks.
BIRP Format
B: Client reports anxiety 5/10 (down from 7/10). Affect brighter than prior session. GAD-7 score 11 (down from 15 at intake). Engaged actively.
I: Continued cognitive restructuring. Walked through evidence-for/evidence-against worksheet on catastrophizing thoughts about upcoming work review.
R: Identified two automatic thoughts and produced balanced alternatives. Reported decreased anxiety by end of exercise. Skill generalization evident — used breathing in real-world trigger without prompting.
P: Assigned thought record. Continue weekly. Re-administer GAD-7 in 2 weeks.
Same content, different organization. The SOAP version explicitly separates what the client said from what the clinician observed and what the clinician interpreted. The BIRP version foregrounds what the clinician did and how the client responded.
Yes, but consistency within a single client's chart is preferred. Some clinicians use BIRP for behavioral health groups and SOAP for individual therapy, but switching mid-treatment for the same client makes the chart harder to review. Most insurance reviewers and supervisors accept either format as long as it's used consistently.
Insurance reviewers accept both. They check for medical necessity, specific named interventions, treatment plan alignment, and progress tracking — not the format itself. SOAP is more universally recognized; BIRP is common in behavioral health and substance use settings.
Comparable. BIRP merges client report and observation into the Behavior section, similar to how DAP merges Subjective and Objective into Data. The trade-off is the same: BIRP is slightly faster than SOAP for most clinicians, especially when the session is intervention-focused. Speed differences between the two are small.
Possible but not ideal. Format switches mid-treatment make the chart harder to review and can raise questions during audits. If you do switch, pick a clean transition point (a clinical change, treatment plan revision, or transfer of care) and document the rationale briefly in the first note of the new format.
It can, but the fit is weaker. BIRP foregrounds the intervention–response cycle, which is most natural for behavioral and skills-based modalities (CBT, DBT, behavioral activation, exposure work). For psychodynamic, humanistic, or insight-oriented modalities, SOAP often fits better because the focus isn't necessarily on discrete interventions and measurable responses.
