PIE is one of the shorter progress note formats, and most people meet it because a supervisor or an agency told them to use it rather than because they chose it. It has three sections instead of four, which makes it quick to write and easy to get slightly wrong. This guide covers what belongs in each section, a full worked example, how it differs from SOAP and DAP, and the one naming confusion that catches social workers out.
What PIE stands for
PIE is a three-part progress note format:
- P, Problem: the issue this session addressed.
- I, Intervention: what you did about it.
- E, Evaluation: how the client responded, and what happens next.
There is no separate assessment or plan heading, so your clinical thinking and your next steps both live inside the Evaluation.
The three sections, step by step
Problem
Name the specific issue this session worked on, not the client's whole history. Tie it to the treatment plan where you have one, and number it if your agency numbers goals, since that makes the note auditable later.
Write the problem as it presented today. "Reported three nights of disrupted sleep since the court date" is a problem. "Anxiety" is a label.
Intervention
What you actually did. Name the specific technique rather than the broad modality, because "CBT" tells a reader nothing about the session and will not help you when you reread it in six weeks.
"Used a thought record to examine the prediction that the hearing would go badly" is an intervention. "Provided therapy" is not.
Include anything else you did that matters: a referral, a handout, a between-session task, a call to a family member with consent.
Evaluation
This is the section that carries the weight, and the one most often rushed.
Evaluation holds two things. First, how the client responded to the intervention, in observable terms. Second, what follows from that: whether the approach is working, what you plan next, and anything that changed in your clinical judgment.
Because PIE has no Plan heading, your next steps belong here. Some practitioners add a short Plan line at the end anyway, and that is fine, but check your agency's template before you invent a fourth section in a three-section format.
Always close the loop back to the Problem you opened with. A note where the Evaluation does not answer the Problem reads as two unrelated paragraphs.
A worked PIE note example
Anonymised and illustrative.
Client: adult, individual session
Date: session 7
Problem: Goal 2, sleep disruption. Client reported waking at 3am on four of the past seven nights, with rumination about an upcoming custody hearing. Reports functioning at work is slipping, with two missed deadlines this week.
Intervention: Reviewed the sleep log completed since last session. Used a thought record to examine the prediction "I will lose access completely", including evidence for and against. Introduced a worry-postponement window of 15 minutes at 6pm. Agreed client will continue the sleep log and trial the worry window nightly.
Evaluation: Client engaged readily with the thought record and was able to identify two pieces of contradicting evidence without prompting, which is a change from session 4 when the same exercise needed heavy scaffolding. Rated belief in the prediction as 80% at the start of the session and 55% at the end. Client was sceptical about the worry window but agreed to trial it. Sleep remains the limiting factor on daytime functioning, so the current focus is appropriate and will continue. Review the log at the next session. If waking has not reduced by session 9, discuss referral for a sleep assessment.
Notice the Evaluation does three jobs: it reports the response, it compares against an earlier session, and it says what happens next. That is what replaces the missing Assessment and Plan sections.
PIE vs SOAP, DAP and BIRP
- PIE: Problem, Intervention, Evaluation. Starts from the problem, with no separate plan section.
- SOAP: Subjective, Objective, Assessment, Plan. Splits what the client said from what you observed.
- DAP: Data, Assessment, Plan. Merges subjective and objective into a single Data section.
- BIRP: Behavior, Intervention, Response, Plan. Starts from observed behaviour rather than a named problem.
- GIRP: Goal, Intervention, Response, Plan. Starts from the treatment goal rather than the problem.
PIE and GIRP are close relatives pointed in opposite directions. GIRP opens with where the client is going, PIE opens with what is in the way. If your service is goal-driven and strengths-based, GIRP tends to fit better. If you are documenting against presenting problems, PIE is the closer match.
If you are still choosing between formats, we have full guides to SOAP, DAP, BIRP and PIRP notes, and a side-by-side comparison of the main formats.
Where PIE comes from, and when to use it
PIE began as a nursing charting method, built around the nursing process, and you will still meet it in its expanded form APIE, which adds Assessment at the front. It has since been picked up more widely, and most practice-software vendors now publish a PIE template alongside SOAP and DAP.
That history explains its shape. It is built for settings where each entry has to show that a named problem was addressed and acted on.
PIE suits you when the problem is the organising idea of your work: case management, nursing and allied health, and any service where notes are audited against a treatment plan. The Problem section gives an auditor an immediate anchor.
It is a weaker fit when you need to separate what the client told you from what you observed. SOAP exists precisely for that split, and PIE collapses it. It is also less common in talk therapy than SOAP or DAP, so if you are choosing freely rather than following an agency template, check what your supervisor and your payer expect before standardising on it.
The naming confusion worth knowing
In social work, PIE much more commonly means Person-in-Environment, a classification system for problems in social functioning. It was developed by James Karls and Karin Wandrei and published by NASW Press in 1994, with a second edition in 2008, and it classifies across four factors: social role functioning, the environment, mental health and physical health. It was designed to be used on its own or alongside the DSM and ICD.
It is not a progress note format, and the two share nothing but the letters.
This matters more than it sounds. If you work in social work and a supervisor asks for "a PIE", they are more likely to mean the classification system than a three-section note. Ask before you write, because getting it wrong produces a careful answer to a question nobody asked.
Common mistakes to avoid
Writing a diagnosis in the Problem section instead of what happened today. The diagnosis belongs in the record, not in every note.
Naming the modality rather than the technique in Intervention. "CBT" is not an intervention, it is a category.
Treating Evaluation as a summary. It is where your clinical reasoning goes, and a note without it is a list of activities.
Leaving out next steps because there is no Plan heading. The absence of the heading does not remove the obligation.
Letting the Evaluation drift away from the Problem. If the two do not connect, the note does not hold together.
Writing PIE notes faster with Soap Notes
A three-section note should take minutes, and it usually does not, because the structure lives in your head rather than on the screen. Soap Notes lets you save a PIE layout as a reusable template, so each session opens with the three headings already there and the previous note one click away for comparison. The format stops being something you remember and becomes something you fill in.
