The Patterns of Strengths and Weaknesses (PSW) model can be a powerful tool for understanding students and identifying learning disabilities. However, many school psychologists feel unsure about how to use the model, especially when trying to balance best practices with district expectations and limited time. If the PSW model leaves you feeling overwhelmed or confused, you’re not alone.
Here are three common mistakes school psychologists make when using the PSW model—and practical ways to avoid them.
Starting with the Scores Instead of the Referral Question
One of the biggest missteps in using the PSW model is beginning the evaluation with a predetermined list of assessments rather than starting with the why. When we jump straight into collecting scores without clearly defining the referral question, we risk ending up with a report full of data and no clear story.
Avoid it by:
Letting the referral question guide your assessment plan. Ask: What is the team hoping to understand? What’s already been tried, and what still feels unclear? Let curiosity shape your battery. Your analysis will be more focused, relevant, and helpful.
Trying to Prove a Pattern Instead of Discovering One
It’s easy to fall into the trap of “chasing a pattern.”. The goal, however, isn’t to manipulate scores into fitting a model; it’s to uncover meaningful consistencies between the student’s strengths, weaknesses, and instructional responses. When we’re focused on proving a learning disability using technical criteria alone, we lose sight of the student’s lived experience.
Avoid it by:
Approaching the PSW model with an open mind. Look for themes, not perfection. Trust professional judgment alongside standardized data. And when the profile isn’t clear? Say that. Ambiguity doesn’t mean failure; it often means a different support plan is needed.
Overloading Reports with Terminology and Underdelivering on Meaning
Another common pitfall is filling reports with impressive terminology that isn’t actionable. A technically accurate explanation of a student’s processing weakness is only useful if families and educators understand it and know what to do next.
Avoid it by:
Translating technical language into everyday terms. Think about how you would explain the student’s strengths and needs in an IEP meeting. And always connect patterns of strength and weakness to concrete recommendations—it’s where your insight becomes impact.
