Play Therapy Assessment Explained: How to Know If Your Play Therapy Sessions Are Working

The missing piece that helps you stop guessing, feel more confident, and get better outcomes for your clients.

If you’ve ever found yourself wondering…

👉 “Is this actually working?”
👉 “Am I helping this child… or just hoping I am?”

You’re not alone.

This is one of the most common questions I hear from play therapists—whether you’re brand new or have been doing this for years.

And most of the time, it doesn’t come from lack of skill or care.

It comes from something much simpler:

👉 You don’t have a clear assessment process guiding your work.

What “Assessment” Actually Means in Play Therapy

When we hear the word assessment, a lot of us immediately think of formal testing or long, clinical evaluations.

But in play therapy, assessment is much broader than that.

At its core, assessment is simply:

👉 Gathering the right information so you can understand what’s really going on with your client—and know how to help them.

It’s the foundation for everything that comes after.

Because if you don’t understand the problem…

How can you possibly target the right solution?

What Happens When You Skip This Step

I see this all the time—especially with newer play therapists (but honestly, experienced therapists fall into this too).

You want to help.

You want to get started.

So you jump right into sessions.

And then a few weeks—or months—later…

You feel stuck
You’re trying different activities
You’re second-guessing yourself
You’re wondering why progress feels slow (or unclear)

This is what happens when assessment gets rushed or treated like “just paperwork.”

Because without it, you’re essentially guessing.

A Simple Way to Think About It

Let me give you a real-world analogy.

If your car breaks down and you take it to a mechanic…

You wouldn’t want them to just start fixing random parts without asking questions, right?

You’d expect them to:

Ask what’s happening
Listen to the symptoms
Diagnose the problem
Then fix the right thing

The same is true in play therapy.

👉 Assessment is your diagnostic process.

Without it, even great interventions can miss the mark.

The Two Types of Assessment You Should Be Using

1. Informal Assessment (What You’re Already Doing—But Maybe Not Intentionally)

This includes:

Your intake (bio-psychosocial, cultural, developmental)
Parent interviews
Observations in session
Play themes
Behavior patterns over time

But here’s the key:

👉 It’s not just what you ask—it’s how well you understand what you’re hearing.

Because if you don’t know what to listen for…

You can still miss what matters most.

2. Formal Assessment (When You Need More Data)

There are also structured tools—like symptom questionnaires—that can:

Help you catch things you might miss
Track progress over time
Give both you and parents more clarity

Even simple screening tools can be incredibly powerful when used consistently.

And sometimes?

They confirm what you’re seeing.

Other times?

They show you something you didn’t catch yet.

Why Assessment and Case Conceptualization Go Hand-in-Hand

Here’s where everything comes together.

Assessment is how you gather the data.

👉 Case conceptualization is how you make sense of it.

I like to think of them like peanut butter and jelly.

You can have one without the other…

…but they work a whole lot better together.

Because once you understand:

What’s driving the behavior
What patterns are maintaining it
Why it’s happening now

Then you can actually create a treatment plan that makes sense.

Why This Matters More Than You Think

Let’s take a common example:

An 8-year-old with:

Daily meltdowns
Aggression
Emotional dysregulation

At first glance, this might all look the same.

But the root could be:

ADHD
Anxiety
Trauma
Attachment disruptions
Sensory processing issues
Or a combination of several

And if you don’t assess thoroughly?

👉 You risk targeting the wrong thing.

Which is why you might feel like:

“Nothing is working”
“I’m missing something”
“I don’t know what to do next”

When in reality…

You just need better information.

Assessment Doesn’t Stop After Intake

This is another big mindset shift.

Assessment is not a one-time event.

👉 It’s ongoing.

Every session gives you more data:

Play themes
Relationship patterns
Emotional responses
Shifts over time

I always say:

👉 You are a mental health detective.

You’re constantly gathering clues, testing hypotheses, and adjusting your understanding.

Especially in the first 90 days, where you’re really building clarity around what’s going on.

When You Should Refer Out

There are times when assessment needs to go beyond your scope.

For example:

Suspected ADHD or autism
Learning challenges
Sensory processing issues
Developmental delays

In those cases, referring to:

Clinical psychologists
Occupational therapists
Speech or developmental specialists

…can be incredibly helpful.

Because your role in play therapy is not to diagnose everything.

👉 It’s to treat what’s within your scope—like emotional regulation, anxiety, trauma, and relational patterns.

Why This Changes Everything

When you strengthen your assessment skills:

You stop guessing
You feel more confident
Your imposter syndrome decreases
Your sessions become more intentional
Your outcomes improve

And most importantly…

👉 You can actually see the progress you’re making with your clients.
