What Is Sustained Shared Thinking?

If you work in the early years sector, or you are currently preparing for a job interview or an upcoming Ofsted inspection, you have almost certainly heard the phrase sustained shared thinking (SST).

It is one of those academic-sounding terms that frequently pops up in educational frameworks, training courses and staff meetings. But for many practitioners, it is a phrase that sounds incredibly important without ever feeling entirely clear.

• What does it actually mean on a Tuesday morning on the nursery floor? 

• What does it look like in reality?

• And how do you know if you are actually doing it properly?.

In this guide, we are going to strip away the academic jargon and break down sustained shared thinking in a simple, practical way so you can understand it, recognise it, and use it confidently in your day-to-day practice.

1. A Simple Definition of Sustained Shared Thinking

Let’s start with a definition that doesn’t require a textbook to decode.

Sustained shared thinking is when an adult and a child/ children work together to solve a problem, clarify a concept, or extend an narrative.

The magic of this concept lies entirely in three specific words:

1. Sustained: The interaction isn’t a quick, fleeting exchange. It lasts for a period of time; it has a beginning, a middle, and an end where ideas are explored deeply.

2. Shared: It is a two-way street. You are not just talking at the child, and the child isn’t just listening to you. You are actively thinking together.

3. Thinking: The focus is on cognitive development. You are helping the child process an idea, evaluate a problem, or stretch their imagination.

As highlighted in “What Is Continuous Provision Explained Simply for Early Years”, the environment sets the stage for independence, but it is the human interaction that elevates the learning. Sustained Shared Thinking is the bridge that takes a child’s independent play and expands it into deep, cognitive development.

2. Real-World Examples: The Shift in Practice

The easiest way to understand sustained shared thinking is to look at how a standard, everyday interaction can be upgraded into an SST moment.

Example A: Building a Tower

• The Standard Interaction: A child is stacking blocks. The adult walks past and says, “Wow, what a lovely big tower you’ve built!” The child smiles, the adult walks away. (This is nice encouragement, but it is not sustained shared thinking).

• The Sustained Shared Thinking Upgrade: The child is stacking blocks and it wobbles. The adult sits down, stays quiet for a moment, and observes. The adult then says, “I noticed it wobbled when you put that long block on top. I wonder why that happened?” The child looks at it and says, “It’s too heavy.” The adult responds, “Mm, it is heavy. What do you think we could do to make the bottom stronger so it doesn’t tip over?” Together, they experiment with different bases.

Example B: Observing Bugs in the Garden

• The Standard Interaction: A child points at a worm. The adult says, “Look, it’s a worm! It lives in the mud.” 

• The Sustained Shared Thinking Upgrade: The child points at a worm. The adult bends down and says, “Look how it stretches and shrinks to move. I wonder how it moves so fast without any legs?” The child pauses, looks closely, and says, “It slides like a snake.” The adult says, “It does look like a snake. Let’s see if it leaves a trail in the dirt like a snail does.”

In both upgrades, the adult isn’t providing the answer. They are acting as a partner in the child’s curiosity, helping them extend their own logic.

3. Common Mistakes That Kill Sustained Shared Thinking

Sustained Shared Thinking doesn’t fail because practitioners don’t care; it usually fails because of deeply ingrained habits that we do without realising. If you want to improve your interactions, watch out for these three “Sustained Shared Thinking Killers”:

• The Interrogation (Too Many Questions): Bombarding a child with closed questions (“What colour is that? How many have you got? What’s that called?”) feels like a test, not a conversation. It shuts down thinking rather than opening it up.

• Not Fully Listening: Hearing what a child says but not actually building on it. If a child says, “My dog went to the vet,” and the adult responds with, “That’s nice, now come and sit down for register,” the opportunity for shared thinking is gone.

• Interrupting Too Quickly: Jumping in to “fix” a problem before the child has had a chance to process it. Silence is an essential tool. Children need a pause to think.

To build a team that naturally avoids these pitfalls, leadership must model the right behaviour. 

4. How to Show “Exceptional” Interactions to Ofsted

Under the current inspection framework, Ofsted is heavily focused on the quality of education and individual interactions. They don’t want to see staged, overly formal lessons or rehearsed lines from your team.

When an inspector observes your room, they are actively looking for purposeful connection.

The Adult Role during Ofsted Observations:

1. Tune In: Show that you are genuinely interested in what the child is doing. Match their energy and focus.

2. Narrate and Comment: Instead of asking questions, describe what you see. “You are pushing that car really hard down the ramp.” This gives the child vocabulary without putting pressure on them to perform.

3. Wonder Out Loud: Use phrases like, “I wonder what would happen if…” or “I’ve never seen that before, I wonder why…” This invites the child to think with you.

5. The Golden Script: How to Explain Sustained Shared Thinking Simply

If you are ever in a job interview, a professional review, or an Ofsted inspector asks you to explain how you support child development, you do not need to give a long, academic answer.

Keep it simple and use this definition:

“Sustained shared thinking is when an adult and a child think together, sharing ideas and building on each other’s thinking to solve problems or explore concepts deeper.”.

It is clear, it is confident, and it shows you understand the practical application of child psychology rather than just memorising framework buzzwords.

Conclusion: Value the Small Moments

Sustained shared thinking isn’t an extra task you have to add to your busy nursery schedule. It is simply a shift in how you show up in the moments that are already happening. It’s about slowing down, tuning in, and valuing the child’s thought process as much as the end result.

When your team masters this approach, you will see a massive shift in children’s language development, confidence, and problem-solving skills.

Take Your Early Years Practice Further:

• Train Your Team: Access observation checklists and staff training audits inside our Nursery Documents section.

• Deepen the Concept: To see how this pairs with language development, read our guide on High-Quality Interactions in EYFS.

• Connect with Leaders: Share ideas and discuss pedagogical strategies in the Successful Early Years Owners Facebook Group.

• The Full Business & Practice Roadmap: Enrol in the complete How to Open a Nursery Course (£249.99) to master everything from financial sustainability to outstanding childcare delivery.

Confidence comes from clarity. Once you understand the “why” behind your interactions, your everyday practice becomes truly purposeful.
