Dynamic assessment – Let’s look beyond the checklist

As a parent, you’re always observing your child, celebrating his or her milestones, and sometimes, wondering if he or she is quite on track. When it comes to speech, language, play, attention, and listening, these early years are a whirlwind of development! It’s natural to seek guidance if you have concerns, and that’s where a truly comprehensive assessment comes in.
But what exactly does ‘comprehensive’ mean, especially when it goes beyond a typical checklist? You can find any number of check lists online these days but whilst they can give you an overall idea of what a child is typically expected to do at any given age, it can also start leading you into a rabbit hole of anxiety of ‘what-iffery’.
At The London Speech and Feeding Practice I believe in something far more insightful than a static evaluation: Dynamic Assessment. Think of it as an in-depth, interactive investigation into your child’s unique communication landscape, exploring not just what he or she can do, but how he or she learns and why he or she might be facing challenges. This is so important.
What makes an assessment ‘dynamic’?
Imagine trying to understand a child’s personality by just looking at a single photograph. It gives you a glimpse, but it hardly tells the whole story. Traditional, formal assessments, while valuable, can sometimes be like that photograph – a snapshot of skills at one specific moment.
Dynamic assessment, on the other hand, is a living, breathing process. It’s called ‘dynamic’ because:
- It’s interactive and responsive: It adapts to your child’s needs in real-time. It’s not about sticking rigidly to a pre-set schedule of tests. Instead, it’s about observing, gently prompting, and providing support to see how your child responds and learns. This allows me to understand his or her learning potential, not just his or her current performance.
- It’s holistic and multi-faceted: I look at the whole child. We delve deep into not just speech and language, but also his or her play skills (a crucial window into cognitive and social development), attention and listening abilities, and his or her social engagement. These areas are intricately linked, and a delay in one can often impact others.
- It integrates multiple perspectives: Your insights as a parent are invaluable! Before we even meet, my comprehensive onboarding questionnaire gathers essential background. During the assessment, your feedback, observations, and comments are woven into the fabric of our session. You are the expert on your child, and your voice is central to forming a complete picture.

More than just ‘speech’: A deep dive into development
You might initially be concerned about your child’s speech sounds, or perhaps his or her ability to form sentences. These are vital areas, but my approach goes much further. I’m keen to understand:
- The ‘why’ behind the ‘what’: Is a child struggling with language because of difficulties with understanding instructions (receptive language), or with expressing themselves (expressive language)? Are his or her attention skills impacting his or her ability to follow a conversation? Is his or her play demonstrating imaginative thought, or does he or she prefer more structured, repetitive activities? These nuances are critical.
- Differential diagnosis: This is where the skill of an experienced clinician truly comes into its own. Through dynamic assessment, I can differentiate between a developmental delay (where a child is following a typical progression but at a slower pace) and a disorder (where his or her development is following an atypical pattern). This distinction is vital because it guides the type of support and intervention that will be most effective. Understanding the cause of the delay or disorder is paramount to creating a targeted, impactful therapy plan.
The art of observation
While I draw upon evidence-based practice as well as a formal, standardised assessment as well as my extensive clinical knowledge, I also rely heavily on the art of observation. From the moment your child walks into the room, I’m establishing rapport, engaging them in play, and creating a safe, fun environment. It’s through this genuine interaction – often without them even realising they’re being ‘assessed’ – that the most authentic insights emerge.
This is where the magic happens:
- Building rapport: A child who feels comfortable and connected will show you so much more of his or her true abilities and personality. I pride myself on creating an atmosphere where children can relax and simply be themselves.
- Play as a window: Play isn’t just fun; it’s a child’s natural language. It reveals his or her understanding of the world, his or her problem-solving skills, his or her social engagement, and his or her ability to use symbols and language.
- Skilled interpretation: My years of experience allow me to see beyond surface-level behaviours and interpret the subtle cues that might indicate underlying strengths or challenges. This goes far beyond what any standardised test alone can capture.
Why choose a clinician who offers dynamic assessment?
In essence, a dynamic assessment provides a rich, nuanced, and truly personalised understanding of your child. It’s an investment in:
- Accuracy: Leading to a more precise diagnosis and understanding of his or her unique profile.
- Tailored support: Enabling the creation of highly individualised therapy goals that truly meet your child where he or she is and gently guide him or her forward.
- Empowerment: You’ll leave with not just answers, but also practical strategies and a clear path forward, feeling confident and informed.
