Observe whether the child: hears and says the initial sound in words.
What it looks like
Three ways this behaviour shows up as a child grows. Each level includes everyday moments to watch for.
Emerging
Just starting
Sometimes identifies the initial sound in very familiar words (often their own name) with adult support, but is inconsistent and may confuse sound with letter name.
What you might see
When asked "What sound starts 'sun'?", the child answers "sun" or says an unrelated sound.
Sorts objects by meaning (all animals together) rather than by initial sound even after the adult models a sound sort.
Can sometimes say the first sound of their own name or a favourite character when the adult stretches it ("Sssssam").
Says the letter name instead of the sound (e.g., says "ess" for /s/) and needs correction to give the sound.
Expected
On track
Identifies and says the initial sound for many familiar words during play and routines when prompted, with occasional errors for blends/digraphs.
What you might see
When prompted, says the initial sound for common objects ("ball" → /b/, "cat" → /c/) but may slip on "ship" or "train".
Plays a "find something that starts with /m/" game and finds a matching object in the room with some trial and error.
Exceeding
Going further
Consistently hears and states the initial sound in a wide range of words (including less familiar) and uses this awareness when choosing letters in early writing.
What you might see
Quickly states initial sounds for a variety of words in conversation or book talk (e.g., "frog" starts with /f/).
During writing, chooses a plausible starting letter based on the first sound they hear (writes "b" for "bike" without being told).
Self-corrects an initial-sound answer (starts to say /p/ then changes to /b/ after repeating the word slowly).
Explains a sound match to someone else ("It starts with /s/ like 'sock'") or leads a simple sorting game by initial sounds.
Try this at home
Small everyday moments where you can notice this behaviour without setting up anything special.
At breakfast, pick a food and ask: "What sound does 'toast' start with?" Notice whether your child gives the sound, not just the letter name.
While reading, pause on a pictured word and ask: "What’s the first sound in 'bear'?"
During tidy-up, play: "Put all the /b/ things in this box" and see whether your child can find items by initial sound.
In the bath, try a quick game: "I’m thinking of something that starts with /s/" (soap, sponge). Watch whether your child suggests a matching item.
When your child writes or draws, ask: "What sound do you hear at the start of that word?" and observe whether they choose a starting letter to match.

The framework source and supporting developmental research.
Framework source
Development Matters in the Early Years Foundation Stage (EYFS) (2012), Literacy: Writing (40–60+ months).
Includes initial-sound awareness as a typical step within the 40–60+ month writing progression.
Developmental research
National Reading Panel. (2000). Teaching Children to Read: An Evidence-Based Assessment of the Scientific Research Literature on Reading and Its Implications for Reading Instruction (NICHD). (Phoneme isolation as a common phonemic awareness task.)
Places initial-sound (phoneme isolation) skills within phonemic awareness, which supports early reading and spelling development.

The full progression underlying the three levels above. Used by the platform’s reasoning agent when planning activities and observations.
Not Yet
Does not reliably notice the first sound in a spoken word; answers with the whole word or a letter name unrelated to the sound.
When asked "What sound starts 'sun'?", the child answers "sun" or says an unrelated sound.
Sorts objects by meaning (all animals together) rather than by initial sound even after the adult models a sound sort.
Emerging
Sometimes identifies the initial sound in very familiar words (often their own name) with adult support, but is inconsistent and may confuse sound with letter name.
Can sometimes say the first sound of their own name or a favourite character when the adult stretches it ("Sssssam").
Says the letter name instead of the sound (e.g., says "ess" for /s/) and needs correction to give the sound.
Developing
Identifies and says the initial sound for many familiar words during play and routines when prompted, with occasional errors for blends/digraphs.
When prompted, says the initial sound for common objects ("ball" → /b/, "cat" → /c/) but may slip on "ship" or "train".
Plays a "find something that starts with /m/" game and finds a matching object in the room with some trial and error.
Secure
Consistently hears and states the initial sound in a wide range of words (including less familiar) and uses this awareness when choosing letters in early writing.
Quickly states initial sounds for a variety of words in conversation or book talk (e.g., "frog" starts with /f/).
During writing, chooses a plausible starting letter based on the first sound they hear (writes "b" for "bike" without being told).
Reflexive
Applies initial-sound awareness flexibly (sorting, word games, self-correcting), explains their reasoning ("it starts with /s/") and may support a peer.
Self-corrects an initial-sound answer (starts to say /p/ then changes to /b/ after repeating the word slowly).
Explains a sound match to someone else ("It starts with /s/ like 'sock'") or leads a simple sorting game by initial sounds.
