Reading Child Data

What do you already know?

SPEAK Have a go — no notes, no pressure. Think of a small child you've known: a sibling, cousin, neighbour, or a child in a film. How did they talk? Try to remember two or three real things a two- or three-year-old actually says. What sounds different from adult speech?
SPEAK Now a prediction: a three-year-old says "I goed to the park." Nobody ever taught them the word "goed" — so where did it come from? Say your best theory out loud.
Today: how Paper 2 works and how to read child-language transcripts, so you can open any past paper and know exactly what you are looking at.

Between the ages of one and five, children pull off the greatest learning feat any human ever manages — and they do it without lessons, without grammar books, and mostly without correction. Paper 2 hands you a recording of a real child mid-feat and asks: what exactly is this child doing, and how do we know?

Every "strange" thing a child says is a clue. Your job in this exam is to read the clues like a linguist.

The exam, in numbers

1
question — that's all
45
marks for that one essay
75
minutes to plan and write

The question always follows the same shape:

Analyse how [the child]'s language at this stage of development allows them to [FOCUS — e.g. engage and interact with a parent].
In your response you should consider any relevant language frameworks, levels and theories as appropriate.

The words in the FOCUS slot change from paper to paper — and they are the most important words on the page. Every paragraph you write must connect back to them.

Where the 45 marks come from

MarksWhat earns them (in plain words)
30Analysing the data with correct terminology, well-chosen quotes, and theories applied to the evidence — all in clear, well-organised academic writing.
15Linking language to context: who is talking, where, about what, with what shared knowledge — and how that shapes the meaning that gets made.

The Golden Rule: development, not deficit

Examiners state it directly: candidates must not treat the child's language as faulty. A child who says "it yummy" is not failing at English — they are mid-way through building it. Writing about children as if they are broken adults is called the deficit model, and it caps your marks.

Fix the sentences

Each sentence below breaks the Golden Rule. Say aloud how you would rephrase it in proper exam voice, then reveal one strong version.

1. "The child gets the word 'dog' wrong and calls every animal a dog."

"The child overextends the label 'dog' to other four-legged animals, a typical stage in early semantic development."

2. "She makes a mistake with the verb and says 'runned'."

"She produces the non-standard past tense 'runned', an overgeneralisation of the -ed rule which shows she is applying grammatical patterns productively."

3. "His pronunciation is bad — he can't say 'spoon' properly."

"His pronunciation of 'spoon' as /pu:n/ shows consonant cluster reduction, a predictable simplification at this stage of phonological development."
SPEAK In one sentence, explain the pattern you just used three times: what did every strong version do that the weak version didn't?
Each strong version (1) names the feature with a precise term, (2) treats it as a normal stage, and (3) says what it shows about development — description upgraded to analysis.

The transcript key

Exam transcripts use a standard set of symbols. You must read them automatically — they are evidence, not decoration.

SymbolMeaningWhy it matters
(.)micro pausehesitation, thinking, holding a turn
(2)pause in secondsa long pause is data — someone is processing or waiting
/pu:n/phonemic transcription — the sounds actually producedthe gap between the target word and the produced sounds is analysable gold
boldemphasis / stressshows what a speaker is highlighting
{indecipherable}speech that couldn't be transcribeda reminder this is real, messy, recorded speech
?rising intonation of a questionlets you count who asks the questions — a key interaction clue

The slashes are the ones to master. Ordinary spelling tells you what the child meant; the slashes tell you what came out of their mouth. Every source booklet includes a phonemic reference chart — you look sounds up, you don't memorise the chart.

Decode practice

A child aged 2;9 (two years, nine months) says each of these. Read the phonemic form aloud, work out the target word from the context, then reveal.

1. At the zoo, pointing: "look (.) a /ˈefənt/"

Target: elephant. The unstressed first syllable /e/ survives but /l/ is dropped — long words keep their rhythm and lose their quiet parts.

2. Asking for a drink: "more /dʒu:/ peas"

Target: juice — and "peas" is please with the /pl/ cluster simplified. Two words, two features.

3. At bathtime: "where /bʌbəz/ gone?"

Target: bubbles. Also notice the missing little verb: "where bubbles gone" has no have — remember that shape; it gets a name in Lesson 3.
SPEAK Which of the three was hardest to decode, and what strategy did you use to crack it?

Your first transcript

Maya is 2 years and 10 months old. She is having breakfast at home with her father. Read it twice: once for the story, once for the clues.

F: what's in your bowl this morning?
M: nana /ˈnænə/
F: banana? (.) lovely (.) is it a big banana?
M: it big (.) a big big nana
F: it's a very big banana (.) what will we do after breakfast?
M: er (2) park?
F: we could go to the park (.) what will you go on at the park?
M: the /wɪŋ/ (.) me go on the /wɪŋ/
F: you'll go on the swing (.) you love the swing don't you
M: yeah (.) high high

Clue hunt

Find one example of each, say it aloud, then check:

A. A place where Maya's sounds simplify a word.

/ˈnænə/ for banana (the unstressed first syllable is dropped) and /wɪŋ/ for swing (the /sw/ cluster is reduced). Either counts.

B. A place where a little grammar word is missing.

"it big" — the verb is is absent. Also "me go on the swing" — me where adults use I, and no will.

C. A place where the father repeats Maya's meaning back in full adult grammar.

"it's a very big banana" and "you'll go on the swing" — he returns her sentences with the missing pieces installed, without ever saying "wrong". This move gets a name in Lesson 5.

D. Count the questions. Who asks them all — and what does that tell you?

The father asks every question (four of them). He is powering the conversation, giving Maya repeated invitations to talk. She supplies the content; he supplies the engine.

From noticing to exam voice

Noticing a clue is step one. The exam rewards a very specific sentence shape. Compare:

Just noticingExam voice
"Maya says 'wing' instead of 'swing'.""Maya's /wɪŋ/ for 'swing' shows consonant cluster reduction, typical of her stage of phonological development — yet her father understands instantly, so communication succeeds."

See the ingredients? quote the data name the feature call it typical of the stage link to the conversation

Which sentence would an examiner reward most?

Now you build one

Write one exam-voice sentence about "me go on the /wɪŋ/". Use all four ingredients, then compare.

"Maya's 'me go on the /wɪŋ/' combines a non-standard pronoun, an absent auxiliary verb and a reduced consonant cluster — three typical features of her stage — yet the utterance succeeds completely as a plan for the day, which her father confirms with 'you'll go on the swing'."
SPEAK Read your sentence aloud. Which of the four ingredients was hardest to include?

From memory

Everything closed except this page — answer from memory, out loud first, then reveal.

1. How many questions, marks and minutes in Paper 2?

One question, 45 marks, 75 minutes.

2. What is the "deficit model", and why must you avoid it?

Treating the child's language as faulty or broken. Examiners reward the opposite framing: every feature is a normal, analysable stage of development.

3. What do /slashes/ show in a transcript — and what is the analysable "gap"?

The sounds the child actually produced. The gap between the target word and the produced form is where phonological analysis happens.

4. Name the four ingredients of an exam-voice sentence.

Quote the data · name the feature · frame it as typical of the stage · link it to the conversation (and, from Lesson 4 onwards, to theory).

Three-minute challenge

Start the timer, look back at the Maya transcript once, then close your eyes to the page and speak for the full time: describe everything you found — features, quotes, the father's role — as if explaining the transcript to someone who has never seen it.

REFLECT We said you'd be able to open any past paper and know what you're looking at. Can you? What helped most today — the symbol table, the Maya transcript, or building the exam-voice sentence? Why that one?
I can read a child-language transcript, decode its symbols, and describe what I find without the deficit model.
