The framework source and supporting developmental research.
Framework source
Development Matters in the Early Years Foundation Stage (EYFS) (2012), Communication and Language: Understanding.
Object-function understanding is specified as an observable receptive-language behaviour in the EYFS progression.
Developmental research
Vygotsky, L. S. (1978). Mind in Society: The Development of Higher Psychological Processes. Harvard University Press.
Functional vocabulary and concepts are strengthened through shared activity where adults model object use and language for purposes.
Five-level rubric (detailed)ShowHide
The full progression underlying the three levels above. Used by the platform’s reasoning agent when planning activities and observations.
Not Yet
Does not show understanding of common object functions; cannot select an appropriate object for a purpose without strong cues.
When asked “What do we use to cut?” the child points to a random item or repeats the last word (“cut”).
Given a spoon, fork, and brush and asked which is for eating, the child chooses incorrectly without noticing.
Needs you to demonstrate the action (cutting, stirring, brushing) before they can pick the matching object.
Emerging
Shows partial understanding for very familiar routines (e.g., spoon for eating) but is inconsistent or needs choices/visual cues to answer.
Answers correctly for one familiar function (e.g., “spoon” for yoghurt) but not for another (e.g., “scissors” for paper).
Chooses the right object only when you narrow choices to two or when the correct object is closest/most salient.
Shows understanding by imitating the action with the object (pretends to brush) but cannot name/select it reliably on request.
Developing
Identifies the correct object for a common purpose in context (often with a small set of options), though may confuse less familiar functions.
When asked “What do we use to cut paper?” selects scissors from a small set (e.g., scissors, glue, crayon).
When asked “What do we use to drink?” selects cup from a set without needing you to mime drinking.
In play, chooses a spoon for stirring pretend soup when the items are available.
Secure
Consistently identifies objects by their use across everyday contexts and can answer simple function questions without needing options.
Answers “knife” or “scissors” appropriately to “What do we use to cut things?” depending on context.
When asked “What do we use to write?” selects a pen/pencil and can use it for the purpose.
When asked “What do we use to clean our teeth?” answers “toothbrush” and can locate it.
Reflexive
Generalises object-function knowledge to new situations, explains choices (“because it cuts”), and suggests alternatives when the usual tool is missing.
Explains a choice: “We need scissors because they cut paper” (or similar causal link).
Suggests an alternative tool when needed (e.g., “We can tear it” or “use a different knife”) if the usual object isn’t available.
In pretend play, assigns functions creatively but appropriately (e.g., uses a block as a phone and states its ‘use’ in the game).
