Kaiako making effective use of assessment to foster oral language growth will regularly: 

• consider children’s capabilities in languages across all their environments, for example, in English, home languages, and community languages 
• engage with whānau as experts on their child’s interests and their language capabilities at home and in other settings 
• use assessment information to help select effective teaching strategies that match the needs and interests of a child, group of children, or the service as a whole 
• use assessment for informing conversations about language learning with children, whānau and families, other kaiako, and external support agencies 
• consider what assessments tell you about progression over time and how you can support children to get to the next step. 

In the 'Stepping stones in oral language’ part of Te kōrerorero, Talking together you will find lists of the broad progressions seen in the development of language and communication for infants, toddlers, and young children in English. Use the descriptors within each of these to inform your observations and gather evidence about progression over time. Descriptors are grouped under the following topics: 

• sounds – order of speech sound development and developing phonemic awareness 
• words – expected word bank and types of words used at different stages 
• sentences – word order, word endings, and sentence structure 
• stories – enjoyment and participation through to creating their own stories 
• social interaction – attention, responses, and conversational strategies. 

All language and communication relies on skill development in: 

• receptive language – the ability to hear, process, and understand information 
• expressive language – the ability to respond and express meaning with sounds, words, gestures, or signing. 

Children’s receptive language is usually ahead of their ability to express and respond. This is the reason why it is important to address both aspects within assessments. For example, a child described as "having no English" may not speak but still have a good understanding of the language. 

When observing language and communication progressions, consider: 

• How well do they understand what is being expressed to them? How do you know that? 
• Does a bilingual or multilingual child demonstrate receptive language capabilities in their home language/s? 
• Can they follow one or two simple directions – an indication of their receptive language capabilities? 
• If they are not using words, do they use gestures to respond and express themselves? 
• In what situations and with which people do they use or not use expressive language?
