This tells us the number of key words that a child has to understand in a sentence to carry out an instruction. It involves the child making a choice between objects, places etc.
In order to be sure that there is true understanding at any of the stages, there must be a choice for the underlined words.
For example:
1 word level Where’s the car?
Equipment needed: car, brush
2 word level Give the ball to dolly.
Equipment needed: ball, car, teddy, dolly
3 word level Put the spoon in the bag.
Equipment needed: shoe, spoon, bag, box, in/on/under
As language develops, it is normal for a child’s understanding to be at a higher level than their spoken language e.g. a child may understand a 3 word level instruction, but may only be joining 2 words expressively e.g. ‘daddy car’
