Interviewer instructions
1 stands for "correct response" and signifies that the child demonstrated the skill being assessed.
0 stands for "incorect response". That is 0 means the child does not have or did not demonstrate the skill being assessed.
999 stands for "refused to respond". Refused answer is only to be used when a child literally refused to respond to a question.
When to probe: If the child does not point to a shape clearly or points to two different shapes one after the other, then you can ask them to clearly point to only one shape again AND for identifying an object in the shape of a circle, if the child identifies the shape on the card, then you can ask them to provide another example.
