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 a child counts the objects and provides two different responses one after the other (4, 5 for example), ask the child to select one answer only.
