Warning: these figures indicate the number of cases found in the data file. They cannot be interpreted as summary statistics of the population of interest.
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: When the child doesn't clearly point to one item, you can prompt the child once asking them to point to one item clearly.
Do not probe if the child clearly points to one item, even if the response is incorrect.
