[Questions 17-19 asked of all ages.]
19c. Exam passed
These questions are to be answered for every individual. Whereas it is pointless to put all of these questions in respect of infants and very young children, a response position must be scored for every individual on questions 17 to 19.
51. Question 19C - Examinations passed
The type of examinations dealt with here are public examinations, as distinct from examinations organized within particular schools. Since you can make only one mark in the row and it is possible that the individual has passed more than one of the examinations specified, ensure that you ascertain the highest examination passed before scoring.
