Interviewer instructions
Note that this question only asks about the LAST examination the person took. Make sure the respondent considers the last one, and not a previous one (even if he/she obtained a higher score on the previous one).
Teachers grade 'A' certificate is NOT a national examination.
If the respondent took the Standard VIII examination long time ago, you should select 'standard VII', since this is the current equivalent to the former Standard VIII degree (does no longer exist now).
