Questions 20, 21 and 22 - For persons who attend school

Consider as attending the school not only those who take regular courses, but also those attending Pre-school, Adult literacy course, General Education (attending class on the radio or television), College entrance exam course, Master's degree or Doctor's degree.
Also consider as attending school persons who, are duly registered but, on the date of reference, are temporarily unable to attend for reasons of illness, etc.
Do not consider as attending school persons who, on the date of the Census, are attending only short courses for professional specialization or cultural extension, such as sewing, dancing, typing, etc.

Question 20 - Grade currently attended

For persons who attend courses in grades/years, mark the grade/year they attend.
If the course attended is not organized by year, but according to a credit system, academic periods, semesters, phases, modules, etc., these credits, periods, etc. should be converted into the traditional grades or years. Therefore, the 5th period of credits at a university is usually equivalent to the 3rd year; each phase or division of schooling generally corresponds to a grade or year in regular courses.
For persons who attend non-graded courses or who do not attend school. Box 0 - None - will be marked.
