(Very important)
Column 19. If the enumerated declares that they can currently read and write, the word YES should be written in this column. If they declare that they only know how to read, but not how to write, or they only write but do not read, or they declare that they do not know to read nor right, the word No will be written.
Column 20. Your attention is called to the fact that the number of years of primary instruction study (elementary and superior) that the enumerated has finished and approved in official or private schools should be written in this column. Only one of the following numbers will be written in this column: 1, 2, 3, 4, 5, or 6, since primary instruction only includes up to 6 years.
Column 21. The number of years of study finished should be written, that is, attained in a school of a higher grade than that of primary. All the years beyond primary should be added up; therefore, the primary years should not be included, since they were [P. 22] asked about this in column 20. The words "Studies finished" in column 21 means years of study attained.
Column 22. This column is earmarked for collecting data about the type and grade of instruction that the enumerated is receiving on the census date, generally, by way of assistance at a school and, in exceptional cases, by way of classes received in their home or by correspondence. Write the type or studies and the year. For example: Primary 3rd, Secondary 1st, Preparatory 2nd, Medicine 2nd, Architecture 3rd, Electronics by correspondence, etc. Be careful not to write down the type of studies or the grade of instruction received previously by the enumerated, but rather only those that they are receiving on the census date.
