Column 13: Educational Attainment. Information should be collected on the last grade or the most advanced year of studies that the person has passed, not the grade that they are currently in or studying, nor the grade that they've been in or studied, but without having passed. Record, for example: 2nd [year of] primary [school]; 5th [year of] secondary [school]; 3rd [year of] law school, etc.

In the case of a person who has studied and passed courses abroad, record the equivalent grade or year in the corresponding Chilean educational system.

For those who have never attended school, record: "O". [Translator's note: this appears to be the letter "O" and not the number "0".]
