If not applicable, what should you enter in the institution name field?

When faced with the question of what to enter in the institution name field when it is not applicable, "Self-study" is the most appropriate choice. This option effectively communicates that the learning has been conducted independently rather than through a formal institution. It suggests a personal initiative in education, which can often be relevant when assessing qualifications or competencies acquired outside traditional educational settings.

In contrast, other options such as 'My school' implies the presence of a formalized school which doesn't fit the criteria of not applicable. 'None' might suggest there was no educational component at all, which could be misleading when you have engaged in learning. Similarly, 'Individual' doesn't convey the nature of the learning experience effectively; it could also imply that there's no structured learning involved. Therefore, 'Self-study' correctly signifies an independent educational effort.
