How do you answer elementary school course of study on a job application?

You don't need to list your elementary school coursework on a job application. Job applications are focused on your education and experience relevant to the position you're applying for. Elementary school is far too early in your educational journey to be relevant unless you're applying for a very niche role (like an elementary school teacher, and even then, your higher education would be the focus).

Simply list your high school and any post-secondary education (college, university, vocational school) on the application. If there's a specific question about education history and it requires you to fill in all educational details from elementary school onwards, you can briefly note it (e.g., "Elementary education completed," or list the name of the school) but there's no need to detail the curriculum.
