Formatting is important for student essays for several reasons:
1) Good formatting gives the reader a good first impression of the essay and presents it in a professional, academic style that does not distract from the content.
2) Standard academic formatting makes the essay predictable and easier to read, respecting the reader's time by efficiently delivering the content without surprises.
3) Students need to learn to conform their essays to various formatting requirements and preferences of different readers, such as professors or scholarship applications, in order to demonstrate their ability to follow instructions. Ignoring formatting can negatively impact a student's grade.
