Resume

Hi all,

Can I include my position with the Public Defender's Office on my resume even though it was around my senior year of high school? I like putting this position down because it shows interest in the law at a relatively early time (and affirms my narrative that I've been interested in pursuing this field for a long time) but I understand that high school-related experience is really not something we should be putting down.

Also, are resume's for law schools really only supposed to be one page in length?

Thank you all in advance!
