Hi, Fatima! Thanks for reaching out. Jenna's comments are spot on. I would add this, though - as a young person, you are working toward finding out who you are. It will take many years, so don't be alarmed if you aren't sure.
Nonetheless, you will be filtering all that you process (and report) through the filter of who you are. There is no such thing as unbiased journalism, simply because you will be acting as a gatekeeper. There is fair, accurate, and thorough journalism (at least, SOME places practice it), but no such thing as "unbiased."
Therefore, it's important - as time goes on - to determine your "voice." Now, you won't know exactly who you are when you apply to a college, but the self-awareness of saying that matriculating through a college journalism program will help you start "finding your voice" will definitely impress a recruiter. Good grades will help, also!
I would also try to show industriousness. Reporters are often going to be told, "no" and have to come up with...shall we say... unique ways of getting what they need. Examples where you wouldn't take no for an answer and kept working toward a goal - not necessarily in the storytelling arena, but something that's happened to you, anywhere - would show a recruiter you're the kind of person that belongs at that school.
Best of luck, Fatima!!
