You are free to ask about scholarships at any point during your high school years.  However, most students begin asking specific questions around the end of their junior year.  Most college scholarship deadlines occur during a student's senior year.  Typically, university endowed scholarships and academic scholarships have deadline dates of around the first of December.  National scholarships have deadlines in the fall as well.  More locally based scholarships given by individuals or groups have deadlines more in the spring semester.  Keep a check on our school website and along with any university's website that you plan on attending for updated scholarship deadlines.  There are resources available on our College Planning and Resources page that give good timelines on what to do when--- applying to universities, applying for scholarships, etc.
