One thing to keep in mind when filing the FASFA is to file your income taxes ASAP because you have to have filed them to complete the form. And with scholarships, loans, and aide early filing is better because once they start making awards the money runs out quickly for that term. If your child has already picked a school, contact their financial aide office and ask them for any help or information that they have concerning scholarships and or work-study programs.
Major corporations, Pepsi, Coke, Tylenol,etc., had scholarships several years ago, I would google these for contact info., then request applications either by phone or e-mail. Also, the high school counselor should have a wealth of info on scholarships in your area. If they don't volunteer this info I would make an appointment to ask about scholarship opportunities.
I will say that the process can be labor intensive, so help your child with the paperwork. I don't mean writing essays for them, that should be their own work. I mean the FASFA(it involves your tax info), follow-up on dead-lines, help with the resume(format, resume grade paper), neatness of the application, all of these need attention to detail.
If you haven't noticed by now I have a passion about this subject. I was a single mother during my girls college years and we needed all of the scholarships and financial aide that we could get. They qualified for both need based and academic merit aide, they both did work-study, and had loans. They both graduated in 4 years, so I had 7 consecutive years with them in college, one year with them both in college at the same time. All of that to say, that only one year did they qualify for a Pell Grant, yet they did receive lots of financial aide. So, file the paperwork and see, don't just assume they don't qualify for help.
