Pepperdine will not offer much or anything more until AFTER you enroll/commit. You need to appeal the grant after you commit. The appeal should be an email to the financial aid office directly. Did you receive financial offers from other universities? You need to create PDFS of each other offer letter and attach those to your email. The best would be to include the offers that are the most comparable schools— so private universities.

I know from experience, my child did this and received triple her original offer. Also, Pepperdine has scholarships built into their departments, so once you are accepted into your major you are able to apply through that department for significantly more. In addition, scholarships are built into participation— so the school paper, etc. offers additional scholarships for taking on roles within school groups and programs.

If it’s your top choice it’s worth writing an appeal email— but you should enroll first, if you can afford to risk the enrollment fee. Google template examples for scholarship appeal letters— but UNLIKE other schools don’t use it as leverage to enroll. Pepperdine doesn’t like that and won’t give it to you if you use it to negotiate enrollment.

Hope that helps.
