information and necessary recommendation materials:

• Unofficial transcript (if giving to a professor, note courses you took with him/her)

• Admissions essays/statements of purpose
• Your professional goals
• A copy of your best work (research paper, projects, publication, etc.)
• Due dates for recommendations
• Recommendation forms (if provided by the graduate program)
