References from bosses or professors can demonstrate the applicant's potential, personality and past achievements. For the letters of recommendation, contact people well in advance of the due date. You should also give them your resume and all instructions for writing and mailing the letter.
Many schools list multiple options for essay topics. The essay gives the admission committee an idea of who the applicant is and why he or she is a good match for the program. Follow the essay guidelines carefully and get someone to proofread your work before submitting it.
