Apply to doctoral degree programs specializing in the field of literature you wish to study. If you want a doctorate in writing, send your application to Master of Fine Arts programs that offer further study leading to a doctoral degree. Visit the department's website and research application due dates, necessary forms, required transcripts and identification documents.
Gather the necessary documents, fill out the forms and write a statement of purpose if necessary. Keep an academic writing sample on hand, since most doctoral programs in writing or literature require one. Send your applications and wait for acceptance.
Fulfill the requirements for your master's degree. Generally, your study will include writing several researched essays and a thesis if you're studying for a master's in literature; you will create several pieces of creative writing if you're working toward an MFA. During your master's study, begin developing an idea for a doctoral dissertation.
Spend three or more years earning a doctorate after acquiring your master's degree. Complete preliminary examinations in several literary subjects or composition styles. Move on to writing a dissertation, which is a book-length study of an author or literary work if you are in a literature program. Write a book-length piece of creative writing and a complementary analysis essay instead of a dissertation if you are in a writing program.
