Once you have determined your basic eligibility, please follow the above links to more detailed information on each of the February deadline contests.
The Graduate and Undergraduate Hopwood Awards are open to all fully-enrolled University of Michigan students (with further eligibility requirements detailed at above link). Genres included in these contests are poetry, nonfiction, short fiction, novel, screenplay, and drama. These are the "big" Hopwood awards, in that there are the most number of genre categories, with the largest number of students eligible, and in that these prizes comprise the majority of the funds given each year.
There are two other contests you can submit to in February: The Arthur Miller Award and The Kasdan Scholarship in Creative Writing.
The Arthur Miller Award is open to UM students with sophomore or junior standing, and is open to submissions of drama, screenplay, fiction, or poetry. Two letters of recommendation by faculty members are required.
The Kasdan Scholarship in Creative Writing is open to all fully-enrolled University of Michigan students, and genres included are screenplays and drama. The final judge(s) for this award are at the Kasdan Company.
