The doctoral curriculum has recently changed. Please be sure to follow the requirements for your catalog year.
If you entered the doctoral program in fall 2018 or later, you are required to take a set of core, analytical methods, and elective courses, write a major area paper, and complete a dissertation. If you entered the doctoral program without a previous master's degree, you are also required to complete the MA in criminology, law and society (including thesis) as an integral component of the PhD.
If you entered the doctoral program in fall 2017 or before, you are required to complete courses in three substantive fields and analytical methods, write a thesis (if required), take two comprehensive exams, and complete a dissertation.
Typically, full-time students take the required coursework during their first two years in the program, write a thesis in their second year (if required), and complete the major area paper/comprehensive exams in their third year.
