The Graduate Certificate in Technical Writing and Public Rhetorics is designed to be completed in slightly over a year's time currently, but starting in Fall of 2023 we aim to have the program of study done after one calendar year of study by leveraging one course in fall, one in spring, and one in each 5-week summer term.
Your graduation in the last semester of your coursework, and you may start during any given semester, so long as you meet the Graduate School's application deadlines for a given term.
Each semester you'll take a single course in the program. The goal of this workload is to allow steady progression towards your certificate without taxing you too much with coursework if you're also working full-time or have other commitments.
Each course is asynchronous, so you'll never be required to log onto your computer a specific time to receive course materials or participate in assignments. With that said, the required readings for each course will usually fall around 100 page per week, with a few exceptions here or there. You'll also be expected to complete a writing assignment in response to your readings with the content of the assignment shifting depending on the course you're in. Finally, you'll have a few major assignments staggered throughout the semester, often broken up into smaller chunks to allow for easier completion. Major deadlines almost always fall at midnight on Sunday night, allowing the entire weekend for work if necessary.
