KPU has a procedure for students who are experiencing significant and disruptive life events to withdraw from classes with a W on their transcript past the usual withdrawal deadline. Every one of these situations is unique, so the procedure is slightly flexible, especially the documentation requirements.
In some cases, this is a very obvious event like an accident or sudden death in the family, but many others like the breakdown of a marriage or a mental health issue may not have an obvious starting point. You should approach your instructors to seek modifications or accommodations such as Incomplete contracts before applying for compassionate withdrawal. Meeting with a KPU counselor is also usually wise. You have until 20 days after marks come out to apply.
