If you're trying to find out when upper-level courses might next be offered, you can check the schedule linked on the left.

I'm currently on a 3-year phased retirement plan, so I will be teaching 18 credits this year (2019 -- 2020), and 14 credits each of the two years afterward. One of the rules for this is that I can't take on any extra assignments. So I will not be teaching summer, winter, or downtown classes, I will not be doing independent study/individualized instruction, and I will not be supervising theses.
