I got an ad for this school recently. https://www.css.edu/academics/degrees-and-programs/?display=all&location=online They have a variety of online programs, including some interesting ones I haven't seen before like a Graduate Certificate in Chemistry ($650 a credit x 18 credits = $11,700) or an MBA in Rural Healthcare ($554 a credit x 36 credits = $19,944).
American College of Education has an 18 sh Certificate in Content Area Instruction in Integrated Chemistry. Southwestern College in Kansas used to have an online grad cert in Rural Health Care Administration but retired it. It's good to see another program in this important subject intersection.
