Many schools also have a policy that they don't not extend tuition waivers for employee families for a certain amount of time. My mother worked at a major university in Boston and was not allowed for the first five years. I wasn't able to go there, but my sister attended there for near free (still have some fees and books).

You may want to look into the Yellow Ribbon program. Different schools have voluntarily extended different offers for veterans, active duty , and families. https://www.benefits.va.gov/GIBILL/yellow_ribbon/yrp_list_2018.asp

Enough time has passed, but can you share the result. Did you manage to find out something? We have a similar situation and now my wife is doing introductory tasks, one of which turned out to be writing an essay on psychology. We started to research the information and found this source https://sunnypapers.com/paper-samples/psychology/ which had samples of argumentative, persuasive and narrative essays. Thanks to the information received, we were able to better research the topic, and write our own paper.
