(Take my review with a grain of salt. I am a fat cis able-bodied white woman, so I cannot speak for anyone's experience but I will share my thoughts on what I can.)
De Anza is an excellent college on a beautiful campus. The campus itself is relatively flat, with most classes located in one story buildings. The few buildings that do have stairs also have elevators. There are a few ramps located throughout the campus, and all buildings are wheelchair accessible.
There are a few issues one encounters as a fat person, which can also be issues for those who use wheelchairs. For instance, many of the classrooms are equipped with chairs that are attached to desks. This makes it a tight squeeze for anyone with a belly, and few classrooms are equipped with wheelchair or ADA desks. Those that do have these desks rarely have more than one per classroom, and they are oftentimes situated in the back of the room. Many of the bathroom stalls are tight squeezes as well.
Trans inclusivity is ok at De Anza. There is a name change form that is somewhat easy to access from the webpage. Students are currently pushing for there to be a preferred pronouns column on the roll call sheet. There are a few single stall bathrooms around campus. Additionally, if you stop by the Jean Miller Resource Room there is a key to a private bathroom that is for staff and students who need it. In the spring there is a Queer Studies class, and events building up to Pride, including the Queer And Now conference, a Lavender Graduation, and Pride Ball. That said, visibility is still an issue, but the current interim president wants to help, and has specifically stated as such, so I am hopeful.
There are a number of resources on campus dedicated to POC, including Men Of Color, Umoja, HEFAS(Higher Education For AB 540 Students). Because the campus is located on Ohlone land, many of the events start with a welcoming ceremony in which there is an acknowledgment and an appreciation of the land usage. There are various events for heritage specific graduations, Black Graduation(on Juneteenth), Latinx Graduation, etc. There are a number of ethnic studies classes as well, but not enough.
Overall, I think De Anza does a fairly good job, but it is not perfect, when it comes to inclusivity.
