What programs are you considering? What state/area? What's your last 60 credits GPA? Most programs care about your last 60. And what is your major GPA?
I live in MD and it is highly competitive in the DMV, a 3.2 GPA on an application would probably not be considered for interview unless there were standout points. Depending on your area, programs can be more competitive or less.
I'll be attending Gallaudet U as a hearing student. Contrary to belief, some programs in the graduate school don't require ASL fluency just the willingness to learn ASL and Deaf culture. Funding is not advertised when you apply, but it is there.
I also received a half graduate assistantship to another program, that gave half-tuition and a stipend.
The variation could depend on region.
Funding availability really varies in School Psych programs. I only applied to DC/Maryland school programs, but from what I've seen a lot of programs don't offer funding with the acceptance letter. And if you do receive funding it could be anything from a small scholarship to a full GAship. Like a lot of Masters programs in other fields, it is often expected you secure your own funding.
I received a full-tuition scholarship to the program I am going to, so my yearly cost is only about $500.
