I live in California.
I’d like to know how much researchers and therapists who work with children with autism make per year if they have a BA degree. A masters degree? A doctorate?
If there’s any other information needed to answer this question please let me know.
I’m just looking for a basic pay scale per year.

The US Bureau of Labor Statistics is a good place to scope out pay ranges for the variety of jobs that fall in this field.
As an example, with special education teachers, the median pay is roughly $44,000 a year, with the high end being in the range of $70,000 a year.
Different fields will show a large disparity in pay. From those doing neurological studies, to those that provide social services. Look around at my source and I’m sure you’ll find the information you seek.
