Why do so few psychologists offer clinical assessments

Just something that I have noticed lately. I live in a medium-sized city on the east coast, and yet I still feel as though there are fewer than 10 psychologists in the city who offer psychodiagnostic or psychoeducation assessments. Granted, this is amongst private practice practitioners, as many of those employed in hospitals are probably neuropsychologists, or focus on specific medical populations. Why do so many not wish to offer assessments? Is it risk of litigation or going to court?
