Kelly: What is the student/teacher ratio in an SDC classroom in California?
Class Ratios: STUDENT/TEACHER RATIO
Special Education Law and Advocacy
Some states set ratios for districts to follow. Your state parent training & information center can provide you with info on this & other topics. http://www.parentcenterhub.org/find-your-center/
Each district sets their own unofficial ratio, since Ed Code does not state a legal threshold for the number of students in a class.
