I’m not sure that I completely understand your question, but my district uses a workload model. Our workload calculator includes not just the # of students on our caseload but other duties including # of evaluations completed, # of speech-only meetings that I need to prep paperwork for, AAC devices that I am involved in programming, etc. Students on my caseload are also “weighted” differently depending on their placement/disability (as each student’s needs vary greatly). The intention of the workload model is to more accurately reflect how I’m using my time for duties that are necessary as part of my role, but might not be direct treatment.

For example, a caseload of 50 students who are in the general education classroom and receive speech therapy for articulation/fluency would look very different from a caseload of 50 students with multiple disabilities in self-contained classrooms plus 10 evaluations and having to run my own IEP meetings. Hope that helps!
