* Severity of disabilities: Students with more complex needs often require more individualized attention, resulting in smaller class sizes.
* School district resources: Schools with more funding and support staff can accommodate larger classes.
* Student needs: If students require significant one-on-one support, the class size will be smaller.
* State and local regulations: There may be legal mandates or guidelines regarding maximum class sizes for special education.
Therefore, there's no single answer. A class might have as few as one or two students, or perhaps as many as eight to ten, but anything beyond that would be unusual for a class focused on such intensive needs.
