No. Professionals who are obligated to provide services as mandated on IEPs (including special education teachers, general education teachers in ICT classes, related service providers, and paraprofessionals) must serve each student as mandated and may not be assigned to other duties (such as exam scoring or coverage/proctoring for other classes) that would prevent them from doing so, except in extraordinary circumstances. Substitute coverage for both general and special education teachers must be arranged when being asked to score exams.
