School systems do not always provide a substitute therapist for short term absences. In some cases, paraprofessionals work with a child. This gives the child more opportunities to work on a particular goal, but the paraprofessional must be supervised by a certified individual. Typically, if there is a substitute therapist, it is a licensed one. If you have further questions about your district's policies, speak with your therapist directly or the district director of special education services.
