A hospital SLP works with patients of all ages, performing evaluations, creating treatment plans, collaborating with medical professionals, and conducting swallowing tests. A school SLP works only with children, providing therapy, assessments, and collaborating with teachers and parents to develop individual education plans. Both require a master's degree and certification, but a hospital SLP may earn a higher salary. The job demand depends on location, with some areas needing more SLPs in schools and others in hospitals.
