Yes, as a Commerce graduate, you can pursue a career in Speech Pathology, but it will require a shift in academic focus. Speech Pathology, or Speech-Language Pathology (SLP), is a specialized field that deals with diagnosing and treating communication disorders, which typically requires a background in science or healthcare.
To transition, you may need to take prerequisite courses in areas such as Biology, Psychology, or Communication Sciences. After that, you can enroll in a master's program in Speech-Language Pathology, which is the standard requirement to practice in most countries.
