Final answer:
School counseling has expanded to include leadership, advocacy, and collaboration, providing a broader scope of support for students beyond just vocational guidance.
Step-by-step explanation:
School counseling has evolved from its early focus on vocational guidance to become more comprehensive. This expansion has included aspects such as leadership, advocacy, and collaboration. Schools now integrate these broader roles into their counseling programs, focusing on enhancing the social, emotional, and educational development of students. While individual long-term therapy (more related to clinical psychology), registration and attendance monitoring, and psychological testing and diagnosis are all important elements within the education system, they are not specifically the expanded roles that modern comprehensive school counseling covers.
