A school psychologist working in a school may be involved in all of the following EXCEPT:

The role of a school psychologist primarily focuses on the mental health and academic performance of students. This often includes conducting psychological assessments to understand each student's needs, providing behavioral interventions to address behavioral issues, and consulting with both teachers and parents to create a supportive learning environment.

However, helping a student select which high school courses to take falls outside the primary functions of a school psychologist. While they may support academic success and well-being, course selection is typically managed by academic advisors or guidance counselors who specialize in students' educational paths and curricular choices. School psychologists are more centered on the psychological aspects that affect learning and development rather than making specific decisions about course selection. Hence, this task does not align with the core responsibilities of a school psychologist.
