The purpose of school counseling at a high school is to provide guidance, support, and assistance to students as they navigate the challenges of adolescence and prepare for their future. High school counselors play a critical role in helping students to develop their academic/occupational, personal, and social skills, and in providing them with the resources they need to succeed in school and life.

School counselors work with students one-on-one or in groups to address a variety of issues, including academic performance, social and emotional well-being, career exploration, college planning, and personal growth. They may also provide support to students who are experiencing personal or family problems, such as stress, anxiety, depression, or relationship issues.

In addition to working with students, high school counselors collaborate with teachers, parents, and other school staff to create a supportive and inclusive learning environment. They may also provide professional development and training to teachers and staff on topics such as mental health, cultural sensitivity, and conflict resolution. 

Overall, the goal of school counseling at a high school is to promote the academic, personal, and social success of all students through a comprehensive school counseling curriculum, and to help them develop the skills and knowledge they need to achieve their goals and reach their full potential.
