A school counselor is someone who helps students with their academic, social and emotional needs. They help students understand their emotions and give them advice and guidance. They also help with academic problems, like figuring out which classes to take and how to get better grades. They also help students plan for their future after high school, like which college to apply to or what types of jobs they might want. School counselors are there to provide support and guidance so that students can reach their full potential.
