Additionally, we identify critical and current issues related to K-12 schools and universities and provide specific examples of how school counselors and college counselors and student affairs professionals can be leaders and advocates related to these topics. Finally, we present a special focus on crisis and disaster related to leadership and advocacy in schools and universities.
