The purpose of this qualitative study was to understand how a high school counselor's perceived self-efficacy impacts high school student advising sessions as it pertains to the student's program of study and course selection. The foundation of this study was grounded in Bandura's (1986) Social Cognitive Theory (SCT). This single case study was conducted at The Red Stick School located in an urban area in the Deep South. The study included 5 high school counselors as participants who participated in virtual interviews. Explanation building was the qualitative analytical technique used to analyze the data and explain how and/or why students were advised to select certain courses and diploma pathways.
