Supervision is a critical opportunity for a clinical psychology trainee to receive feedback to develop their skills. The chapter begins by describing ways to make the most of this opportunity. Practical steps are outlined that include, goal setting for supervision sessions, planning agendas, ways to learn from sessions recordings, and accounting for supervisory outcomes and activities, and how to challenge yourself to advance beyond the familiar. The chapter also critiques recent developments in “reflective practitioner” approaches to supervision and outlines practical steps to remain evidence-based by using data-driven reflective practice. The chapter concludes with a discussion about how to begin to learn supervisory skills as the clinical psychology trainee anticipates one day moving into a supervisory role.
