“…Four categories were created: (1) preservice teachers were working toward teacher licensure and had no years of experience independently in a classroom as, (2) novice teachers had 1 year of experience (Barrett et al, 2002), (3) early career teachers were those with 2–4 years of experience, and (4) master teachers had five or more years of experience (Rivkin et al, 2005). Although some researchers define “master” based on specific criteria (e.g., award recipients and in leadership positions; Hite & Milbourne, 2022), others use definitions that are less concrete (e.g., transitioning into leadership roles as they develop an expertise in content, schooling, educational policy, and educational practice; Shulman, 1987; Toh & Tsoi, 2008). Our designation of “master” is a practical one, based on years of experience because we assume that teachers who have been teaching six or more years are likely no longer on probationary status (Thomsen, 2014), have had the opportunity to mentor an early career teachery/have hosted a student teacher, and may have taken or/ considered taking leadership roles at their schools.…”
