Note(s): The variable “Experience in years” includes assistant principal roles held prior to enrollment in the principal training program. While assistant principals are not required to attend the program, they may do so based on school organizers’ request. 75% of the participants reported 4 years or less of leadership experience (median: 3 years), with only 7.1% reporting 7–10 years of experience
