Holy Trinity High School
Chicago, IL
Catholic School Principal and Administration Jobs

Serving on the school leadership team, the Assistant Principal (AP) supports the Principal in daily operations, instructional leadership, and faculty management while upholding the mission and core values of Holy Trinity High School. The AP manages and regularly updates the academic and bell schedules within the Learning Management System, working alongside counselors to optimize student and teacher assignments. Key responsibilities include leading all logistics for standardized testing (such as the ACT and College Board AP exams) and overseeing Multi-Tiered System of Support (MTSS) programs to drive student achievement. Additionally, the AP coordinates Community Period initiatives—from advisory lesson plans to club schedules and morning announcements—and supports department chair alignment. To foster continuous professional growth, the AP works directly with the Principal to conduct classroom observations, assist teachers with instructional goals, and lead professional development. Ultimately, the AP ensures a equitable, high-expectation learning environment and assumes full administrative responsibility in the Principal’s absence.
