# The Overlooked Middle Stage of School Leadership Development
Teachers who earn administrative credentials often face years waiting for principal or assistant principal positions to open. That gap between certification and appointment represents untapped potential for leadership growth, according to educators rethinking how schools develop future leaders.
The "in-between" stage, as some researchers frame it, typically spans two to five years after a teacher completes administrative licensure requirements but before securing a formal leadership role. Schools have historically treated this period as mere waiting time. New thinking suggests districts can convert it into deliberate preparation that strengthens both individual leaders and school systems.
Multiple pathways exist to develop emerging leaders during this window. Teacher-leaders can pursue instructional coaching roles, mentor newer staff, lead curriculum committees, or direct school improvement initiatives. Some districts create formal "pre-leadership" tracks where licensed teachers build administrative competencies while remaining in classroom positions. Others assign them to shadow sitting principals, lead professional development sessions, or take temporary duties in curriculum or assessment departments.
The data supports this approach. Schools that invest in multi-track leadership development report several outcomes: higher retention of licensed teachers who might otherwise leave for other districts or careers, faster onboarding when those teachers eventually move into administrative roles, and stronger school cultures when more teachers experience leadership responsibilities. The Pipeline Project at the University of Washington found that teachers who held formal leadership roles before becoming principals reported greater confidence in their first three years as administrators.
Some districts have formalized this pathway. The Chicago Public Schools system created a "Principal Resident" program where licensed teachers spend a year working alongside sitting principals while maintaining their classroom position. Los Angeles Unified School District expanded its internal leadership development program to include teachers certified but not yet appointed to administration, offering workshops, coaching, and structured practicum experiences.
The shortage of qualified principal candidates adds urgency. The Bureau of Labor Statistics reports principal positions remain difficult to fill nationwide. Many school districts struggle with principal turnover, burnout, and difficulty attracting teachers into administrative pipelines. When districts ignore the in-between years, they risk losing prepared leaders to frustration or outside opportunities.
Financial barriers complicate this work. Teachers pursuing administrative credentials invest time and money, often from their own pockets. If districts do not offer interim leadership opportunities, licensed teachers may never recoup that investment or use their new skills. Some states require continuing professional development for teachers who hold administrative licenses but do not move into those roles, creating ongoing expenses without corresponding opportunities.
The pandemic exacerbated leadership shortages. Many experienced principals retired early. Districts accelerated hiring of new administrators, but the pipeline of prepared teachers thinned. Schools that had invested in developing multiple licensed teachers during the in-between years had stronger benches to draw from.
Forward-thinking districts now view the gap between licensure and appointment not as empty space but as a strategic development stage. They assign mentors to emerging leaders, create rotational experiences across departments, fund coaching, and build visibility and networking opportunities. Teachers benefit from compensation adjustments or stipends for leadership work. Schools benefit from distributed leadership capacity that improves operations and school climate.
This approach requires districts to think differently about career pathways. Rather than viewing administration as a single-step transition from classroom to principal's office, progressive districts create multiple rungs on the leadership ladder. The in-between years become formative, not futile.
