A grade-level chair resigns in June with two weeks' notice, and the principal who has to fill that seat by August finds out in that moment whether they spent the year building a bench or just running a staff.
I have sat with enough principals after that exact phone call to know the difference shows up fast. The ones who had already handed real responsibility to a teacher leader have a name ready before they hang up. The ones who had not spend August interviewing strangers for a role that needed someone who already knew the campus.
The bench is a decision, not an accident
Domain III, Human Capital, covers hiring, induction, evaluation, and growing the people already on your campus. It is 18 percent of the selected-response section, and the growing-your-own piece of it is the part most principals treat as something that happens on its own if you hire well. It does not. A teacher does not become a teacher leader by being good at teaching. They become one because someone handed them a specific piece of authority and let them keep it long enough to grow into it.
That handoff has to be deliberate. Pick the role before you pick the person: an instructional coach seat, a lead on a grade-level or content team, a chair of your instructional leadership team. Then pick someone whose current performance already points at that work, not someone who is simply next in line by seniority.
What an ILT is actually for
A real instructional leadership team is not a committee that reviews data once a quarter and signs off on the principal's plan. It is a group of teacher leaders who help set the instructional priorities for the building and carry them back to their own teams, so the message reaches staff from a colleague as well as from the office.
The test for whether your ILT is doing this work or just meeting: can a member of it walk into a classroom and give feedback that changes what happens the next day, on their own authority, without routing it through you first. If the answer is no, the team has a name but not the function, and the pipeline you are trying to build has nowhere to run.
Growth has to survive the first hard month
The most common way a growing-your-own plan fails is not a bad pick. It is a good pick who gets no real support once the title changes, and reverts to being a classroom teacher with an extra line on their schedule because nobody protected the time the new role needed.
Christie Ray, who has run this exact handoff from the principal's chair, is specific about the fix: build the first thirty days of the new role before you announce it, not after. A coaching cycle to run, a team to meet with weekly, a piece of data to own. A title with no calendar behind it reads as recognition, not responsibility, and the person you promoted quietly goes back to doing only their old job.
The pipeline runs lower than your building too
A principal who is serious about a bench is usually also serious about where teachers come from in the first place, and that pipeline often starts further back than the first-year classroom. Paraprofessionals who are already building toward a teaching credential, the population ParaReady supports, are frequently the staff members closest to students and most overlooked for growth, because their path to certification gets treated as someone else's program instead of part of the campus's own leadership plan. The same habit of mind, give someone real responsibility before you need them to have it, applies at every rung.
What this means if you are studying for the 268
A Domain III stem about staffing almost never hinges on who is the strongest performer in isolation. It hinges on matching the specific skill a role requires to the person already showing that skill, even when their title does not yet say so. The distractors usually reward a trait that looks like leadership, visibility, tenure, raw performance, without testing whether it is the trait the open role actually needs.
The full breakdown of all six domains and their weights, including where Domain III sits next to the rest, is on the 268 boot camp page. I wrote about the other side of this same transition, what it costs a new principal to lead people who used to be peers, in leading a team that was your peer group.
A bench you built before you needed it is the only kind that works. If you want to see how Christie Ray's own succession habits get trained step by step, the free seven-day trial opens the module built from exactly this kind of handoff, and Built To Pass carries the same discipline into every other licensure exam it covers.
