Where Do I Start?

Jul 17, 2026

I get this question more than any other.

New principals ask it because they're scared. Scared of getting it wrong. Scared their staff won't like them. Scared they'll somehow make things worse than they found them. Most of them had no idea what they were signing up for. A principal told me recently, after a rough stretch, "I had no idea the weight you were carrying when we talked." She wasn't flattering me. She was describing just how heavy this job actually is, and how invisible that weight is from the outside. You can't understand it until you're the one carrying it.

So here's what I tell every new principal. Your first ninety days aren't about your plan. They're about the building. You have to know it before you can lead it.

RAND studied first-year principals across six major districts, including Chicago, New York, and Baltimore. What they found: there's no universal template that works the same way in every building. What predicted success had nothing to do with following a generic checklist. It came down to how good a principal was with people, whether they earned real buy-in, whether their staff actually experienced them as fair. The plan still matters. It just has to be built around this building and these people, not copied from somewhere else.

Show up ready to figure out this specific staff, fast, before you try to change anything about them.

That takes two kinds of awareness, and both take time to build.

Know yourself first. Everyone has blind spots, and a new building will find yours fast. Where do you overreact under pressure. Where do you avoid conflict. Where do you grip control when you're scared. That's not soft leadership talk. That's the job now.

Know your team second. Not just who's strong on paper, but who actually carries the culture. Who the staff already trusts. Who's been quietly holding the place together for years without a title that reflects it. That takes real time to see, and September on the calendar doesn't speed it up.

Where new principals actually trip up

The biggest hurdle I see isn't a lack of skill. It's rushing.

You walk in, you see ten things that need fixing, and you want to fix all ten in the first month. Don't. Big changes made without background knowledge, without relationships strong enough to carry them, turn good ideas into big mistakes. Your staff doesn't know yet if you keep your word. They don't know if you'll back them in a hard parent meeting. Make a change before they know it, and even your best idea comes across as a threat.

So spend real time assessing before you act. Build relationships, and not just the professional kind. With staff, with students, with parents. Know people as individuals and families, not just roles on an org chart. The teacher going through something at home. The student whose attendance dip is about more than attendance. The parent whose skepticism has nothing to do with you and everything to do with what this building put them through before you got here. None of that shows up in a data report. All of it decides whether your changes stick.

And don't play favorites. It happens without anyone meaning for it to. You'll naturally gravitate toward the staff who make your first year easier, the ones who agree with you, who laugh at your jokes, who make you feel like you're doing fine. Meanwhile, the rest of the building is watching closely to see who gets grace and who doesn't, and they'll notice faster than you think. Favoritism, even the accidental kind, will cost you the trust you haven't built yet to lose. Fair doesn't mean treating everyone the same. It means every person on staff believes you actually see them.

Does it matter if you're walking into a failing school or a thriving one?

Yes, and here's how.

You still assess and build relationships first, no matter what kind of school you're walking into. But in a struggling school, you don't get a full year to take it slow. Staff and kids need to see movement. Pick the one change that builds the most credibility the fastest, usually something that removes a daily headache for your teachers, and get that one right before you touch anything else.

A thriving school flips the risk. The systems already work, so the real mistake is changing something that's functioning just because it's not how you'd have done it. That's preference, not necessity, and it's an easy line to cross without noticing. Be especially careful about how many changes you make and how fast, if the school has already been through a lot of change recently. A staff that's been through several leaders or several reorganizations doesn't need one more disruption to prove someone new is in charge. They need someone who can tell the difference between what's broken and what's just a preference.

People aren't going to measure your success by how many changes you made in year one. They're going to measure it by whether you took the time to know them and valued what they brought to the table. That's how you build a team, not just a building. And it's what earns you the right to lead them through the hard changes later.

That's where you start.
