What building leaders notice first — and what to do about it

By the time the fire drills are behind you, and the master schedule has settled, most principals already have a read on how the year is forming. Not from a dashboard, but from hallways, cafeterias, and the quiet asides teachers make in passing. The first six weeks of school are the richest, least-used data window a building leader gets. Referral numbers won’t show up until October. An attendance pattern won’t trigger a letter until it has been repeated for weeks. But the early signs are already there, in shifts that are easy to miss when a building leader is focused on schedules, staffing, and the hundred other things that come with opening a school year.

None of what follows is a diagnosis, and no single instance on this list should set off alarms on its own. The value is in the pattern, not the moment — and the advantage building leaders have in September is proximity: you are close enough to the ground to see a pattern form before it shows up anywhere else.

Here are five worth watching for now.

1. The Monday Pattern

Watch for: A student who wasn’t an attendance concern last year suddenly missing specific days — often Mondays, the day after a break, or the morning of a test — or arriving late in a way that repeats rather than a one-off.

Why it matters: Anxiety-driven school avoidance often looks identical to ordinary truancy on an attendance report. The difference matters enormously for how a building responds, but it only shows up when someone looks at the pattern instead of the single absence.

What to do: Don’t wait for a pattern to become a truancy letter. Flag it to your counselor or student support team as soon as it repeats — ideally before it hits your district’s automatic attendance-letter threshold.

2. Quiet Withdrawal

Watch for: The student who used to eat with a group now eating alone. A club or team roster short one name, with no explanation. A friend group that’s noticeably missing someone it used to include.

Why it matters: Social withdrawal is one of the most consistent early indicators that a student is struggling, and it’s also one of the easiest to miss — it doesn’t generate a referral, a grade, or a nurse visit. It just gets quieter.

What to do: A brief, low-key check-in from a trusted adult — not a formal meeting — is often enough to surface what’s going on, or to signal that someone noticed.

3. A Drop in Effort or Grades with No Clear Cause

Watch for: Missing assignments piling up, or a visible drop in the quality of work, in a student who was previously on track and hasn’t had a change in course load or schedule.

Why it matters: Academic disengagement is frequently a symptom, not the problem itself. By the time it shows up on a progress report, it’s often already been building for weeks.

What to do: Ask whether the drop is isolated to one class or shows up everywhere. A single-class drop points toward that classroom or teacher relationship; a drop across every class points somewhere else.

4. Physical Complaints That Don’t Add Up

Watch for: Repeated nurse visits for headaches, stomachaches, or fatigue with no clear medical explanation — especially when they cluster around a specific class period, day, or person.

Why it matters: Somatic complaints are frequently how younger students, in particular, express anxiety they don’t yet have the language to name directly.

What to do: Compare nurse-visit logs against the schedule. A visit that reliably lands before third period, or before a particular class, is telling you something the student may not be able to say out loud yet.

5. A Shift in Behavior — In Either Direction

Watch for: A normally easygoing student becoming irritable or reactive. Just as tellingly, a normally talkative or high-energy student going unusually quiet and compliant. An uptick in minor disciplinary referrals for a student with no prior pattern.

Why it matters: Behavior is communication, and it doesn’t always communicate in the direction people expect. Building leaders are often trained to notice acting out; the quiet version is just as significant and far more likely to go unnoticed.

What to do: Note the change itself in the student, not just the incident that brought it to your attention. A single detention is a data point. A student who has never had one and suddenly has three in two weeks is a pattern.

What Building Leaders Can Do with This List

A list like this is only useful if it turns into action inside a building, not just awareness. Three things help:

• Give teachers a low-friction way to flag a pattern, not just an incident. Most referral systems are built for behavior events. Few are built for “this is the third time this month I’ve noticed something off with this student,” which is exactly the signal that matters most in the first six weeks.
• Treat two or three data points together as more urgent than any one of them alone. A student showing up on this list in one category is worth a note. A student showing up in two is worth a conversation.
• Make sure your team knows what happens after a flag is raised. A reporting pathway that dead-ends at “noted” doesn’t help anyone. Building leaders don’t have to be the ones who resolve what’s underneath a red flag — but they do need a clear, fast route to the people who can.

That last point is where most buildings feel the gap most acutely. Counselors and school psychologists are stretched thin nationally, and a principal noticing five students showing early signs in September doesn’t automatically translate into five students getting support. Closing that gap is what an embedded clinical partnership is designed to do — licensed clinicians working inside the building, integrated with the school’s existing MTSS framework, so a flagged pattern has somewhere real to go.

In independent research conducted by the Yale Child Study Center (Amanda M. Dettmer, PhD) evaluating Effective School Solutions’ high-fidelity clinical programs, 95% of participating students were prevented from therapeutic out-of-district placement, with 35% fewer disciplinary incidents, 31% fewer absences, and 56% fewer hospital stays. Those numbers describe exactly what this list is meant to catch early — the difference between a pattern addressed in September and one discovered in November.
