Assume the sub has your folder and nothing else
Write for someone with no login, no memory of last week, and no idea which student needs which support. Everything they need should be on paper or in a shared file the office can print: schedule, rosters, seating charts, lesson steps, routines, and contacts. If a task depends on a website, a device cart, or a password, either provide an offline alternative or leave the exact access steps.
Keep it skimmable. A substitute reads your plan in a hurry at 7:30 a.m. with students arriving. Use short numbered steps and bold the times. A wall of prose gets skipped, and the parts that get skipped are usually the ones that mattered.
The safety and roster information that cannot be missing
Lead with the non-negotiables: the daily schedule with room numbers, an accurate class roster for attendance, and the procedures for fire evacuation, lockdown, shelter, and early dismissal, including where your class goes and where the emergency roster lives. Note any student with a health plan that could require action, such as a severe allergy or a seizure protocol, and exactly who to call, without writing out private diagnoses in detail.
Include how attendance is submitted and by when, since an unrecorded absence is a safety gap, not just a paperwork one. If a student leaves your room on a schedule for a service or a check-in, list the time and the adult who comes for them so the sub is not surprised.
Lessons that hold up without you
Plan review, practice, reading, writing, or structured problem sets rather than brand-new instruction that depends on your explanation. Give the sub more than you think one day needs, plus one clearly labeled early-finisher task, so there is no dead time to fill. State the objective in one sentence so the sub can answer why are we doing this.
Spell out the mechanics: how work is distributed, where finished work goes, whether students may talk or move, and what the sub should do with students who refuse. Leave an answer key when one exists. Tell the sub which parts you want collected and left on your desk so you can see what actually happened.
Behavior and routines in writing
Substitutes lose the most time on transitions and unclear expectations. Write your entry routine, how you signal for quiet, bathroom and water rules, the noise level for each activity, and dismissal. Name two or three reliable students the sub can ask for help locating materials, though not for discipline.
Give a short behavior ladder: a calm reminder, a brief redirection, a move within the room, and then a call to the office or a neighboring teacher for anything that does not resolve. Make clear that the sub should not restrain or seclude a student and should call for trained staff if a situation escalates.
The who to call section
Put a small contact block near the top: the neighboring teacher by name and room, the grade-level lead or department chair, the front office extension, the nurse, and an administrator. Add the name of a colleague who knows your systems and has agreed to be the go-to for that day.
List what each contact is for so the sub picks correctly: the neighbor for a quick question or an extra pair of hands, the office for a student who needs to leave or a schedule problem, the nurse for anything medical, the administrator for a safety issue or a student who cannot be redirected.
Keep an emergency set that is always current
Separate from your day-to-day plans, maintain a generic emergency folder for the times you are out with no warning: two or three days of on-grade, low-prep activities that need no devices, plus current rosters, seating charts, the schedule, safety procedures, and the contact block. Refresh the rosters and schedule whenever they change, and swap the activities a couple of times a year so they still fit where the class is.
Tell the office and your go-to colleague where the folder lives, physically and digitally. A same-day absence is exactly when a good folder earns its keep, and a stale one causes its own problems.
The always-ready emergency substitute folder
- Current class rosters, seating charts, and the daily schedule with room numbers.
- Fire, lockdown, shelter, and early-dismissal procedures, including where the class goes and where the emergency roster is.
- A contact block: neighboring teacher, grade-level lead, office, nurse, administrator, and a named go-to colleague.
- Two to three days of on-grade, no-device activities with instructions and any answer keys.
- A short feedback half-sheet for the substitute to complete before leaving.
What to have the sub leave for you
Ask for a short written note at the end of the day: which classes completed which work, what did not get done, any student who was sent out or needed the office, technology or supply problems, and anything a student reported that you should follow up on. A two-minute note prevents a Monday of reconstruction.
Leave a blank feedback half-sheet with prompts so the sub does not have to invent the format. When you return, read it before you re-teach anything, adjust the next lesson to where the class actually is, and thank a sub who left the room in good shape so they will accept your room again.

Questions school staff ask about this situation
How much lesson material should I leave for one day?
Leave more than a single day appears to need, plus one labeled early-finisher task. Running short creates dead time and behavior problems, while extra work simply goes home or waits.
Should substitutes handle serious behavior incidents themselves?
No. Give a short ladder ending in a call to the office or a neighboring teacher, and state clearly that the sub should not restrain or seclude a student and should summon trained staff if a situation escalates.
What has to be in the plan no matter what?
The schedule, an accurate roster and attendance procedure, emergency procedures with your class's locations, any student health protocol with who to call, and a contact block. Lessons matter, but these prevent safety gaps.
Why keep a separate emergency folder?
Same-day absences leave no time to build plans. A generic folder with current rosters, safety procedures, contacts, and low-prep activities means a stranger can still run a safe day. Refresh it whenever rosters or schedules change.
