How to Write Sub Plans a Substitute Can Actually Follow

Good sub plans are not the longest plans.

They are the plans a substitute can scan quickly, understand, and use while twenty or thirty students are walking into the room.

That sounds obvious, but teachers often write sub plans from their own point of view. We know what the routines mean. We know where the materials are. We know which directions need to be repeated. The substitute is seeing all of it cold.

Start with the schedule

Put the schedule near the top. Do not hide it on page four.

For elementary school, include the whole day: arrival, subjects, specials, lunch, recess, intervention blocks, and dismissal.

For middle and high school, include bell times, passing time, lunch, planning periods, and any altered schedule that day.

If the school uses rotating days, odd/even days, block schedules, or a special assembly schedule, spell out which one applies.

Tell the substitute how attendance works

“Take attendance” is not always enough.

Explain where the roster is, whether attendance is taken on paper or electronically, what to do with tardy students, and who to contact if the system is unavailable.

If you leave a seating chart, make sure a stranger can read it. The Seating Chart Maker can help you create something cleaner than a hand-drawn map only you understand.

Write the lesson as a sequence

A substitute should be able to move down the page.

Start: What should students do when they enter?
Explain: What directions does the substitute need to give?
Work: What are students completing?
Check: What should be collected, submitted, or checked?
Finish: What happens if students finish early?

This is usually more useful than a long paragraph describing your instructional intentions.

Be specific about materials

Do not write, “Pass out the worksheet.”

Write, “The worksheet is in the blue tray on the front table. Give one copy to each student.”

Do not write, “Use the slides.”

Write where the slides are, how the substitute accesses them, and what to do if they cannot.

Every place where the substitute has to guess is a place where the plan can fall apart.

Do not assume the substitute knows your subject

This matters especially in secondary classrooms.

You might get a retired chemistry teacher covering your science class. You might also get someone who has never taught your subject in their life.

If the lesson requires content expertise to explain, either provide the explanation in a form students can use independently or choose a different task.

Review work, guided notes from an accessible source, structured reading, previously taught skills, or independent practice are often safer choices than introducing a difficult new concept.

Give directions students can follow too

Your sub plan has two audiences: the adult running the room and the students doing the work.

If the student directions are vague, the substitute will spend the period answering the same question over and over.

Keep student directions short, ordered, and visible. If you tend to write long directions, the Direction Clarity Checker can help simplify them. The longer guide on giving effective directions explains why sequencing and checking understanding matter.

Explain only the routines that matter that day

You do not need to document every habit your classroom has ever had.

Focus on routines the substitute will actually need: how students enter, where they sit, how they request the bathroom, how materials are distributed, what happens during transitions, and how dismissal works.

If transitions are regularly rough even when you are present, fix the routine before relying on a substitute to manage it. The Transition Routine Builder and the article on noisy classroom transitions can help.

Leave enough work, then leave a backup

Teachers are usually better at estimating lesson time when they are in the room adjusting as they go.

A substitute cannot stretch a fifteen-minute worksheet into a fifty-minute lesson without inventing something.

Include a backup task. Make it something students already know how to do, and label it clearly.

If students finish early: complete the review activity on the back, read independently and answer the response prompt, finish missing work, or complete the extension problem set.

The exact choice depends on your class. The important part is that the substitute does not have to create the next forty minutes.

Tell the substitute what to collect

Be explicit.

Does the work go in a tray? Stay with students? Get submitted online? Need names? Need to be checked before students leave?

Also tell the substitute what does not matter. If an assignment is practice and you do not expect the substitute to grade it, say so.

Give one clear route for help

Leave the name or room number of a nearby teacher, team member, department chair, office contact, or other person the school expects substitutes to contact.

A long emergency contact directory is less useful than knowing, “If you need classroom help, call the office at extension 200,” or “Ms. Smith is next door in Room 214.”

Be careful with student-specific information

Do not turn your sub plan into a personality dossier.

Write what the substitute needs to do, not your private frustrations about individual students. If student-specific information is necessary for safety, access, accommodations, or other legitimate school responsibilities, use your district’s approved process.

Federal student-privacy rules require schools to control access to protected education records based on legitimate educational interest. The practical takeaway for a classroom teacher is simple: follow school procedures instead of inventing your own sharing system.

Use a template so you stop rewriting the same information

Your schedule, procedures, contact information, room layout, and basic routines usually stay stable.

Keep those sections in a master document and replace only the lesson-specific portion each time you are absent.

You can copy the structure on the Sub Plan Template page.

Before you send the plan, read it like a stranger

Ask yourself:

Could someone find the schedule in ten seconds?
Could they locate every material I mentioned?
Could students begin the work without me explaining it?
Is there enough work for the time available?
Is there a backup if technology fails or students finish early?
Does the substitute know what to collect and how the day ends?

If yes, you probably have enough.

You do not need to recreate yourself on paper. You need to leave a workable day.
