Sub Plans: How to Write Substitute Teacher Plans That Actually Work

Most teachers treat substitute teacher plans as a necessary evil — something to dash off at 5am when illness strikes, hoping for the best. The result is days of lost instructional time, students who've watched movies and completed word searches, and a class that needs re-settling when you return.

It doesn't have to be this way. A well-designed substitute plan is actually a model of clear, self-contained lesson design — and the habits that make good sub plans make your regular teaching more effective too.

What Makes a Sub Plan Fail

The most common sub plan failures:

Too dependent on teacher expertise. The plan says "continue the unit on fractions" with no context. The substitute doesn't know where the class is, what they've covered, or what the next step is. They improvise — usually badly.

Activities with no accountability. Worksheets with no collection process, discussions with no structure, independent reading with no product — these invite students to socialize rather than learn. Students know when the real teacher isn't there.

No classroom management guidance. The substitute doesn't know your procedures, your signals, which students need support, or what consequences look like in your classroom. Without this, management deteriorates.

Vague timing. "Do the reading then discuss" — for how long? In what structure? When does one end and the other begin?

Writing a Sub Plan That Works

Think of your sub plan as instructions for a smart but uninformed adult. They can follow clear directions. They can't read between the lines.

Write a class overview section: Grade, subject, number of students, typical behavior, two or three things that help the day go well, two or three things to watch for.

Name each phase of the day explicitly: "9:00-9:15: Morning meeting. Students sit in a circle on the rug. Go around the circle: each student shares one sentence about something they're looking forward to this week. That's it — no elaboration required."

Give page numbers, not concepts: Don't say "continue the science unit." Say "Students will read pages 45-48 in the blue science textbook, which is on each desk. After reading, they'll complete the questions on the attached handout."

Build in accountability: Materials turned in at the end of class, a specific product students complete, a sign-out sheet for bathroom breaks. Accountability isn't punitive — it's the structure that keeps students on task when the regular classroom norms aren't fully activated.

List procedures explicitly: How students get to lunch, what the dismissal routine is, what to do if a student needs the nurse, where the emergency information is kept.

A Standard Sub Plan Structure

A sub plan for one school day typically includes:

1. Welcome note to the sub (who you are, brief class description, contact info if needed)
2. Daily schedule with exact times
3. Lesson plans for each subject block — detailed enough that a stranger can run them
4. Key student information (any students with medical needs, IEPs, or specific behavioral plans)
5. Classroom management information (signals, routines, consequence structure)
6. Materials location (where to find everything referenced in the lesson)
7. Emergency procedures

Keep a sub plan binder that stays current. Update it monthly. Having to write a sub plan from scratch at 5am when you're sick is the worst version of this problem.

The Best Sub Activities

Some lesson types work much better than others when a substitute is running them:

Best: Independent reading with a written response, structured note-taking from a text, defined review activities with clear completion criteria, science labs or activities that are entirely self-contained and don't require teacher explanation.

Okay with good directions: Structured group work with clear roles and a defined product, independent math practice on previously introduced concepts.

Avoid: New conceptual content introduction (students won't learn it from a substitute), open-ended discussions without a product, any activity that requires the substitute to understand the curriculum deeply.

The goal is to protect instructional time — not to advance the unit (leave that for when you're there), but to ensure students spend the day in purposeful, structured learning rather than in chaos.
