You can write sub plans in under 30 minutes if you stop starting from a blank page. Keep one master file in Pages or Google Docs, then copy it and fill in only what changed. This page covers what absences cost, why plans run long, and fixes that cost nothing extra.

## Quick answer

- Keep one master sub plan in Pages or Google Docs, and copy it for each absence.
- Fill in only the schedule, the activities, and the names of helpers that change.
- Write a short note for a stranger, not a lesson guide for yourself.
- Check your district's rules before you put student names in any file.
- Dictate the wordy parts with fn, then read every line before you share it.

## What writing substitute lesson plans costs you

- **Less learning on the days you are away.** In one urban US school district, each 10 days of teacher absence cut students' math achievement by 3.3 percent of a standard deviation. That comes from NBER Working Paper 13356. It is one district, so treat it as a clear signal rather than a national estimate.
- **The cost lands unevenly.** Schools in the poorest income quartile averaged nearly one extra sick day per teacher, compared with schools in the highest-income quartile. NBER Working Paper 13648 also finds that high-absence schools were much more likely to serve low-income students. Your plan does not fix that, but it can keep one day from costing more than it must.
- **Your own planning time.** I could not find a study that measures how long teachers spend on sub plans. So the 30 minute goal is a target, not a benchmark. The cost you feel is the evening spent on a plan you could have copied from a master.
- **Worry about finding cover.** In November 2023, 35 percent of US public schools were extremely concerned about obtaining substitute teachers, according to the NCES School Pulse Panel. That measures concern, not failed fills. O*NET also projects slower-than-average growth for the job from 2025 to 2035.
- **A plan the sub cannot use.** An unclear plan costs the most when the sub has no way to ask. Students lose time while the sub hunts for the worksheet, and the period drifts. No source on this page puts a number on that loss, so treat it as a practical cost.

## Why it happens

1. **The blank page.** You open an empty document, type a heading, and stop. You do not know which sections the sub needs, so the decision takes longer than the writing. A master template removes that decision before you start.
2. **Short notice.** Absences can land with little warning. If you learn about one the night before, you write the plan while tired. A plan that is mostly ready before you need it shortens that window.
3. **Routines you explain again and again.** Lunch counts, bathroom passes, and the door rule stay the same from week to week. Writing them out each time is slow and invites mistakes. Keep them in the master and change only the schedule and activities.
4. **Materials spread across places.** The worksheet is in a desk drawer, the answer key is on a home computer, and the video link sits in an old email. Each place adds a search. One shared folder cuts the hunt down to a single look.
5. **Writing for yourself, not a stranger.** You skip steps that feel obvious to you. The sub does not know them. Ask whether a new adult could follow the note without calling you. If not, add the missing line before you share the plan.

## How to fix it

- **Build one master template.** Make one file that holds every section a sub needs. Save it in Pages or Google Docs and keep it in one folder. You do the slow part once, then every later plan starts from a page that already has the routines in it.
- **Use a fill-in checklist.** Replace the essay with a list of short lines: schedule, routines, activities, early finisher, who to ask, and one behavior rule. A sub can scan a list in the first minutes of class. An essay often gets read too late to help.
- **Keep materials in one folder.** Put every worksheet, slide, and answer key in one folder, and link it from the master. Paper copies go in the binder with the plan on top. Check the folder before you leave, not after the sub calls.
- **Share with the right access.** Share the Pages file with the office for view-only access, and with a co-teacher for editing. Export a PDF when the office needs a file they can print. Click Share in the toolbar to start.
- **Dictate the wordy parts, then read them.** Hold fn and talk through the activity notes instead of typing them. Then read every name, time, and room number before the file leaves your desk. Dictation can mishear names, so check those first.
- **Keep a rough plan for bad mornings.** Store two or three activities that need no prep in the master. When the morning goes sideways, you can send a rough plan quickly and fill in the details later. A rough plan beats an empty room.

A sub plan is a short note that lets a stranger teach your class for a day. It has to answer four questions: where the sub should be, what the class does, what to do when something goes wrong, and who to ask. The routine on this page spends most of its time on the last two, because those are the parts people skip when they are tired.

## What an absence costs your students

Most of the research is about absence, not about lesson plans. In one urban US school district, each 10 days of teacher absence cut students' math achievement by 3.3 percent of a standard deviation. That result comes from NBER Working Paper 13356, which used data from that one district. It is a strong signal, but it is one district, so do not treat it as a national number.

The loss is not spread evenly. Schools in the poorest income quartile averaged nearly one extra sick day per teacher, compared with the richest quartile, according to NBER Working Paper 13648. The same paper finds that schools with persistently high absence rates were much more likely to serve low-income students. A clear plan will not fix that. It can keep one day away from costing the kids in your room more than it must.

Schools also worry about finding cover. In the NCES School Pulse Panel, collected in November 2023, 35 percent of public schools were extremely concerned about obtaining substitute teachers. It was the top concern the survey measured. That number tells you how worried schools are. It does not tell you how often a fill failed, so do not read it as a failure rate.

## What the absence costs you

The cost you feel is your own time. I could not find a study that measures how long teachers spend writing sub plans. So the 30 minute goal on this page is a target you set, not a benchmark from research. Treat it as a budget. If the plan runs past it, the template is probably missing a section.

The time usually goes to the same places. You start from a blank page. You retype the room routines you typed last term. You worry about a class you know well, handed to someone who has never met them. Each of those habits costs minutes that a saved template could have covered.

Pay is part of the picture too. O*NET, which draws on BLS wage data, lists a 2025 median of $41,670 a year, or $20.03 an hour, for short-term substitute teachers. It projects slower-than-average growth of 1% to 2% from 2025 to 2035. Plan as if the sub has never walked into your building, because they may not have.

Researchers have tested harder fixes. A randomized experiment in India, published in the American Economic Review, used daily camera monitoring and salaries tied to attendance. Teacher absence fell by 21 percentage points in the treatment schools. That is a different country and a different system, so this guide does not rely on it for US sub plans.

## Why sub plans take so long to write

Most delays come from the blank page. You open a new document, type a heading, and stop. You do not know which sections a sub needs, so you start over the next day. A fixed template removes that choice, and the time you lose to it.

- You start from a blank page every time.
- Notice is short, and the plan is due before the first bell.
- The sub does not know your room routines, so you explain them in full.
- The plan lives in several places, so you hunt for the worksheet.
- You write a lesson for yourself, not a note for a stranger.

Short notice makes it worse. If you learn about an absence the night before, you have little time to write. A plan that is mostly ready before you need it turns a late night into a quick edit.

The plan itself also needs care. Students need the schedule and the routines for lunch, passes, and the door. A sub needs to know which students need extra help, and that list needs care. Check your district's rules before you put any student name in a file.

## Fixes you can use today without buying anything

None of these fixes needs a new app or a paid tool. They use Pages or Google Docs, and a folder on your computer. Start with the template. You build it once, and every later plan starts from it.

## Build one master template you can copy

Open Pages and choose File > New. Pick a blank template or any layout you like. Press ⌘S and save it as Sub plan master. Pages starts every document from a template, so the layout you save becomes the starting point for every later absence.

In Google Docs, work in the browser. Open your master and choose File > Make a copy. Rename the copy with the date and the class. Keep the master clean, so each absence starts from the same page.

## Use a fill-in list, not an essay

The master needs these sections. Keep each one to a line or two.

1. Schedule: bell times, periods, lunch, and recess.
2. Room routines: attendance, lunch count, bathroom passes, and the door.
3. Activities: two or three tasks, each with a page number and a file link.
4. Early finishers: one quiet task that needs no prep.
5. Who to ask: the office extension, a nearby teacher, and the student helpers.
6. Behavior: the one rule that must hold, and what to do when it breaks.

Write each line as a fragment, not a full sentence. A sub does not need your teaching voice. They need to know where the pencils are and what happens after the afternoon block. Aim for one page. A longer note is harder to read in a rush.

| Section | What to write | Leave out |
| --- | --- | --- |
| Schedule | Bell times, periods, lunch, and recess | Nothing. It is the first thing a sub checks. |
| Room routines | Attendance, passes, the door, and clean-up | Routines the sub already knows from the school |
| Activities | Two or three tasks with page numbers and file links | Long lesson explanations |
| Early finishers | One quiet task that needs no prep | Extra worksheets you may not have printed |
| Who to ask | Office extension, a nearby teacher, student helpers | Personal phone numbers |
| Student notes | Only what the sub needs to keep the class safe and on track | Grades, health details, and any record your policy does not allow |

_What belongs in a sub plan, and what to leave out._

## Keep materials in one place

Many plans fall apart on the materials, not the lesson. The worksheet sits in a desk drawer. The answer key is on your home computer. Put every file the sub needs in one folder, and link that folder from the master. If the school insists on paper, staple copies to the front of the binder.

Keep a standing reserve too. Save two or three activities that need no prep, such as a reading task or a sorting game that uses materials already in the room. Use them when the planned lesson fails to load or the supplies are gone.

## Share the plan with the office and a co-teacher

Share the Pages file with a co-teacher or the front office. Click Share in the toolbar and invite them. Pages lets you choose whether each person can edit or only view the document. Give the office view-only access, and let a co-teacher edit.

For email, send one short message with the plan attached. Export the file first with File > Export To, then pick PDF or Word, depending on what the office opens. Pages can export to Word, PDF, or another file format. The [Gmail routine for teachers](https://www.lazur.app/for/teachers/gmail) covers the browser side.

## Dictate the wordy parts, then check them

Long notes are slow to type. Speaking may be faster for you, and you can test that with the [speaking vs typing test](https://www.lazur.app/tools/speaking-vs-typing-test). Hold fn in any app and talk. Lazur dictates clean, formatted text at the cursor. Read it back before you save.

Check the names, times, and room numbers first. Dictation can mishear names, times, and room numbers, and a wrong bell time causes more trouble than a missing comma. Fix those before you share the file.

## Where Lazur helps, and where it does not

Lazur does not write your class plan from nothing. It does not know your unit or your students unless you say so, or unless the page is on screen. It helps with the parts that take time: a first draft of the sub note from your bullets, dictation at the cursor, and walkthroughs for menus you use once a term.

Lazur listens and looks at your screen only while you hold the shortcut. Hold ⌥ ⌘ to ask about anything on screen, and Lazur answers out loud. Audio and the screenshot go to AI providers to answer, and they are not stored. Content is never used to train AI models.

Lazur does not click buttons, edit files, or operate other apps for you. It is not a plugin or add-in for Pages, Google Docs, or Gmail. It runs on macOS, on Apple silicon and Intel Macs. Windows is planned, not available.

You can read the [pricing page](https://www.lazur.app/pricing) before you decide, and the [download page](https://www.lazur.app/download) has the Mac app. Every fix on this page works without either one.

## Mistakes that make sub plans fail

- Writing a lesson when the sub needs logistics first. Put the schedule and routines above the lesson.
- Leaving out bell times. A sub checks these first, so put them on the first line.
- Forgetting the office. Add the extension and a room map to the note.
- Keeping the only copy on your home computer. Share it or print one.
- Putting student names in a shared file without checking district rules.
- Giving no way out. Add an early finisher task, even if you hope not to need it.

## When you cannot write a plan at all

![Person typing a short sub plan note on a laptop keyboard at a desk](https://images.lazur.app/content-images/problem/write-sub-plans-under-30-minutes/write-sub-plans-in-under-30-minutes-3-8e13d0.jpg)

Some mornings you learn about an absence with no time to spare. Call the office first, then ask a colleague to copy your master and fill in the schedule. A rough plan is still better than nothing. Rewrite it the next day, when you have time.

## Keep the master current, including for long absences

When you return, update the master before you forget what happened. Note what worked and what did not. Remove old activities and keep the routines. Each plan should start from a better master than the one before.

For a long absence, add one page for each day, with the same sections. Keep the room routines the same across pages, so the sub learns them once. Add test dates and due dates to the schedule section.

## With Lazur

Lazur is a voice assistant for the Mac that lives in the notch. Hold ⌥ ⌘ and ask; it sees your screen, answers out loud, points at buttons and walks you through apps. Hold fn to dictate. Free for 3 days, then $18/month: https://www.lazur.app/download

- “Where is Export in this Pages document?”: Lazur draws a circle and a label around the File menu so you can find Export To yourself. (Points at it)
- “Hold fn and talk through the activity notes”: Clean text lands at the cursor in Pages, Google Docs, or Gmail. You still read it before you share.
- “Ask Lazur to draft a sub note from these bullets”: Lazur drafts text from the details you give it and types it where your cursor sits. You edit it.
- “Ask Lazur to walk you through saving a copy in Pages”: Lazur guides you one click at a time and waits for each click. It does not click for you.
- “Ask Lazur where Share is in this Pages document”: Lazur draws a circle and a label around the Share button on your screen.
- “Hold ⌥ ⌘ and ask what this section is for”: Lazur answers out loud about what is on your screen, while you hold the shortcut.
- “Set a timer for 30 minutes while I write the plan”: Lazur sets timers by voice, so you can keep the writing window short.

## A plan you can start this week

- **Setup: Build the master once.** Make one Pages or Google Docs file with the sections listed above. Keep it in a folder called Sub plans. This is the only slow step, and you do it once.
- **Notice: Copy the master and fill in what changed.** In Google Docs, choose File > Make a copy. In Pages, save a copy under a new name. Fill in the schedule, the activities, and the helpers. Leave the routines alone, because the sub already has them from last time.
- **Dictate: Dictate the wordy parts.** Hold fn and talk through the activity notes. Then read the result. Check every name, time, and room number before you share it.
- **Share: Send the file, then stop editing.** Share the file with the office and a co-teacher, or export a PDF with File > Export To. Send one short message. Then leave the plan alone.
- **Return: Update the master.** Note what worked and what did not. Remove old activities and save the master, not just the copy, so the next plan starts better.

## FAQ

### How long should a sub plan take to write?

No study measures this, so 30 minutes is a goal, not a benchmark. The first version takes the longest. After that, a plan is a copy and a few edits. If you still retype the routines each time, rebuild the master.

### What should a sub plan include?

Bell times, room routines, two or three activities with page numbers and file links, an early finisher task, who to ask, and the one behavior rule that must hold. Leave out lesson explanations the sub does not need to run the activity.

### Can I write sub plans in Google Docs instead of Pages?

Yes. Keep a master in Google Docs, then choose File > Make a copy for each absence. Use File > Download when the office needs a Word or PDF copy. The same sections work in either app.

### Should I include student names in a sub plan?

Follow your district's rules on student information. Many plans only need first names and a seating chart. Leave out grades, health details, and any record your policy does not allow. If you are unsure, ask your administrator before you share the file.

### Can Lazur write the whole sub plan for me?

No. Lazur can draft text from the details you give it and type it at your cursor. It cannot know your unit, your students, or your school unless you tell it or it is on your screen. Read every line before the sub sees it.

### Does Lazur work inside Pages and Google Docs?

Lazur dictates and types at the cursor in any app, and it can point at things on screen. It is not a plugin or add-in for either app, and there is no partnership with either maker. It does not click for you.

### What if I cannot write a plan at all?

Call the office first, then ask a colleague to copy your master and fill in the schedule. A rough plan is still better than none. Rewrite it when you have time.

### Is there a version for a long-term sub?

Yes. Add a page for each day with the same sections. Keep room routines the same across pages so the sub learns them once.
