Plan for a substitute as a likely case. The Education Week Research Center's analysis of the federal Civil Rights Data Collection found that 28 percent of teachers in that federal data, more than 901,500 people, were absent more than 10 school days. The count covers sick or personal leave and leaves out professional development and field trips.

What a sub can open also varies. One district's substitute information page says substitutes may have an account with limited access, and that a teacher may arrange temporary access. Write the plan for the weakest case: a person with a paper page and a browser.

Here are great tips for you in this scenario:

1. Preview the clip to the last second

Watch the whole clip yourself, from the first frame to the last, before you write the plan around it. A teacher must always preview the audio/video before presenting it to students, and previewing can also show that only part of the clip is worth using. When you won't be in the room, that matters more. A sub can't know that the first minute is a slow intro or that a sponsor message follows. Write down what you found and what to skip.

2. Give each part a job, a time and a stop

Build the lesson around what students should do or discuss before, during, and after watching it, and write a time beside each part. A substitute who has never seen your class has no feel for how long a discussion runs. A plain schedule keeps the period from drifting. Say how the clip connects to what the class is studying, too, so it reads as part of the lesson and not as filler.

3. Tell the substitute how to work the equipment

Write out the steps for every device the substitute will touch, from the power button to the input. Directions for electronic devices belong in the substitute folder because every classroom's setup differs, and a substitute who has never been in yours can't work it out by guessing.

Name the small things as well. Say where the projector remote is kept, which input to select, and whether the sound comes through the speakers or the screen. If a neighboring teacher or a tech contact knows the room's equipment, list the name and the room number.

4. Make sure the substitute can open the clip

Test the link the way a stranger would meet it: in a private window, on the school's Wi-Fi, on a device like the one in the room. Your own laptop tells you little. You may be logged in to a school account or a learning platform that opens the page for you and stops a stranger at a sign-in screen. Plan for the ordinary kind of failure, because technological issues can and do happen.

The device itself may need a login too. If your school gives subs a shared login, say where to find it, with the front office as one option, and don't copy it onto a plan that sits on a desk in front of students. Never write your own password on the plan. Without a way in, the sub is stuck at the start of class with a locked screen and a room of students waiting.

5. Check the sound and the captions

Play a few seconds of the clip with the sound set the way the sub will hear it, through the room's speakers rather than your headphones. Say where the volume control is, too, because a quiet or muted clip is easy to mistake for a broken one. If the class will lean on captions, read along with the stretch you plan to use, using the same link the sub will open. As of October 22, 2026, YouTube's automatic captions are generated by machine learning algorithms, so the quality of the captions may vary. A wrong word in a key term is easier to flag on the plan than to correct in a lesson you aren't there to run.

6. Use a page that starts and stops where you want

Put the clip on a dedicated page, so the sub gets a start and a stop instead of a time to remember. SafeShare creates a dedicated page for a YouTube or Vimeo video that focuses on the video content, rather than sending viewers to the original platform. Set a custom start time and an optional end time, and viewers see only that segment.

Check a few things before you rely on it. Make the page while signed in to a free account, which keeps links active, because as of October 22, 2026, anonymous links may expire within a few hours. Videos whose owner has turned off embedding, and age-restricted, region-blocked or private videos, will not play. Firewalls on school networks may block certain domains, so run the connection test on the school's Wi-Fi to see whether it can reach the services the page depends on.

Then open the finished page before you leave. It can still show some of the video's own information, such as its title and uploader. Unlisted means anyone with the link can open it, which is what a sub with no login needs. Because anyone with the link can read them, leave student medical or discipline details out of the link, the title and the description.

7. Leave a backup that needs no device

Leave one activity that needs no screen, in case the link, the room's equipment or the network fails. A backup like this helps the substitute make adjustments when needed, and the best one can start without setup, such as a short reading with questions or a discussion prompt on the same topic.

Say when to switch, for example if the clip still isn't playing after the first few minutes of class. That way the sub doesn't spend the period troubleshooting.

8. Ask the substitute to note what happened

Add a form for the sub to leave a status report, even if it is only a few lines at the bottom of the plan. Ask whether the clip played, where the class stopped, and what got in the way. Add a line for any questions students asked that you'd want to answer yourself.

The note takes the sub a minute and spares you from piecing the day together from what students tell you. It also shows whether your link and your equipment directions worked, so you can fix them before the next absence.
