Instructor No-Shows: How to Build a Sub Plan That Holds

Updated September 17, 2026

When an instructor calls out the day of class, work a written sub plan: a list of cleared subs sorted by school and weekday, a lesson anyone can teach from the kit, one message that offers the class to every available sub at once, and a call to the front office before the school hears it from a parent. Build the plan before the term starts.

A text comes in at 6:47 AM. "I'm so sorry, I can't make it today. I forgot I have a test." Class starts at 3:15 PM. Twenty-two kids are enrolled. The principal went to bat for you with her PTA. Between you and a very bad afternoon is one text message and whoever you can think of before coffee.

If you've run programs in schools for more than a term, you know this morning. I know it too. At Journey to STEAM we run programs at 75+ school sites, and I've been the one texting down a list. Here's the plan that replaced the list.

What do I do when an instructor cancels the morning of class?

Work the same six steps every time, in order, and start within ten minutes of the text.

1. Reply to the instructor. "Got it, thank you for telling me early." Save the conversation about reliability for another day.
2. Open your sub list for that school and that weekday. Only names cleared for that district count.
3. Offer the class to every available sub at once. One message with the school, the time, the program and the pay. First yes gets it. Asking one person at a time burns your morning.
4. Send the sub three things: the lesson plan, the roster with how each kid goes home, and the day-of sheet with the room, the office contact and your number.
5. Call the front office before noon. Give them the sub's name and confirm the sub is cleared. Offices don't like a new adult showing up unannounced, and they are right.
6. No sub by your cutoff? Teach it yourself or cancel early. Tell the school first, then families, then put the make-up date or the credit in writing the same day.

Set the cutoff in advance. Pick a time of day and write it down, so the decision gets made with a clear head and the school hears by late morning. Nobody decides well at 2:40 PM in a parking lot.

Why do after-school instructors turn over so often?

Because of the hours. Classes run between about 2:30 and 5:00 PM, a few days a week, paid by the hour. The people who can say yes to that schedule are college students, classroom aides working toward a teaching license, recent graduates and adults between careers. They are a great fit for right now. Right now changes.

A student is available until finals. An aide is available until she gets her own classroom, which is exactly what she's working toward. Good for her, and good for kids. I still need a plan for the Thursday class she leaves behind.

The instructors are often excellent. They care about kids and they bring energy you can't teach. The schedule is what makes this job short term, and no amount of better hiring changes the schedule. So plan for turnover the way you plan for no-school days. It's on the calendar. You just don't know the date yet.

What does one missed class really cost?

Two things: the session, and some of the school's trust. The session is small. The trust is the business.

Here's the math, with example numbers. A 10-week class costs $240, so each session is worth $24 per child. Twelve kids are enrolled.

• One cancelled session, credited back: 12 x $24 = $288.
• That class runs three terms a year: 12 x $240 x 3 = $8,640 of tuition a year from one class at one school.
• Keep the school for three years: $8,640 x 3 = $25,920.

I led schools before I ran programs in them. When a principal brings you in, she has vouched for you to her families. One empty room at 3:15 PM, with kids waiting in the office, makes her wonder about next fall. A cancelled class that she heard about from you at 10 AM, with a make-up date attached, reads very differently. The $288 is the cost you can see. The $25,920 is the one you're protecting.

How do I build a sub list that works?

Turn the list of names into a table you can filter in ten seconds. A group text and a notes app hold names. They can't tell you who is cleared for this district and free on Thursdays.

Then run one check. List your classes by weekday. Next to each weekday, write the cleared subs who are free that afternoon. Any weekday with no name next to it is your exposure, and you want to find that in August.

On clearance: every adult in the room needs whatever check that district requires. Dallas ISD, for example, says a contractor with continuing duties and the opportunity for direct contact with students must be fingerprinted before beginning work, at the contractor's cost (dallasisd.org). Rules differ by state and district, so ask each one. Sending an adult who isn't cleared is how you lose a district.

How do I make a class any sub can teach?

Write the lesson so a capable adult who has never seen it can run it from the page. Three pieces make that possible.

• A one-page lesson plan with the opening activity, the build or project, the closing, and what to do when kids finish early.
• A kit packed for that session, labeled by week. The sub shouldn't be counting motors at 3:05 PM.
• The day-of sheet: room, times, office contact, roster, how each child goes home and who may pick up. I cover the day-of sheet and the dismissal plan in how to get your program into schools.

Hire for the room first and the subject second. Someone who can hold a group of eight-year-olds at 3:30 PM can learn your curriculum from a good page. There's more on hiring for mobile programs in how to start a kids enrichment business in schools.

How do I keep instructors longer?

You won't erase turnover, and you can slow it. Five practices help.

• Pay on time, every time. One rule I have is never to pay people late.
• Assign early. Tell instructors their schools and days weeks ahead, and keep the same school on the same day all term.
• Train, coach and observe. At Journey to STEAM, instructors are screened, background checked, trained, coached and observed. People stay where they're getting better at something.
• Ask about next term before this one ends. "Are you back in winter, and which days?" in week seven beats a surprise in week one.
• Make the afternoon easy. The kit is packed, the roster is right, the office expects them. An instructor's whole experience of your company is the logistics behind the class.

Where does enrops fit?

The registration side is yours in minutes: a link for each school, checkout on a phone, and a roster with grade and homeroom teacher that the sub can read. The instructor side, including invites, onboarding paperwork, availability, class matching and sub offers, is set up with our team. Instructors who receive assignments and offers don't need a login. See how it works, read enrops for after-school programs, or look at what's on each plan.

We use it at Journey to STEAM, where 95% of our school partners renew. Showing up, every week, is most of that number.

Frequently asked questions

How many subs do I need?

Enough that every weekday you run classes has at least one cleared, available sub in every district you serve. Count by weekday and district. A long list of names who are all busy on Thursdays is zero subs on Thursday.

Should I pay instructors on a W-2 or as 1099 contractors?

It depends on the facts of the job. The IRS looks at behavioral control, financial control and the type of relationship, and says a business that misclassifies a worker with no reasonable basis may be held liable for employment taxes (irs.gov). State rules differ. Read the IRS page and talk to your accountant before you post the role.

What do I tell families when a class is cancelled?

The facts, early, with the fix attached: class is cancelled today, the make-up date is this, or a credit for the session is on the way. Tell the school before you tell families.
