How to Maximize Your Substitute Teaching Income in 2025
Substitute teaching can be lucrative - if you know how to work the system. The difference between a sub earning $15,000/year and one earning $35,000+? Strategy.
The Income Gap
Low-earning subs (typically):
- Accept whatever jobs they can get
- Work 2-3 days per week
- Take half-days when desperate
- Miss high-paying long-term assignments
High-earning subs (typically):
- Strategic about which jobs they accept
- Work 4-5 days per week consistently
- Prioritize full-days and multi-day assignments
- Land long-term positions
The difference isn't luck. It's systems.
Strategy 1: Full Days Over Half Days
Math: A full day pays roughly 1.5-2x a half day, not 2x.
But here's the secret: Full days are easier to get consistently than trying to piece together two half-days.
Action: Set your Frontline filters to full-day only. You'll see fewer jobs, but accept more of what you see, and earn more per day worked.
Strategy 2: Build Your "Preferred Schools" List
Some schools call subs back repeatedly. Others never do.
Track this data:
- Which schools request you specifically?
- Which schools have good classroom management?
- Which schools you enjoy working at?
Focus your job hunting on these schools. You'll work more consistently and build relationships that lead to long-term assignments.
Pro tip: Sub Hero lets you filter specifically for your preferred schools. One click, and you only see jobs at schools where you're most likely to be requested again.
Strategy 3: The Multi-Day Advantage
A 5-day assignment pays 5x a single day, but requires zero additional job hunting.
The math:
- 5 separate single-day jobs = 5 job searches, 5 acceptances, 5 commutes to new schools
- 1 five-day assignment = 1 job search, 1 acceptance, same school all week
Look for: "Maternity leave," "Extended absence," "Professional development week"
These are your highest ROI opportunities.
Strategy 4: The Early Bird Actually Gets the Worm
Jobs posted between 5-7 AM have 50% less competition than jobs posted during the day.
Why? Most subs aren't checking at 5:30 AM.
Options:
- Wake up early (brutal but effective)
- Use auto-accept technology (Sub Hero Pro does this)
- Check first thing when you wake up naturally
Strategy 5: Speed Wins
When a desirable job posts, you have minutes (sometimes seconds) before it's taken.
Time to accept = Your competitiveness
Slow: Email notification (10-20 min) → Log into Frontline (2 min) → Find job (1 min) → Accept (1 min) = 14-24 minutes total
Fast: Push notification (instant) → One-click accept from phone (30 seconds) = 30 seconds total
The fastest subs get the best jobs. It's that simple.
Strategy 6: Know Your Rate and Stick to It
Calculate your effective hourly rate including:
- Drive time
- Prep time (if any)
- Job hunting time
If a half-day job 45 minutes away pays $80, but costs you 3 hours total (1.5hr driving + 4hr work + hunting time), you're making $26/hour.
A full-day close to home might pay $150 for 8 hours = $18.75/hour base, but with less overhead, you're actually making more per hour of your life.
Strategy 7: Use Dead Time Strategically
Bad: Checking Frontline during lunch, between classes, while driving
Good: Let technology monitor for you, only alert you about jobs worth interrupting your day for
This is where filtering becomes crucial. The subs making $35K+ aren't seeing every job. They're seeing the right jobs.
