How to become a substitute teacher:
requirements, reality, and what comes next.Substitute teaching is one of the fastest ways to get into an education career — in many states, you can be in a classroom within 60 days of deciding to pursue it. But the experience varies enormously by district, grade level, and how you approach the role. This guide covers what's actually required, what the job is actually like, and how to use it strategically if teaching long-term is your goal.

The step-by-step path
What the real process looks like, in order.
Understand your state's requirements
Requirements to substitute teach vary more by state than almost any other education role. Some states require a bachelor's degree and a substitute teaching license. Others require only 60 college credits. A handful allow high school graduates with a clean background to substitute in emergency situations. Know exactly what your state requires before spending time or money on anything else.
- Search '[your state] substitute teacher requirements 2024' — state education department websites have the official requirements
- Determine if your state requires a substitute teaching license/permit (most do) or just a background check
- Find out if there's a minimum credit hour requirement and whether your existing education meets it
- Check if your state requires a separate license for long-term substituting (30+ consecutive days) — many states do
Complete required credentials and background check
The most common requirements are: a bachelor's degree (or 60 credit hours in some states), a clean background check (fingerprinting required in most states), and a substitute teaching permit or emergency license. The background check and fingerprinting process is often the longest step — plan for 2–6 weeks for clearance in most states.
- Submit your fingerprinting application as early as possible — this is typically the slowest part of the process
- Apply for your state substitute teaching permit/license if required — this often requires official transcripts
- Complete any required orientation or training your district mandates (some districts have online modules)
- Gather documentation you'll need: official transcripts, government-issued ID, Social Security number
Apply to districts and get on the sub list
Once you have your credentials, you apply directly to school districts (not the state). Most districts now use online substitute management platforms like Frontline (formerly Aesop), Kelly Educational Staffing, or SubFinder to post and fill assignments. You'll register on the platform, set your availability, and accept jobs as they come available — usually posted the night before or early morning.
- Apply to multiple districts in your area simultaneously — more districts means more assignment opportunities
- Complete each district's onboarding: tax forms, emergency contacts, direct deposit for pay
- Set up your Frontline or SubFinder account and learn how the system works before your first assignment
- Indicate which schools and grade levels you prefer — you'll get better assignments as you build a track record
Build a reputation that gets you requested
The difference between a substitute teacher who's constantly busy and one who struggles to get assignments is reputation. Schools keep internal lists of subs they'll request back. Be professional, follow lesson plans, maintain classroom management, and leave thorough notes for the teacher you're covering. Within 3 months of consistent good work, specific teachers and schools will start requesting you directly.
- Arrive 10–15 minutes early to every assignment — this alone puts you ahead of most substitutes
- Follow the teacher's lesson plan faithfully, even if you disagree with their approach
- Leave detailed notes for the returning teacher: what you covered, which students were helpful, any issues
- Learn students' names quickly — substitutes who make the effort to use names have dramatically fewer classroom management problems
- Treat every assignment as an audition for being hired full-time if that's your goal
Use subbing strategically if teaching full-time is your goal
Substitute teaching is an excellent entry point to a full-time teaching career. Most teachers are hired from within the district's substitute pool — principals hire people they've seen work. If you're pursuing a teaching credential alongside substituting, the classroom experience is directly applicable and often can satisfy student teaching requirements in some states.
- Tell principals and teachers directly that you're interested in full-time opportunities — they often know about openings before they're posted
- Request long-term substitute assignments specifically — these are the most visible to administrators and most like full-time teaching
- Pursue your teaching credential concurrently if full-time teaching is your goal — many programs accommodate working students
- Build genuine relationships with the teachers you cover — they're your references and referral sources

What most guides won't tell you
The honest realities of this career path.
Classroom management is the hardest part and no one prepares you for it. Students test substitutes in ways they don't test their regular teacher. The first few assignments can be genuinely difficult. Having clear expectations from the moment you walk in — not aggressive, but unambiguous — is the most important skill.
The income is not enough to live on in most markets if you're subbing every available day. At $120–$150/day and 180 school days in a year (minus holidays, days you don't get called, days schools close), realistic annual income is $15,000–$28,000 for most substitutes. Long-term assignments and working in multiple districts help.
Cancellations happen frequently. Substitutes who budget based on full-capacity availability are often disappointed. Schools cancel assignments for unexpected reasons, and some mornings you accept a job only to be told at 7 AM you're not needed.
The experience is highly variable by grade level. Elementary substitutes deal with different challenges than high school substitutes. Most new subs should start with their natural comfort zone and branch out as they build confidence.
Is this career right for you?
Great fit if…
- You genuinely like working with young people and find their energy engaging rather than draining
- You want flexible scheduling — substitute teaching is one of the few jobs where you can largely choose when you work
- You're building toward a full-time teaching career and want direct classroom experience
- You have existing income from another source and want a meaningful, people-centered way to supplement it
May not be right if…
- You need consistent, predictable income — substitute income varies significantly week to week
- You struggle with authority challenges or find classroom management stressful — this is the defining daily challenge
- You expect to be treated as a full professional in the same way a licensed teacher is — substitute status comes with limited autonomy and resources
