A regular teacher gets weeks to build a room. You get a few minutes and a folder that may or may not exist. The skills below are sorted by what they buy you, from getting cleared for the sub list to landing the long-term assignments that pay like a real job.
| Certificate | Best for | Effort | Worth it? |
|---|---|---|---|
| State substitute teaching permit or certificate | Anyone who wants to sub in a public school | An application, fingerprints and a background check, plus a short course in some states | Required almost everywhere. Get it first, since nothing else counts until you're cleared. |
| STEDI Substitute Teacher Training | New subs, especially through staffing agencies | An afternoon or two online | Some agencies and districts ask for it. Worth doing if yours does, and a decent crash course in classroom management if it doesn't. |
| CPR and First Aid (American Red Cross or American Heart Association) | Subs who take elementary, PE or special education assignments | One class, half a day | Cheap, quick and listed on plenty of sub postings. Easy yes. |
| CPI Nonviolent Crisis Intervention | Subs who want steady special education work | A day of training, usually arranged by a district | Many districts train their own staff in it. If yours offers it to subs, take it, because it opens the rooms other subs turn down. |
Substitute rules, from the degree required to how long a permit lasts, differ by state and sometimes by district, so check your state education department or the district's HR office before you pay for any course.
Substitute teacher for various schools, following lesson plans and managing classrooms.
Covered 140 day-to-day assignments across 9 schools in grades K-12, requested by name by 22 teachers, and led a 7th grade science class for a 10-week leave, entering all grades in PowerSchool.
Opening the room. If the first few minutes go well, most of the day goes well. Practice calling roll off a seating chart, putting the task on the board before the bell, and walking the rows instead of sitting at the desk.
Not for most day-to-day jobs, where you're running a plan the teacher wrote. For long-term assignments it matters a lot, because you'll be teaching new material and grading it. Pick the grade bands and subjects you can actually explain when you set up your profile.
Add special education rooms to your preferences, learn the basics of reading an IEP at a glance, and ask about crisis intervention training. Work well with the aides, since they often tell the teacher which subs to request next time.
