The general range across states
At the low end, some states require nothing more than a high school diploma or equivalent plus a background check to receive a substitute credential or permit. At the higher end, other states require some amount of college coursework — commonly cited tiers include 60 semester credit hours, or an associate's degree, sometimes with a minimum GPA requirement — before the state will issue a substitute authorization.
This spread exists because substitute teaching sits at the intersection of two different state interests: keeping classrooms staffed (which pushes toward a lower bar, especially during teacher shortages) and ensuring some baseline instructional competency (which pushes toward requiring coursework). Different states have struck that balance differently, and some have adjusted their requirements over time in response to substitute shortages.
Examples of the range (verify current rules directly with your state)
Texas has historically used a tiered system through regional education service centers, with options ranging from a diploma/GED up through 60 or more college credit hours depending on the specific district or service center's requirements. New Jersey has required a minimum of 60 semester hours at a regionally accredited institution for its substitute credential in past guidance.
Because these thresholds are set by state regulation and can change — particularly during periods of substitute shortage, when some states have temporarily lowered requirements — treat any specific number you read (including the examples above) as a starting point to verify against your own state department of education's current substitute-credential page, not as something to rely on without checking.
What districts commonly add on top of the state minimum
Even where the state sets a low floor, individual districts frequently add their own requirements: a background check and fingerprinting (nearly universal), an orientation or short training session, proof of a negative TB test or other health screening in some states, and sometimes a basic skills or literacy assessment. A district can require more than the state minimum, but generally cannot require less.
If you're substitute teaching across multiple districts within the same state — a common practice for people trying to maximize available work — check each district's specific onboarding requirements separately, since the state credential is usually the floor, not a universal pass into every district's classrooms without further paperwork.
How to actually find your state's current requirement
Search '[your state] substitute teacher certificate' or '[your state] substitute teacher permit' directly on your state department of education's website rather than relying on general aggregator articles, which can be outdated or imprecise about a specific state's current tiered requirements. State requirements do change, sometimes with little public notice, particularly around minimum credit-hour thresholds.
If you're close to a state border and considering substituting in a neighboring state, do not assume your existing credential transfers — most states treat substitute credentials as separate from full teaching licenses, and reciprocity rules that apply to certified teachers moving between states generally do not apply the same way to substitute-only credentials.
Steps to check before applying to substitute in your state
- Search your state department of education's site directly for the current substitute credential/permit requirement, rather than an aggregator article.
- Confirm whether the requirement is tiered (e.g., diploma vs. some college credit vs. associate's degree) and which tier applies to the type of assignments you want.
- Check whether your state's requirement has changed recently due to a substitute shortage — some states have temporarily lowered thresholds.
- Contact each district you want to work in separately to confirm their specific onboarding steps (background check, orientation, health screening) beyond the state credential.
- If moving between states, verify whether your credential transfers — most substitute credentials do not carry the same reciprocity as full teaching licenses.

Questions school staff ask about this situation
Do I need a college degree to substitute teach?
It depends entirely on your state. Some states require only a high school diploma or equivalent plus a background check; others require some college coursework, commonly cited around 60 credit hours, or an associate's degree.
Does a substitute credential transfer if I move to a different state?
Generally not automatically. Substitute credentials are typically state-specific and usually do not carry the same reciprocity protections that apply to full teaching licenses moving between states.
Can a district require more than my state's minimum substitute requirement?
Yes. States set a floor, but individual districts commonly add their own requirements on top of it, such as an orientation session, additional background screening, or a basic skills assessment.
Where can I find my state's exact current substitute teaching requirement?
Search your state department of education's own website directly for its substitute teacher certificate or permit page — this is more reliable than general articles, since requirements can change.
