An online trade school will not make you a licensed electrician, plumber, or HVAC tech. What it can do is teach you the theory, get you an entry-level certification like EPA 608, and make you a stronger candidate for the apprenticeship or helper job where the real training happens. For a career changer, that is often the difference between getting hired and getting ignored.
We compared online trade schools on accreditation, how directly they lead to a license or certification, price transparency, flexibility, and track record. Eight made the cut, from a free Home Depot program to a $3,480 community college certificate. This guide covers what each one costs, which trades it teaches, and who it actually fits.

How we ranked these schools
We started with the schools that other "best online trade school" guides recommend, then added options from trade associations and state workforce directories. We kept a school only if it has run for at least two years, teaches at least one skilled trade online, and has a price and recognition we could confirm on an official or government page. We left out schools that are mainly campus-based and providers that teach a single trade only, since our electrician and plumbing guides cover those.
| Criterion | Weight | What we checked |
|---|---|---|
| Accreditation and recognition | 30% | Institutional accreditation (DEAC or regional), IACET, or recognition by apprenticeship programs |
| Path to a license or certification | 25% | Does it lead to a credential employers require, such as EPA 608, or help you into an apprenticeship |
| Price transparency and value | 20% | Is the full price public, and what you get for it |
| Flexibility | 15% | Fully online and self-paced, or tied to a campus schedule |
| Track record | 10% | Years in operation and scale |
Here is how each school scored:
| School | Accreditation | License path | Price | Flexibility | Track record | Total |
|---|---|---|---|---|---|---|
| Penn Foster | 5 | 2.5 | 4.5 | 5 | 5 | 4.3 |
| PHCC Academy | 3.5 | 3.5 | 5 | 5 | 4.5 | 4.1 |
| Community college (College of DuPage) | 5 | 4 | 3.5 | 2.5 | 5 | 4.1 |
| SkillCat | 3.5 | 3 | 5 | 5 | 3 | 3.9 |
| TPC Training | 3.5 | 2.5 | 4.5 | 5 | 4.5 | 3.8 |
| ed2go | 3.5 | 3 | 3 | 5 | 4.5 | 3.6 |
| Interplay Learning | 3.5 | 2 | 4 | 5 | 3.5 | 3.5 |
| Home Depot Path to Pro | 1.5 | 2 | 5 | 5 | 4 | 3.1 |
A high score does not mean the school is right for you. A community college scores lower on flexibility because you have to show up for labs, but those labs are exactly what most online options lack. Use the decision table near the end to match a school to your situation.
Before you enroll: what an online trade school can and cannot do
Most skilled trades in the US are learned on the job. According to the Bureau of Labor Statistics, most electricians and plumbers train through a 4 or 5 year apprenticeship with about 2,000 paid hours of on-the-job training per year, and most states require a license exam at the end. No online school replaces those hours.
What online training does well depends on the trade:
| Trade | What you can do online | What still needs hands-on time |
|---|---|---|
| HVAC | Theory, troubleshooting practice, and the EPA 608 certification required to handle refrigerants | Installs, brazing, live diagnostics |
| Electrical | Theory, the National Electrical Code, exam prep | Wiring, apprenticeship hours, state license |
| Plumbing | Theory, codes, reading piping drawings | Pipe work, apprenticeship hours, state license |
| Industrial maintenance | Electrical and mechanical theory, safety | Working on real plant equipment |
HVAC is the trade where online training gets you furthest on its own, because EPA 608 is a federal certification you can study for and, with some providers, take online.
Are the trades a safe bet in the AI era?
The data is encouraging. BLS projects electrician jobs to grow 9% and plumber jobs 7% from 2025 to 2035, against a 3% average for all occupations. In May 2025, the median pay was $63,190 for electricians, $63,800 for plumbers, and $61,010 for HVAC mechanics and installers, compared with $50,980 for all workers. BLS also points to AI-driven data center demand as one reason electricians will be needed.

FAQ
Are online trade schools legit?
Some are. Look for institutional accreditation (DEAC or a regional accreditor), IACET accreditation for training providers, or recognition by apprenticeship programs. Then check whether your state accepts the program for licensing, since some trade diplomas do not meet every state's rules.
Can you learn a trade completely online?
You can learn the theory and earn some certifications online, such as EPA 608 for HVAC. You cannot finish a licensed trade like electrical or plumbing online, because states require years of supervised on-the-job hours.
What is the easiest trade to start online?
HVAC is the most online-friendly start. EPA 608 certification is federally required to work with refrigerants, and some providers let you study for it and take the exam online, which makes you easier to hire as a helper.
How much does an online trade school cost?
On this list, costs run from free (Path to Pro) and about $10 a month (SkillCat) to about $1,139 for a Penn Foster diploma and around $3,200 to $3,500 for university or community college certificates.
Can I use financial aid for an online trade school?
It depends on the school. Credit-bearing programs at accredited community colleges can qualify for federal aid, while most private online programs and ed2go certificates do not. Workforce (WIOA) funding and the GI Bill can cover some programs.
