Free PLC Courses with a Certificate: How to Use Them to Actually Get Hired in 2026
The honest position
A certificate from a free course does not get you a job. What gets you a job is being able to do the work in front of an interviewer, and a certificate is one line that says you tried. Used properly, a free course is the cheapest possible way to build that ability, because the material is the same as in a paid course; what you supply is the discipline and the projects.
What employers actually check
- Can you read a ladder rung and say what it does?
- Can you wire a sensor to a PLC input and explain sinking and sourcing?
- Can you find a fault from a description?
- Have you built anything: a simulated machine, a traffic light, a bottle filler, a tank level control?
- Do you know one platform well enough to open the software and start?
None of those are answered by a certificate; all of them are answered by a portfolio and a confident conversation. The interview questions in PLC SCADA interview questions are the test.
How the free catalogue is built to help
The EDWartens free courses are complete: a planned syllabus, video lessons by named creators, written notes with worked examples and practice problems, a quiz for every module and a 30-question final assessment. The certificate is optional and verifiable, with a public verification page a recruiter can check, and the reviews written by finishers are published as they were written.
A 90-day plan
Days 1 to 30: one platform, properly. Siemens TIA Portal or Allen-Bradley Studio 5000, whichever your target employers use. Every module, every quiz, every practice task, in the simulator.
Days 31 to 60: the surrounding skills. Industrial motor control for the panel side, instrumentation for the signals, industrial communication for the networks, and one HMI course such as WinCC or Ignition.
Days 61 to 90: portfolio and interviews. Three projects documented with screenshots and a short write-up each, the kind listed in portfolio projects that get interviews. Pass the finals, add the verifiable certificates to LinkedIn, and apply to the companies in top companies hiring PLC engineers.
Making a free certificate count
- Put the verification link on the CV, not just the title.
- Name the skills the certificate covers in your own words.
- Attach the project, not the certificate, to the application.
- Be ready to demonstrate any of it on a laptop in the interview.
When to pay for training
When you need hardware hours, a trainer to unblock you, a structured job pipeline and a guarantee. That is what the classroom Automation Engineer Program is for, and the free courses are the honest way to find out whether you want it before you spend anything. Many AEP students arrive having finished two or three free courses; they start ahead.
