I'm an office administrator at a 350-person manufacturing company. I handle all supplier orders—hardware, software, and training—roughly $80,000 annually across fourteen vendors. I report to both operations and finance.
In early 2023, three of our maintenance technicians asked for PLC programming courses. I didn't brush it off. Our production line runs on Allen-Bradley PLCs—a CompactLogix on the main assembly, a Micro850 on packaging, and a ControlLogix rack we installed in 2019. We also still have an old MicroLogix 1100 with the red housing sitting in the corner as a backup—that thing has outlasted two of our newer units. If a technician can't troubleshoot a fault, we're paying an external contractor $180–$250 an hour while the line sits idle.
But I had $12,000 in a training budget that also covers forklift certification and electrical safety recertification. So I sat down with our operations manager and compared two paths: formal Allen-Bradley training through Rockwell Automation or an authorized distributor, versus self-study using online courses, manuals, and forums.
We spent about six weeks comparing them side by side. I've now watched the results for a year and a half. Here's what I wish I'd known from the start.
The comparison framework
We compared both options across four practical dimensions: direct cost versus downtime cost, time-to-competence, knowledge retention, and real-world troubleshooting capability. I chose those four because—frankly—they're the ones I could explain to our finance director without getting a blank stare.
Dimension 1: Direct cost vs. hidden cost
Formal Allen-Bradley training through Rockwell or a distributor runs in the ballpark of $1,800–$2,500 per technician for a multi-day course. I remember quoting somewhere around $2,200, maybe $2,400. I'd have to pull the invoice. (Should mention: that doesn't include travel if you're going to one of their regional training centers—we budgeted an extra $600 per person for hotel and meals on the longer courses.)
Self-study looks cheaper. Much cheaper. A Udemy course on PLC programming costs $20–$150. Rockwell publishes extensive documentation, and technicians can access the Knowledgebase with a TechConnect contract—which we already had. So on paper, self-study is a no-brainer for a budget-conscious administrator like me.
But here's the catch: self-study has a hidden cost that doesn't show up on a purchase order. When a technician learns by trial and error on a live production line, mistakes aren't hypothetical. In 2023, a misconfigured timer on a packaging machine cost us about $3,800 in lost production. That's nearly two formal training seat fees.
So which one actually costs more? Formal training, if you only count the invoice. Self-study, if you count the mistakes. That's the bottom line.
Dimension 2: Time-to-competence
Formal training has a fixed timeline. A technician goes away for four days, comes back with a specific skill set—usuallly enough to handle basic logic modifications independently.
Self-study has no schedule. One of our techs took seven or eight months before he considered a colleague "independent" at program modifications. Another faster learner got there in maybe four months. Wide range, which makes it hard to plan.
Here's where the comparison gets interesting: if your team already has basic PLC experience, self-study is actually faster for a narrow, specific task. If they're starting from scratch, formal training wins on time. By a lot.
Dimension 3: Knowledge retention
I assumed formal training would mean better retention. That turned out to be only partially true.
What I heard from technicians: the formal course gave them structure and a chance to ask questions in real time. But here's the thing—when I tested them a month after the course, the self-study techs who solved problems on actual equipment retained it just as well. Maybe better. Because they'd already burned their hands on it.
Formal training gives self-study people a head start. But the head start shrinks fast if they don't keep practicing.
Dimension 4: Real-world troubleshooting
This is where the rubber met the road for me.
During a vendor review in late 2023, one of our technicians asked—genuinely confused—"what is AGM on a battery charger?" Our power backup supplier had sent a new spec sheet, and nobody knew what the AGM setting meant. AGM stands for Absorbed Glass Mat—a type of lead-acid battery construction commonly used in backup power systems. The self-study track had left gaps like this: nobody thought to Google something they didn't know they didn't know.
The formal Allen-Bradley course covered power supply and battery backup fundamentals in the first two hours. Basic stuff. But that's exactly the kind of context a self-taught technician misses.
Second example: when our main packaging line threw a weird I/O fault, the formally trained technician was the only one who could explain the relationship between wire shielding, grounding requirements, and point-level failures. The self-study tech eventually figured it out—six hours later.
What I'd recommend, based on what I've seen
If your team already has basic PLC experience and needs quick upskilling on a specific task, self-study plus Rockwell's documentation can go a long way. Pair them with someone who can answer targeted questions—ask a mentor before you're stuck.
If someone on your team is starting from zero, formal Allen-Bradley training is the safer baseline. Yes, it's more expensive. But it reduces blind spots and teaches them to ask better questions.
My actual solution—the one that worked best for my budget—was a hybrid. Send one technician to formal training as a foundation, then have that person become the in-house resource for everyone else's self-study questions. We spread one seat fee ($2,400ish) across a three-person team. Better outcome than either sending all three to self-study or doing nothing and hoping for the best.
One more thing worth flagging: if you're evaluating training vendors—whether Rockwell or third-party—per FTC advertising guidelines, they should be able to substantiate claims about what their course achieves. If a vendor says "our course makes your team experts in three months," ask questions. Request the syllabus. An informed customer asks better questions and makes faster decisions. That applies to training procurement too.
Closing thought
It took me about eighteen months and a $3,800 mistake to understand that the right training mix depends heavily on where your team already stands. The question isn't "which is cheaper" or "which is faster." The question is "what's the gap, and which path closes that gap fastest?"
When a technician asks what AGM means on a battery charger, you know the gap is wider than you thought. That's when structured training earns its invoice.
