The Short Answer: No Public Pass Rate Exists
If you searched for the FESTO-L2-PLC2 pass rate hoping for a tidy percentage, here is the honest answer: neither Festo nor the National Coalition of Certification Centers (NC3) publishes one. No public pass rate was verified for Level 2: Advanced Mechatronics PLC Technology II: Allen Bradley or Siemens, and this article will not invent one.
That may feel unsatisfying, but it is more useful than a made-up number. Sites that quote a precise pass percentage for this credential are either guessing, borrowing a figure from a different certification that shares similar naming, or extrapolating from a small sample. A pass rate you cannot trace to a source cannot help you plan your preparation.
What you can do is understand the structure of the assessment, the rules that govern attempts, and the skills the training actually builds. Those factors tell you far more about your personal odds than an anonymous statistic would. This guide walks through what the data does and does not show, then turns that into a practical readiness plan.
What Is Actually Verified About This Credential
Before discussing outcomes, it helps to pin down exactly what this credential is. The governing body is Festo, and the administrator is the National Coalition of Certification Centers (NC3). The current issuer describes this same PLC Technology II (Allen Bradley or Siemens) scope as Applied PLC, Level 2. It is not the separate Level 3 Advanced PLC credential, and mixing the two is a common source of confusion when people compare difficulty or results.
The training builds on PLC fundamentals and contains 6 units and 5 labs. If you are new to the naming, our explainers on what FESTO-L2-PLC2 is and what the identifier stands for cover the background, and the certification overview places it within the wider Festo and NC3 program.
| Item | What is verified |
|---|---|
| Governing body | Festo |
| Administrator | National Coalition of Certification Centers (NC3) |
| Training structure | 6 units and 5 labs, building on PLC fundamentals |
| Assessment parts | Written and practical competency |
| Minimum result for students | At least 70%, plus all hands-on labs |
| Student certification charge | USD 0 under NC3 Participation Benefits |
| Public pass rate | Not verified |
| Public question count and time limit | Not verified |
Notice what is missing from the bottom of that table. There is no verified question count, no verified written-exam time limit, no verified practical-assessment duration, and no verified pass rate. Anyone quoting those figures as fact is working from outside the sources that govern this credential.
How the Two-Part Assessment Works
NC3's certification process requires both written and practical competency. That dual structure is the single most important thing to understand about your odds, because it changes what "passing" means compared with a one-sitting multiple-choice test.
The written component
Written questions run through NC3Certs.com. They are randomized and automatically graded. Randomization means two candidates in the same classroom are unlikely to see identical question sets in identical order, so memorizing a fixed sequence is not a viable strategy. Automatic grading means the result is objective and quick, with no instructor discretion at this stage.
The practical component
Practical assessments take place in a verified facility or lab. An independent proctor checks identity and stays throughout. Because this credential covers PLC programming and troubleshooting on Allen Bradley or Siemens platforms, the practical side is where hands-on fluency matters: you are expected to work with real equipment rather than describe it.
The eligibility conditions
Under the NC3 End User License Agreement, students need training from an actively certified instructor, the required lab equipment, completion of all hands-on labs, and at least 70%. Instructors face a higher bar, needing 80% and recertification every three years. Students do not need to recertify. If you want the full eligibility picture, see our guide to FESTO-L2-PLC2 requirements and our breakdown of the passing score.
What Really Shapes Your Odds of Passing
Without a published pass rate, the useful question becomes: which factors realistically move your chances? Based on how the credential is built, several stand out.
Your foundation in PLC fundamentals
Because the training builds on PLC fundamentals, candidates who arrive with shaky basics, such as reading a ladder rung, understanding scan cycles, or distinguishing inputs from outputs, spend their limited lab time catching up instead of advancing. The advanced material assumes the fundamentals are already automatic.
Access to equipment
Students need the required lab equipment. Practice on real hardware, or a faithful simulator of the platform you will be assessed on, is a major differentiator. Reading about forcing an output is different from doing it under time pressure while a proctor watches.
Platform choice: Allen Bradley or Siemens
The scope covers Allen Bradley or Siemens. Your training center's platform determines your software environment, addressing conventions, and instruction set. Preparing on a platform different from the one in your lab is a quiet way to lose points on familiar-looking tasks.
Instructor quality
Since training must come from an actively certified instructor, and instructors themselves must hold an 80% result and recertify every three years, the instructor is part of the quality chain. Ask your program how current its instructor certification is and how many lab hours are guaranteed.
Key Takeaway
Treat the missing pass rate as a signal to focus on controllables: strong fundamentals, real hands-on time on your assessed platform, and complete lab coverage. Those drive your result far more than any aggregate statistic would.
Domain-by-Domain Readiness Check
The issuer lists seven unweighted preparation topics. It is important to be clear about their status: no formal weighted exam blueprint was verified, so these headings do not establish exhaustive exam coverage or an official exam-domain count. They are best read as the curriculum themes you should be comfortable with. For deeper treatment, see our exam domains guide.
Domain 1: Ladder Logic Programming
The core language skill. You should be able to build, read, and debug rungs without hesitation.
- Contacts, coils, and rung structure
- Latching and interlocking patterns
- Translating a written process description into logic
Domain 2: Basic PLC Operations and Programming Functions
The functional building blocks that go beyond simple contacts and coils.
- Timers and counters and how their presets and accumulators behave
- Data handling and comparison functions
- How the controller executes its program cycle
Domain 3: Uploading and Downloading PLC Programs
Moving programs between the programming device and the controller safely.
- Online versus offline states and what each allows
- Backing up before overwriting
- Recognizing mismatches between project and controller
Domain 4: Program Modifications and Testing
Changing working logic without breaking it, then proving the change works.
- Making controlled edits and documenting them
- Using test modes and forcing with caution
- Verifying behavior against the intended sequence
Domain 5: Human Machine Interface (HMI) Design
Connecting operators to the process through a clear interface.
- Screens, tags, and the link between HMI and PLC data
- Buttons, indicators, and alarm presentation
- Designing for clarity and safe operator action
Domain 6: Basic Networking Concepts for Industrial Systems
How controllers, HMIs, and devices communicate.
- Addressing and communication setup at a basic level
- Recognizing when a communication fault, not logic, is the problem
Domain 7: System Troubleshooting and Fault Diagnosis
Where everything converges. Candidates must isolate faults methodically.
- Distinguishing field wiring, I/O, program, and communication faults
- Using online monitoring to trace a rung that will not energize
- A repeatable diagnostic sequence rather than guesswork
A useful self-check: for each domain, ask whether you could complete a hands-on task on real equipment, not just explain it. If the honest answer is "I could explain it," that domain needs more lab time.
Retest Rules and What They Imply
The retake policy is one of the few areas with concrete, verifiable numbers, and it shapes how you should think about risk. Retesting is limited to three administrations within a year. The policy also specifies a 100-day wait before additional attempts may be awarded. The public wording does not define the interval between each permitted attempt, so do not assume a particular gap; confirm it with your testing center.
| Rule | Detail | Practical meaning |
|---|---|---|
| Attempt cap | Three administrations within a year | Attempts are finite, so avoid sitting before you are ready |
| Extended wait | 100 days before additional attempts may be awarded | A failed final attempt can mean a long delay |
| Interval between attempts | Not defined in public wording | Ask your center for its specific scheduling rules |
The implication is straightforward. Because attempts are limited, treating the first sitting as a casual "see what it looks like" try is a poor use of a scarce resource. Our exam dates and scheduling guide covers how to plan timing around these limits.
How to Spot Unreliable Pass-Rate Claims
Because no verified pass rate exists, it is worth knowing how to evaluate the claims you will encounter.
- Precise percentages with no source. If a figure is not tied to Festo or NC3 reporting, treat it as unverified.
- Numbers borrowed from other credentials. Several certifications use similar naming, and statistics sometimes migrate between them. The PMMI PLCs 2 certification, for example, is a separate program with its own syllabus that does not define Festo PLC II coverage.
- Estimated duration mistaken for exam length. An older Festo Level 1/2 PLC sheet lists 16 hours, but that figure is an estimated course duration, not written-exam or practical-assessment timing.
- Level confusion. Results or difficulty claims for the separate Level 3 Advanced PLC credential do not apply here.
A Domain-Ordered Prep Sequence
Since the real risk is under-preparing on hands-on skills, order your study by dependency: later domains rely on earlier ones, and troubleshooting rewards everything beneath it. Pair this with the full study guide for deeper technique.
Logic foundations
- Domain 1: build ladder rungs from written process descriptions
- Domain 2: practice timers, counters, and comparison functions
Program handling
- Domain 3: rehearse upload and download on your assessed platform
- Domain 4: make and test controlled program modifications
Interface and communication
- Domain 5: build a simple HMI screen tied to PLC tags
- Domain 6: review basic industrial networking concepts
Integration and troubleshooting
- Domain 7: work through fault scenarios, isolating wiring, I/O, logic, and communication causes
- Take timed written practice and rehearse practical tasks end to end
Schedule troubleshooting last on purpose. It draws on every earlier domain, so practicing it early, before your logic and program-handling skills are solid, produces frustration rather than learning. For a rapid refresher near test day, the cheat sheet condenses the key points, and the practice test site offers written-style questions to check your recall.
Costs and the career picture
The student certification charge is USD 0 under NC3 Participation Benefits, but tuition, institutional access, and instructor-training charges are separate, so check the certification cost breakdown before budgeting. On the career side, the BLS Occupational Outlook Handbook reports a USD 73,900 May 2025 median annual wage for electro-mechanical and mechatronics technologists and technicians. That is an occupational benchmark and does not measure a salary premium from this specific credential. Our salary guide and jobs overview unpack this further, and the ROI analysis weighs the decision.
Frequently Asked Questions
