C-208 Passing Score 2026: Exactly What You Need to Pass

What the Passing-Score Question Really Asks

Candidates searching for the Programmable Controller Troubleshooting 1 (C-208) passing score usually want one number: the percentage that separates a pass from a fail. The honest answer is more nuanced than most exam sites admit. C-208 is a Smart Automation Certification Alliance (SACA) micro-credential assessment, and the public record does not show a single, national, universally applied cut score for it.

What the public record does show is useful. There is a published seven-objective skill standard, a documented 70% Silver threshold at one college testing center, and clear differences between the written Silver test and the hands-on Gold assessment. This article separates what is verified from what is not, so you can plan your preparation without relying on a rumor.

If you are still orienting yourself, start with What Is C-208? and the C-208 Exam Domains guide, then come back here for the scoring picture.

What the Skill Standard Does and Does Not Publish

The authoritative scope source for C-208 is the SACA document Certified Industry 4.0 Automation Specialist I - Core Micro-Credential Skill Standards, Version 1.0, specifically printed pages 22-23. Those pages reproduce competency objectives 208.1 through 208.7. A current provider, College of the Sequoias, reproduces the same seven objectives in its SACA Gold Assessment preparation curriculum, which corroborates the scope.

Here is what that standard is, and what it is not:

• It is a list of competency objectives. Seven of them, covering PLC troubleshooting and sequence programming.
• It is not a weighted blueprint. No percentage is assigned to any objective, so you cannot calculate that one topic is worth a fixed share of your score.
• It does not state a cut score. The retrieved standard describes skills, not a pass mark.
• It is not presented as a verified 2026 revision. The filename references 2019 and the document is Version 1.0, so treat it as the best available scope reference rather than a dated exam-version guarantee.

Also note that no exact current C-208 written question count or exam timer was verified. Any site quoting a precise number of questions or minutes for C-208 is asserting something that could not be confirmed against the issuer. Your testing center is the right place to ask what your specific session looks like.

The 70% Threshold at CNM and Why It Is Local

The one concrete published pass threshold located for SACA Silver testing comes from CNM's assessment center, on its page for SACA certifications for the mechatronics program. That page publishes a 70% Silver threshold.

That is a real, citable number, but its scope is limited. It is a center-specific published rule, not a statement that every SACA test site, or every C-208 attempt worldwide, uses 70%. Other centers may publish the same figure, a different figure, or nothing at all. If you test through a different institution, verify the threshold with that center directly.

Silver Versus Gold: Two Different Ways to "Pass"

The word "pass" means different things depending on which SACA level you are attempting. This is the single most common source of confusion about C-208 scoring.

In other words, passing Silver is a knowledge threshold, while earning Gold is a demonstration of skill. If your goal is the stronger credential, plan for both. The C-208 Requirements guide walks through eligibility and how the levels fit together, and the C-208 Certification overview gives the broader picture.

The Seven Objectives Behind Every Score

Since there is no weighting to exploit, the practical way to "protect" your score is to be competent across all seven areas. These are the C-208 domains, matching objectives 208.1 through 208.7:

1. Use status and diagnostic indicators to troubleshoot a PLC
2. Troubleshoot PLC inputs and outputs
3. Troubleshoot PLC power distribution system
4. Troubleshoot a PLC processor
5. Troubleshoot a PLC system with discrete I/O
6. Program and operate a multi-step PLC sequence program
7. Troubleshoot a multi-step PLC sequence program

For a full breakdown of how each area is framed, the C-208 Exam Domains guide goes objective by objective.

Protecting Your Score Domain by Domain

Because every objective is potentially tested and none is published as weighted, the goal is balanced fluency. Here is what a candidate should be able to do in each area.

Domains 1 and 4: Indicators and the processor

Domains 2 and 5: Inputs, outputs, and discrete I/O

Domain 3: Power distribution

Domains 6 and 7: Sequence programming and troubleshooting

The C-208 Cheat Sheet compresses the must-know facts across these areas into a quick review, which is useful in the final days before your test.

Retakes, Notes, and Calculators: Rules That Affect Your Result

Beyond the threshold, several published rules can influence whether you leave with a passing result. All of the following are center-specific, drawn from CNM's published rules, and are not universal C-208 rules.

• Scientific calculator: CNM allows a scientific calculator.
• Prewritten notes: up to five pages of prewritten notes or formulas are allowed, with both sides usable, and they must be surrendered to the proctor.
• Attempt spacing: at least seven days between attempts.
• Attempt limit: up to five attempts per term.

The practical consequence: if you take the five-page notes allowance seriously, build that sheet deliberately around the high-error areas such as indicator interpretation, I/O tracing steps, and sequence logic conditions. But confirm with your center first that notes are allowed at all, since another site may not offer the same allowance.

Fee and Registration Mechanics

Your score is only useful if you can sit the test, so it helps to understand how access works. There are verified local fee examples, but no verified national member or nonmember price.

Treat those as local examples only. They do not establish what another center charges or what SACA charges nationally. Separately, SACA membership benefits can provide certification access for eligible enrolled students and for employees of member companies, and that access is distinct from training tuition and center services. If you are enrolled in a program or employed by a member company, ask whether the test fee is covered before paying out of pocket.

Note also that the retrieved skill standard does not require any particular branded preparation curriculum, so you are not obligated to buy a specific course to qualify. For a fuller treatment of costs, see the C-208 Certification Cost breakdown, and for scheduling logistics see C-208 Exam Dates.

One further clarification: instructional hours, practical assessment time, and college transfer-credit recency are not the same as written-exam duration or certification validity. No universal renewal interval is asserted here, so confirm any validity or recertification questions with SACA or your center.

Sequencing Your Prep Around the Seven Objectives

With an unweighted standard, the smartest scheduling logic is dependency-based: learn the things that make later objectives easier first. Here is one way to order the seven areas across several weeks.

Power and indicators come first because nearly every other troubleshooting scenario depends on them. Sequence work comes last because it assumes you understand the hardware the program controls. If your time is shorter, compress the plan but keep the order. For a fuller roadmap, the C-208 Study Guide expands this into a first-attempt strategy, and you can check your readiness against realistic questions on the C-208 practice test site.
