C-310 Passing Score 2026: Exactly What You Need to Pass

The Short Answer: No Public Cut Score Exists

If you searched for the C-310 passing score hoping for a clean number like "70%" or "750 out of 1000," here is the honest answer: no universal numerical cut score for C-310 (Ethernet Communications 2) has been publicly verified. The Smart Automation Certification Alliance (SACA), which governs and administers this credential, does not publish a percentage threshold, a scaled-score range, or a scored-item count for the C-310 written assessment in any public source reviewed for this article.

That matters because many pages that rank for this query quietly import a number from somewhere else. "C-310" is a code shared by several unrelated credentials, and a passing score from one of them has no bearing on Ethernet Communications 2. This guide covers only the SACA micro-credential built around PLC Ethernet messaging, distributed I/O, VFD communications, VLANs, wireless Ethernet, and industrial network troubleshooting. If you want a broader orientation first, start with What Is C-310? or What Is C-310 Certification?.

What we can do is lay out what is verified, what is local policy, what is unknown, and how to prepare so that the unknown number stops being your problem. If you want to start pressure-testing yourself right away, the C-310 practice test site is built around the seven published standards.

What Is and Isn't Verified About C-310 Scoring

Separating confirmed facts from assumptions is the most useful thing a candidate can do here. The table below summarizes the scoring-related details at the time of writing.

Notice what is absent: any figure you could confidently write on a flashcard as "the number to beat." The 2019 general pilot timer that appears in older SACA material is not assigned to this later credential, so you should not treat it as a C-310 time limit either.

How Silver and Gold Change What "Passing" Means

Under SACA's general assessment framework, "passing" is not one event. It depends on which level you are pursuing, subject to exact C-310 availability.

Silver: the written knowledge exam

Silver requires success on an online proctored written knowledge examination. Assessment is administered through SACA's portal, authorized member testing centers, and qualified institutional proctors; no separate Pearson VUE, PSI, or Prometric provider is identified. Indexed issuer text and reviewed process evidence indicate immediate written results, so you typically learn the outcome right away rather than waiting for a mailed score report.

Gold: written credential plus observed performance

Gold builds on Silver. It requires the relevant written credential and then successfully observed hands-on performance using SACA-approved equipment. For C-310 this means demonstrating, not just describing, tasks such as getting a PLC to exchange data with distributed Ethernet I/O or configuring an industrial VLAN. The practical element is evaluated by observation, so "passing" Gold is a competence judgment rather than a percentage you can pre-compute.

For a deeper look at how the two levels differ in preparation, see the C-310 Study Guide and the C-310 requirements overview.

Local Pass Rules You Might Encounter

Because SACA assessments run through member institutions, you may meet a pass requirement written into your school's or testing site's own policy. The clearest public example comes from Central New Mexico Community College (CNM), whose general SACA Silver page publishes:

• A 70% pass requirement
• Notes and scientific-calculator allowances
• A minimum seven-day retake wait
• Up to five attempts per term

The practical takeaway is to ask your own testing site three questions before exam day: what pass threshold applies, whether notes or calculators are allowed, and how long you must wait to retake. Current C-310 open-book rules, calculator conditions, adaptive delivery, and webcam remote-proctoring requirements remain unverified, so your proctor's answer outranks anything you read online, including here.

Seven Standards You Must Clear, Not Average Away

SACA's public standards selector lists seven C-310 standards (310.01 through 310.07). Because no percentages are published, you cannot responsibly assume any standard is "low weight" and safe to skim. The seven headings are:

Two source quirks are worth knowing so they do not confuse you. Standard 310.03 supplies knowledge indicators without a separate performance-indicator list, and the full response repeats explicit-messaging knowledge under 310.03 and implicit-messaging knowledge under 310.04. These details are preserved here as published rather than silently corrected. A full walkthrough of each content area lives in the C-310 exam domains guide.

Why the six-skill catalog summary still matters

SACA's broader micro-credential description lists six skill phrases: PLC implicit and explicit messaging, PLC distributed I/O, VFD-PLC Ethernet communications, VLAN security, wireless Ethernet networks, and IACS network troubleshooting. The seven detailed standards simply split messaging into two headings. Neither list is weighted, and neither is described as exhaustive exam coverage. Some suppliers describe the credential differently; for instance, X-Cal emphasizes ring/star topology and Layer 3 managed switches. Those supplier-specific details were confirmed on their own page but are not part of SACA's seven standards, so do not let them displace your core preparation.

Check Availability Before You Chase a Number

There is a prior question that matters more than the cut score: can you actually sit this exam right now? A verification hold remains on current production-exam availability and the final current examination version.

The known timeline is short. SACA's March 17, 2025 announcement introduced C-310 into a pilot phase. No later exact C-310 announcement confirming the end of that pilot was verified. The current SACA catalog carries an asterisk beside C-310, and Tech-Labs, a supplier, also marks it with an asterisk plus an "In Development" legend. That is supplier corroboration, not an issuer production-release notice, and the issuer's own legend could not be independently recovered. Course listings and directory entries do not prove that every testing center offers the exam today.

Also be wary of marketing that implies a "2026 exam revision." Publisher dates and paid question-bank update claims do not establish an official 2026 revision. Years in articles like this one date the editorial guidance, not the exam form.

Building a Readiness Standard Without a Published Cut Score

When the target number is unknown, set your own bar high and tie it to the standards. Because SACA states that preparation methods are flexible and does not require a specific course or training-equipment brand, you can organize practice around the seven standards directly. One compact way to sequence the work:

This sequence puts foundational skills first and leaves troubleshooting for later, when you have enough working knowledge to diagnose what breaks. For a fuller version of this approach, see the C-310 Study Guide, and for a sense of effort, the difficulty guide.

A self-set readiness bar

Since you cannot measure yourself against an official percentage, use a conservative personal rule: you are ready for Silver when you can answer mixed questions on all seven standards consistently, with no standard noticeably weaker than the rest, and you are ready for Gold when you can perform each task unaided on approved-style equipment. Regular timed sets from the C-310 practice tests help you see whether your accuracy holds across every standard rather than only your favorites.

What a pass does and doesn't change

Passing is a competency milestone, not a verified salary event. No C-310-holder salary series or earnings premium has been verified, and wages from C-212, generic Ethernet/IP jobs, or broad automation roles should not be transferred to this credential. If return on investment is your concern, read the C-310 ROI analysis and the cost breakdown, which explain how membership-based certification benefits work without inventing a price.

Frequently Asked Questions

The most dependable preparation strategy is also the simplest: confirm availability and local rules with SACA or your member institution, then prepare to the seven published standards rather than to an unverified number.
