- No verified, official pass rate exists for C-310 Ethernet Communications 2; any specific percentage you see is unsourced.
- SACA introduced C-310 in a pilot phase on March 17, 2025, and current production availability remains unconfirmed.
- The public standards list seven areas, 310.01 through 310.07, but SACA publishes no weights or exam-form year.
- Local pass requirements, such as one college's 70% rule, are campus policies and not national C-310 statistics.
Why There Is No Published C-310 Pass Rate
If you searched for a C-310 pass rate hoping to find a clean percentage, here is the honest answer: there isn't a verified one. The Smart Automation Certification Alliance (SACA), which governs and administers Ethernet Communications 2, has not published a pass rate, a first-attempt success figure, or a cohort-level outcome report for this micro-credential. Neither have the colleges and training suppliers that align coursework to it.
That matters because pass-rate pages tend to fill the gap with confident-sounding numbers. For a newer credential with a limited public footprint, any specific figure should be treated as invented until a named issuer document backs it. This article takes the opposite approach: it lays out what the available data actually shows, what it cannot show, and how to use that information to judge your own odds.
For a broader look at difficulty without fabricated statistics, see our guide on how hard the C-310 exam is, and for the score side of the question, the companion piece on the C-310 passing score.
What SACA Does Publish About C-310
While outcome statistics are absent, the issuer does publish the competency content behind the credential. SACA's public standards selector, reached by selecting C-310: Ethernet Communications 2, returns Standards 310.01 through 310.07. These are official knowledge and performance competency standards used for certification preparation.
The broader Micro-Credential Descriptions page summarizes the credential in six skill phrases:
- PLC implicit and explicit messaging
- PLC distributed I/O
- VFD-PLC Ethernet communications
- VLAN security
- Wireless Ethernet networks
- IACS network troubleshooting
The detailed standards split explicit and implicit messaging into separate headings, which is why six catalog skills expand into seven standards. What SACA does not publish is just as informative: no percentages per standard, no revision number, no publication date, and no current examination-form year. Without weights, no domain can be identified as the largest, so you cannot responsibly concentrate your study on a single high-value area.
| Data Point | Published for C-310? |
|---|---|
| Seven competency standards (310.01-310.07) | Yes, via SACA's public standards selector |
| Six catalog skill summaries | Yes, on SACA's micro-credential descriptions |
| Per-standard weighting | No |
| Pass rate or first-attempt success rate | No verified figure |
| Question count and written-exam duration | Not publicly verified |
| Universal numerical cut score | Not publicly verified |
| Individual candidate fee for C-310 | No standalone price verified |
Pilot Status and Availability: The Real Data Gap
The biggest reason a pass rate is hard to find is that C-310's production status is itself unsettled. SACA's announcement of March 17, 2025, titled "SACA Releases New Micro-Credentials," explicitly introduced C-310 into a pilot phase. No later announcement confirming that the pilot finished has been verified.
The current indexed issuer catalog carries an asterisk beside C-310. A supplier, Tech-Labs, also marks C-310 with an asterisk and publishes an "In Development" legend. That is corroboration from a supplier, not an issuer production-release notice, and the issuer's own legend for the asterisk was not independently recovered. So the safest reading is that availability needs confirming directly with SACA or your testing site before you plan around it.
A pilot-stage credential generally has a small candidate pool, and small pools rarely produce stable public statistics. Even if SACA tracked internal results, a few early cohorts would not support a trustworthy national percentage. Course listings, directory entries and public objectives do not prove the exam is available at every testing center today.
How to Read Pass-Rate Claims You Find Online
Because the official gap is real, you will encounter secondary claims. Here is how to evaluate the sources that most often surface for this credential.
Supplier and Marketplace Listings
Training suppliers such as Tech-Labs and X-Cal publish skill overviews and, in some cases, flags about development status. These pages describe preparation scope, not candidate outcomes. Notably, X-Cal's description emphasizes ring/star topology and Layer 3 managed switches, which are supplier-specific differences not found in SACA's seven published standards. Treat supplier content as helpful context, not as a substitute for the official standards.
Paid practice listings deserve extra caution. One exact-code practice listing on a document-sharing marketplace has a public preview whose smart-sensor-oriented material does not demonstrate alignment with the current issuer standards. A practice product carrying the right code is not proof that its questions match what C-310 actually assesses.
Course Pages
Lake Land College lists APT-066 Ethernet Communications II at 0.5 credit hour and states that it meets C-310, covering wireless Ethernet, PLC Ethernet communications, industrial VLAN, network security and basic troubleshooting. That is useful curriculum evidence. It is not an outcomes report, and the 0.5 credit value is not an exam timer.
Red Flags
- A precise percentage with no named issuer document, date, or sample size
- "Guaranteed pass" language of any kind
- Pass-rate figures that quietly match a different credential sharing the C-310 label
- Claims of a "2026 exam revision" based only on a publisher's update date, which does not establish an official revision
Key Takeaway
Absence of a pass rate is not a sign the exam is unusually easy or hard. It is a sign the credential is new, still flagged as pilot or in-development, and has not generated public outcome reporting. Prepare against the seven standards, not against a statistic.
Local Pass Rules Are Not National Pass Rates
People often confuse a pass requirement with a pass rate. They are different things. A requirement is the score or standard you must meet; a rate is the share of candidates who meet it. Only the first appears in any public source, and only locally.
For example, Central New Mexico College's current general SACA Silver page publishes a 70% pass requirement, allows notes and scientific calculators, sets a minimum seven-day retake wait, and permits up to five attempts per term. These are that college's general SACA rules. They are not verified national C-310 policies, and the seven-day interval differs from the historical issuer document's 24-hour written-exam retake interval. Current C-310 conditions for open-book use, calculators, adaptive delivery and webcam remote proctoring remain unverified.
| Item | Source Type | Applies Nationally to C-310? |
|---|---|---|
| 70% pass requirement | One college's SACA Silver page | No, local general rule |
| Seven-day retake wait, five attempts per term | Same college page | No, local policy |
| 24-hour written-exam retake interval | Historical SACA process document | Not confirmed for all current centers |
| Universal numerical cut score | None verified | Unknown |
If your institution tells you a threshold, follow it, because your proctor administers your attempt. Just don't generalize it to other candidates. For a deeper treatment of scoring, read our breakdown of the C-310 passing score.
The Seven Standards Behind Any Pass or Fail
Since outcomes data is missing, the most defensible way to estimate your own readiness is to test yourself against each published standard. Here are the seven headings exactly as the issuer frames them, with what each demands in practice. Our full C-310 exam domains guide expands on each.
Domain 1: Program and operate a PLC logic project that uses distributed Ethernet I/O
You work with remote I/O modules on the network rather than only local backplane I/O.
- Adding and addressing distributed I/O devices in the controller project
- Confirming connection status and diagnosing a module that drops offline
- Mapping remote input and output data into program logic
Domain 2: Program and operate a PLC project that uses explicit messaging via Ethernet
Explicit messaging is request-and-response style communication, initiated on demand.
- Configuring message instructions and reading their status and error indicators
- Recognizing when on-demand data exchange suits a task better than cyclic updates
- Troubleshooting a message that never completes
Domain 3: Program and operate a PLC project that uses implicit messaging via Ethernet
Implicit messaging is the scheduled, cyclic exchange used for real-time I/O style data.
- Setting up connections that exchange data at a defined rate
- Understanding how this differs conceptually from explicit messaging
- Verifying that produced and consumed data match on both ends
Domain 4: Program and operate PLC- VFD that uses Ethernet communication
Controlling a variable frequency drive across the network instead of with hardwired signals.
- Configuring network communication between controller and drive
- Commanding start, stop and speed through the network
- Reading drive status and fault information back into the PLC
Domain 5: Configure and test an industrial network VLAN
Segmenting a network logically and proving the segmentation works.
- Assigning ports to VLANs on a managed switch
- Testing that devices communicate within a VLAN and are separated across VLANs
- Linking VLAN use to network security goals
Domain 6: Troubleshoot basic IACS Ethernet network faults
Finding and correcting common faults on an industrial automation and control system network.
- Checking physical layer, link status and addressing first
- Isolating whether a fault sits in a device, a cable, a switch or the configuration
- Documenting the fix and confirming restored communication
Domain 7: Set up and operate a wireless Ethernet network
Bringing wireless links into an industrial Ethernet setup.
- Configuring wireless access and client devices
- Verifying connectivity and stability of the wireless link
- Operating the network and recognizing wireless-specific issues
One quirk worth knowing: the issuer's complete response repeats explicit-messaging knowledge under 310.03 and implicit-messaging knowledge under 310.04, and 310.03 supplies knowledge indicators without a separate performance-indicator list. These source details are reported as published rather than corrected. The practical lesson is to study the conceptual difference between the two messaging types, not just the keystrokes for each.
Silver vs Gold: Two Different Pass Events
Another reason a single "pass rate" would be misleading is that SACA's general framework has two levels, and each is its own pass event, subject to exact C-310 availability.
- Silver requires passing an online proctored written knowledge examination.
- Gold adds a successfully observed hands-on performance using SACA-approved equipment, taken after Silver.
A blended statistic would hide the fact that a knowledge exam and a hands-on observation test different skills. A candidate fluent in VLAN theory can still stumble when configuring a real switch under observation, and vice versa. Assessment is administered through SACA's portal, authorized member testing centers and qualified institutional Silver and Gold proctors; no separate Pearson VUE, PSI or Prometric provider is identified. Indexed issuer text supports immediate written results, but exact C-310 question count, item types, written duration and practical duration are not publicly verified. See our C-310 requirements guide for eligibility and sequencing details.
Building a Domain-Ordered Prep Plan
With no weights published, equal attention across all seven standards is the defensible default. Sequence matters, though, because some skills build on others. A reasonable ordering follows how the technologies layer in a real cell:
Distributed I/O and Troubleshooting Basics
- Work Domain 1 first, since every later domain assumes a working network connection
- Start Domain 6 habits early: check link, address, then configuration
Explicit vs Implicit Messaging
- Study Domains 2 and 3 back to back so the contrast stays sharp
- Build one exercise for each and explain in your own words why they differ
VFD Communications and VLANs
- Domain 4: command and monitor a drive over the network
- Domain 5: configure a VLAN and prove isolation with tests
Wireless and Full Review
- Domain 7: set up and verify a wireless link
- Revisit weakest domains and rehearse fault-finding across all seven
For a fuller walkthrough, our C-310 study guide expands this approach, and the C-310 cheat sheet condenses the must-know facts for last-minute review. Issuer preparation guidance permits suitable preparation methods without requiring a particular course, curriculum or training-equipment brand, though Gold equipment must meet SACA standards.
What You Can Measure Yourself
You cannot measure the population's pass rate, but you can measure your own readiness precisely. Treat each standard as a pass/fail checkpoint and keep a running log.
- Per-standard confidence: For each of the seven standards, can you explain the concept and perform the task without notes?
- Error patterns: Note whether misses are conceptual (mixing up explicit and implicit) or procedural (misconfiguring a VLAN port).
- Fault-finding speed: Practice isolating a fault in a deliberately broken setup, since Domain 6 rewards method over guessing.
- Retake planning: Know your site's retake rules before you sit, since local intervals and attempt limits vary.
If you want timed, scenario-style practice organized around the seven areas, the C-310 practice test site is built for exactly that kind of self-assessment, and you can explore more at the main practice hub. Pair that with the cost and value context in our C-310 certification cost breakdown and the C-310 ROI analysis, which both avoid inventing salary or fee figures that sources do not support.
Key Takeaway
Since no public pass rate exists, your best predictor is coverage: can you demonstrate every one of the seven standards, including the explicit-versus-implicit distinction, without prompts? Close the gaps domain by domain.
Frequently Asked Questions
No official or verified pass rate has been published for C-310 Ethernet Communications 2. SACA has not released first-attempt or overall success statistics, and the credential's pilot-phase status makes stable public figures unlikely. Be skeptical of any specific percentage that lacks a named, dated issuer source.
No. A 70% requirement appears on one college's general SACA Silver page, along with its own retake rules. That is a local policy, and a universal numerical cut score for C-310 has not been publicly verified. Follow the rules your testing site gives you.
SACA introduced C-310 into a pilot phase on March 17, 2025, and no later announcement confirming completion of that pilot has been verified. The issuer catalog and a supplier both mark C-310 with an asterisk. Confirm current availability with SACA or your authorized testing site before scheduling.
Unknown. SACA publishes Standards 310.01 through 310.07 but no percentages, so no domain can be identified as largest. Prepare across all seven, paying particular attention to the conceptual difference between explicit and implicit messaging.
Not directly, since no rate is published. A better question is whether the skills, such as distributed I/O, VLAN configuration and network troubleshooting, fit your role. For eligible students of member institutions and employees of member companies, SACA's general membership benefits provide certification without additional certification fees, though C-310's exact availability still needs confirming. Our salary guide explains why no credential-specific earnings premium can be claimed.
