What the Data Actually Shows About C-307 Pass Rates
If you searched for the C-307 pass rate, here is the straight answer: the Smart Automation Certification Alliance (SACA) does not publish a headline pass-rate percentage for the Electronic Systems Installation 1 (C-307) micro-credential in any of the issuer materials we reviewed. That means there is no official figure to quote, and this article will not invent one.
What we can do is lay out what the available evidence does tell you: how the assessment is structured, who is eligible to take it, which skill areas it centers on, and where candidates tend to be most exposed. That context is more useful for planning than a single number would be, because pass outcomes for a skills-based electronics installation credential depend heavily on your hands-on background.

Why SACA Does Not Publish a Single Pass-Rate Figure
There are structural reasons a clean pass-rate number is hard to come by for this credential, and understanding them helps you interpret everything else you read.
It is a micro-credential delivered through member institutions
SACA's certifications are available to employees or students of SACA members. Many candidates take the assessment through a school or employer program, often as part of a structured course sequence. Outcomes in that setting reflect instructor quality, lab access, and cohort preparation as much as the exam itself. A pooled national percentage would blend very different populations.
Two recognition levels, not one exam
SACA offers Silver and Gold recognition. Silver is tied to the proctored written knowledge assessment. Gold adds a hands-on performance assessment. A single "pass rate" would conflate a written test with a practical one, which is why even a hypothetical statistic would need to be split by level to mean anything.
Our research limits
The sources behind this article include SACA's micro-credential descriptions, its March 17, 2025 announcement of new micro-credentials, and the first page of its Gold and Silver certification process document. Direct retrieval of additional SACA pages and PDF pages failed, so we make no claims about any unseen blueprint or process detail. If SACA publishes outcome data elsewhere, we have not seen it.
Silver vs. Gold: Two Different Hurdles
The single most useful framing for your odds is recognizing that the two SACA levels test different things. Here is how they compare based on the issuer's process description.
| Feature | Silver | Gold |
|---|---|---|
| Core assessment | Proctored written knowledge assessment | Written assessment plus a hands-on performance assessment |
| Delivery | SACA online testing portal or Authorized Testing Centers | Written portion as with Silver; performance portion uses SACA-approved equipment |
| What it rewards | Knowing the standards, sequences, and terminology | Knowing them and executing installation tasks correctly |
| Main risk for candidates | Gaps in recall across the eight skill areas | Weak bench skills: terminations, soldering, routing, grounding |

Who Sits the C-307 Assessment
Eligibility shapes outcomes. Per SACA's process materials, candidates must be employees or students of a SACA member, and no specific preparatory course is required. That open door produces a mixed candidate pool:
- Students in industrial or mechatronics programs who have lab time with panels, PLCs, and drives.
- Working technicians and apprentices whose employer is a SACA member and who already do installation work.
- Career-changers who understand electronics theory but have not yet mounted or wired a cabinet.
Candidates in the first two groups typically have an easier path on the performance-oriented material; career-changers often need to deliberately build practical familiarity. Full eligibility details are in C-307 Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Education members can provide certifications to enrolled students without an individual certification charge. That is an education-member benefit, not a universal retail exam price, so do not assume it applies unless your school is a SACA education member. See C-307 Certification Cost 2026: Complete Pricing Breakdown for how costs are structured.
Where Candidates Lose Points: The Eight Domains
SACA's published key skills for Electronic Systems Installation 1 (C-307) break down into eight preparation topics. SACA does not weight them in the sources we reviewed, and they do not establish an official exam-domain count, so treat them as the issuer's skill list rather than a scoring blueprint. Based on how these skills are typically learned, here is where the risk sits.
Domains 1 and 2: Installation Safety Rules and Proper PPE
These look easy and are often under-prepared because they feel like common sense. Expect scenario-style thinking about safe working practice and selecting protective equipment for a task.
- Know the safe sequence for working on or near energized equipment
- Match PPE to the hazard, not just the job title
- Understand why safety rules exist so you can reason through unfamiliar scenarios
Domain 3: Reading Wiring Installation Diagrams with PLCs/HMIs/VFDs
Diagram literacy is a gatekeeper skill. If you cannot trace a signal from field device to controller I/O, later domains get harder.
- Interpret symbols, terminal designations, and wire identification
- Follow power and control paths for PLCs, HMIs, and VFDs
- Translate a drawing into physical routing and termination decisions
Domains 4 and 5: Cabinet Mounting and Wire Routing/Grounding
This is the heart of installation craft. Questions and performance tasks here test layout judgment and electrical hygiene.
- Panel layout, spacing, and mounting practices for PLCs, HMIs, and VFDs
- Separating power wiring from low-level signal wiring
- Grounding and bonding practices for controllers and drives
Domain 6: Soldering/De-soldering to Component Terminals and Printed Circuit Boards
The most hands-on skill on the list and the one candidates without bench time tend to find hardest to fake. Written questions probe technique and quality criteria; a Gold performance task would put it into practice.
- Recognize a good joint versus a cold or overheated one
- Understand heat control, tinning, and safe de-soldering technique
- Know the difference between working on terminals and working on PCBs
Domains 7 and 8: Modbus/Ethernet Networks and Analog Input Transmitters and Sensors
These connect the installation to the wider control system. Expect questions about physical layer setup and signal behavior.
- Cabling, addressing, and basic configuration concepts for Modbus and Ethernet
- How analog transmitters and sensors are wired and what their signals represent
- Common installation faults that show up as bad readings or dead communication

Question Style and What It Means for Outcomes
SACA describes its written assessments as proctored knowledge tests delivered through its online testing portal or at Authorized Testing Centers. We do not have access to an official blueprint, question count, or time limit, and we will not make one up. One caution: SACA's published micro-credential learning-hour guidance describes expected learning time, not a written-exam timer, so do not confuse the two when planning your test day.
What the skill list does tell us is the kind of thinking the credential rewards: applied, procedural knowledge. Expect questions that ask what you would do, in what order, and why, rather than purely abstract theory. That has two practical consequences for pass odds:
- Memorization alone is a weak strategy. A candidate who can recite definitions but has never terminated a wire will struggle more than the numbers suggest.
- Cross-domain questions are likely. Routing, grounding, and diagram reading overlap; a single scenario can touch several skills at once.
How to Read Pass-Rate Claims You Find Online
Because the acronym "C-307" is shared by several unrelated credentials and course codes, pass-rate and salary content online is frequently mixed up. Use this checklist before trusting any figure:
- Check the issuer. Does the page name SACA and the Electronic Systems Installation 1 micro-credential, or is it about a different certifying body?
- Look for a source. A real statistic cites where it came from. "Industry average" or "studies show" without a link is a red flag.
- Watch for mismatched details. Fees, domain names, or exam lengths that do not match SACA's materials usually belong to another credential.
- Separate Silver from Gold. A claim that ignores the written versus performance split is not describing this credential accurately.

Tilting the Odds: A Domain-Ordered Prep Plan
With no published pass rate to anchor expectations, the best move is to prepare in a sequence that mirrors how the skills build on each other. This is the one planning section in the article; it is tied to the eight domains rather than generic scheduling advice.
Safety, PPE, and Diagram Reading (Domains 1-3)
- Lock in safety rules and PPE selection first; they frame every later task
- Practice tracing signals through wiring diagrams that include PLCs, HMIs, and VFDs
Cabinet Work (Domains 4-5)
- Study mounting layout, then routing and grounding in the same sitting since they interact
- Sketch a panel layout from a diagram and check it against signal-separation rules
Bench and Network Skills (Domains 6-8)
- Get real soldering and de-soldering time if you can; this is the hardest domain to learn from text alone
- Review Modbus and Ethernet installation basics, then analog transmitter and sensor wiring
Mixed Scenario Review
- Take timed scenario practice that blends domains
- Revisit your weakest domain and any area where you guessed

Key Takeaway
Allocate your extra time to the domain where your hands-on experience is thinnest. For most written-focused candidates that is soldering/de-soldering; for bench-focused technicians it is often diagram reading and Modbus/Ethernet setup.
Registration and Fee Mechanics That Affect Your Attempt
Practical logistics can influence outcomes more than people expect, because a rushed or mismatched attempt hurts performance. Based on SACA's published process:
- Membership first. You must be an employee or student of a SACA member. Confirm your organization's status before planning a test date.
- Delivery options. The proctored written assessment is administered through SACA's online testing portal and Authorized Testing Centers.
- Gold requires equipment. The hands-on performance assessment uses SACA-approved equipment, so confirm access to it if you are aiming for Gold.
- Fees depend on your route. Education members can provide certifications to enrolled students without an individual certification charge; other routes may differ, and we have no verified universal retail price to report.
