- SACA does not publicly disclose a pass rate for Hydraulic Systems 2 (C-354); any specific percentage you see is unverified.
- Official sources describe C-354 through six preparation topics, not weighted exam domains or a released blueprint.
- Catalogue entries carry an "In Development" footnote, so a launched exam and booking path are unconfirmed.
- Judge your readiness by hands-on circuit competence across all six topics, not by chasing a statistic.
The Short Answer: No Public Pass Rate Exists
If you searched for the C-354 pass rate hoping for a clean percentage, here is the honest finding: the Smart Automation Certification Alliance (SACA) does not publish one for Hydraulic Systems 2 (C-354). No pass percentage, first-time pass figure, or cohort success statistic appears in the issuer's catalogue, in the secondary directory listings that repeat its scope, or in any provider page we reviewed.
That matters because this credential is a hydraulics micro-credential, not a high-volume professional licensure exam with annual statistical reports. Treat the absence of data as a real result of the research. Any number presented as "the" C-354 pass rate should be treated with suspicion, and the rest of this article explains why, what you can rely on instead, and how to prepare so the question stops mattering.
Why the Number Is Missing
Several overlapping reasons explain why no pass rate is available for C-354, and understanding them helps you read the rest of the web more critically.
The credential's status is not fully settled
SACA's catalogue lists the exact C-354 entry with a starred "In Development" footnote, and an independent provider's listing retains that same status. A credential still being developed, or only recently released, has no meaningful track record. A pass rate is a ratio of successful candidates to total candidates over a defined period. Without a confirmed launch date, a released assessment, or a current booking path, there is no defined candidate population to measure.
SACA does not publish outcome statistics
SACA's general materials describe how certification works: a portal, authorized member organizations and testing-center proctors, and tiered pathways. They do not describe a practice of reporting aggregate pass percentages by credential. The issuer's documentation focuses on process and scope, not outcomes.
Results are administered through partners
Because testing runs through authorized member organizations and proctors rather than a single centralized vendor, there is no single data pipeline that would produce a public statistic. Even if individual training centers track their own learners' results, those figures reflect their own cohorts, their own prerequisites, and their own teaching, and they cannot be generalized into a national C-354 pass rate.
What the Public Record Does Confirm
While the pass rate is unavailable, a surprising amount about the credential's scope is documented. Here is what can be stated with confidence, and what cannot.
| Item | Status |
|---|---|
| Issuer | Smart Automation Certification Alliance (SACA) |
| Credential name | Hydraulic Systems 2 (C-354) |
| Scope | Six preparation topics on connecting, adjusting, operating and analyzing heavy-duty industrial hydraulic circuits |
| Pass rate | Not publicly disclosed |
| Numerical passing criteria | Unverified |
| Question count and format | Unverified |
| Exam fee | Unverified |
| Launch status | Catalogue footnote reads "In Development" |
| Renewal | Secondary directories suggest no CEU or re-examination requirement; not an issuer guarantee |
Notice how many rows read "unverified." That is not a gap in this article; it reflects the public record. For a deeper look at what is and is not established about format and prerequisites, see our guide to C-354 requirements and eligibility and the breakdown of what the C-354 passing score does and does not tell you.
How to Spot a Fabricated Pass Rate
Because searchers want a number, low-quality pages tend to supply one. When researching any hydraulics credential, apply these checks to a claimed C-354 pass rate:
- Ask for the denominator. A legitimate pass rate states how many candidates tested and over what period. If a page cannot say, the figure is decorative.
- Check the issuer. A percentage attributed to "C-354" without naming SACA may belong to a different credential that shares the code. Several unrelated programs use the same label.
- Look for a primary source. If the number is not traceable to SACA, an authorized proctor, or a named training provider with a stated method, it is unverifiable.
- Distrust round, confident figures. Precise-sounding percentages for a credential whose launch status is still listed as in development are a red flag.
- Separate course completion from exam success. A training provider's "graduation rate" or "success rate" measures its own course, not the SACA assessment.
This pairs naturally with understanding how difficult the C-354 exam is likely to be, since difficulty is better assessed from content than from a rumored percentage.
Reading the Six Domains as a Difficulty Signal
Without a pass rate, the most useful evidence about difficulty is the content itself. SACA's preparation description lists six topics. They are unweighted preparation components, not an official blueprint with percentage allocations, so no domain should be assumed to carry more exam weight than another. They do, however, reveal the kind of competence the credential is aiming at: working with heavy-duty industrial circuits, not memorizing definitions.
Domain 1: 2-stage directional control valves
Candidates should understand how a pilot stage shifts a main spool and why that two-stage arrangement suits higher flows.
- Pilot supply and drain behavior and what happens when either is lost
- Why a valve may fail to shift at low system pressure
- Reading the symbol and tracing flow paths through each shifted position
Domain 2: subplate-mounted pressure and flow control valves
Subplate mounting makes valves serviceable without breaking line connections, and it shapes how circuits are assembled and troubleshot.
- Distinguishing relief, reducing and sequence functions in a circuit
- Flow control placement: meter-in versus meter-out effects on actuator behavior
- Adjustment order and how one setting influences another
Domain 3: pressure-compensated variable volume pumps
These pumps adjust output to system demand, which changes heat, efficiency and relief-valve behavior compared with fixed-displacement designs.
- How the compensator sets maximum pressure and reduces flow at the setting
- Reasons for low output: wear, setting, or supply restriction
- The interaction between compensator and any system relief
Domain 4: cylinders cushions
The source wording is preserved here. Cushions decelerate a cylinder near the end of stroke to limit shock.
- How cushion adjustment and check-valve return paths affect speed and re-start
- Symptoms of over-tight or too-loose cushioning
- Why cushioning affects both component life and circuit behavior
Domain 5: counterbalance valves
Counterbalance valves control overrunning loads and hold suspended loads in place.
- Pilot ratio and its role in opening against a load
- Preventing runaway and managing load-holding stability
- Troubleshooting chatter or unstable lowering
Domain 6: unloader valves
Unloader valves divert pump flow to tank at low pressure when full flow is not needed, saving energy and reducing heat.
- Typical use with accumulator or dual-pump arrangements
- How the cut-in and cut-out behavior is set
- Telling an unloader apart from a relief valve by function
The common thread is analysis: candidates are expected to connect, adjust, operate and analyze circuits. That implies the assessment, in whatever form it takes, rewards understanding of cause and effect inside a circuit. A candidate who can only recite component definitions is the person most likely to struggle, and that is a better predictor of difficulty than any rumored percentage. For a topic-by-topic walkthrough, see the complete guide to all six C-354 content areas.
Better Proxies Than a Pass Percentage
If the headline number is unavailable, use indicators you can actually measure about yourself.
Can you trace a circuit cold?
Pick a schematic that combines a 2-stage valve, a pressure-compensated pump, and a counterbalance valve. If you can narrate the flow, identify each pressure setting, and predict what happens when one component fails, you are working at the level the scope describes.
Can you explain function, not just name?
An unloader and a relief valve both move oil to tank. A candidate ready for this credential can explain precisely when each acts and why a circuit needs one, the other, or both.
Do you have hands-on exposure?
The wording about "connecting, adjusting, operating" points toward practical work. SACA's general Gold-tier policy involves observed performance on approved equipment, though whether that applies to C-354 is unconfirmed. Either way, time on real or simulated circuits builds the intuition that written practice alone cannot.
Key Takeaway
Replace "What percentage pass?" with "Can I diagnose a misbehaving circuit in each of the six topic areas?" The second question is answerable today and predicts your result far better than any rumored statistic.
Confirm the logistics before you invest
Because fees, format, durations and booking paths are unverified, contact SACA or an authorized member organization before committing money. Our breakdown of C-354 certification cost explains which pricing details remain open, and the guide to C-354 exam dates and scheduling covers what can and cannot be confirmed about availability.
A Domain-Ordered Readiness Plan
Generic study advice is plentiful. What is specific to C-354 is the order in which the topics build on one another. Pumps and directional valves underpin everything else, so they come first; the load-handling and energy-saving valves make more sense once the basics are secure.
Pumps and directional control
- Pressure-compensated variable volume pumps: compensator behavior and low-output causes
- 2-stage directional control valves: pilot and main-stage flow tracing
Pressure and flow control
- Subplate-mounted pressure and flow control valves: adjustment order and meter-in versus meter-out
- Work two or three combined schematics end to end
Actuator protection and load control
- Cylinders cushions: adjustment effects and failure symptoms
- Counterbalance valves: pilot ratio and stability
Energy management and integration
- Unloader valves: cut-in and cut-out logic and where they differ from relief valves
- Mixed-topic troubleshooting scenarios across all six areas
Use the week-four mixed scenarios as your honest readiness test. For a fuller sequencing approach, the C-354 study guide expands on pacing, and the one-page C-354 cheat sheet is a handy final review. When you want timed, scenario-style practice across these topics, the C-354 practice test offers a way to check yourself, and you can explore more practice questions as your confidence grows.
Weigh the credential's value separately
Pass-rate curiosity often masks a deeper question: is this worth pursuing at all? That depends on your role and employer, not on a statistic. Hydraulic technicians, maintenance staff and fluid-power learners are the people this scope speaks to. For that analysis, see whether the C-354 certification is worth it.
Frequently Asked Questions
It is not publicly disclosed. SACA does not publish a pass rate for Hydraulic Systems 2 (C-354), and no verified source provides one. Treat any specific percentage as unverified unless it can be traced to SACA or an authorized testing provider with a stated method and candidate count.
The credential's catalogue entry carries an "In Development" footnote, results flow through authorized member organizations rather than one central vendor, and SACA's materials do not describe publishing outcome statistics. Together, these leave no defined dataset from which a first-attempt figure could be calculated.
Difficulty is better judged from content. The six topics emphasize connecting, adjusting, operating and analyzing heavy-duty hydraulic circuits, which rewards genuine circuit understanding over memorization. Candidates comfortable tracing flow and diagnosing faults across all six areas are best positioned.
No weights were verified. The six topics are unweighted preparation components from SACA's description, not a formal exam blueprint. You should not assume any one topic, such as pumps or counterbalance valves, is weighted more heavily than the others.
Master all six topics, practice tracing combined circuits, and confirm logistics such as fees, format and booking directly with SACA or an authorized provider. Our C-354 certification overview and C-354 training pages are good starting points for next steps.
