C-259 Pass Rate 2026: What the Data Shows

What a C-259 Pass Rate Can and Cannot Tell You

Candidates searching for a C-259 pass rate usually want one number: the percentage of people who pass on the first try. Here is the honest answer for Rigging Systems 1: there is no verified, publicly published pass rate we can cite. The issuer does not release a first-attempt percentage in the sources we reviewed, and the college and government pages that describe the credential do not either. Any article that quotes a precise figure for this credential is guessing or borrowing a number from somewhere else.

That does not leave you empty-handed. What the data does show is the structure of the credential: what it covers, how the broader SACA program assesses candidates, and which topic areas are inherently harder to master. Those facts let you estimate your own readiness far better than a headline percentage would. For a broader look at difficulty, see our guide on how hard the C-259 exam is.

Which Credential We Mean by C-259

The label "C-259" is shared by several unrelated credentials in different fields. This article is exclusively about Rigging Systems 1, a micro-credential from the Smart Automation Certification Alliance (SACA). It is an individual rigging micro-credential listed as an elective in SACA's Automation Systems Specialist pathway. It is not the entire specialist certification, and it is not a crane-operator or certified-rigger examination from another body.

The scope is practical and equipment-focused: selecting, sizing, assembling, adjusting and using rigging apparatus to lift, move or transport a load. If you want the definitional background first, our explainers on what C-259 is and what C-259 stands for cover the naming in more detail.

How SACA Assessment Works

Because no C-259-specific pass statistics are published, the most useful context is the assessment model SACA programs use. Hawkeye Community College describes a two-stage structure for the SACA Automation Systems Specialist pathway: an online written knowledge examination at the Silver level, followed by an additional hands-on performance assessment for Gold.

One caution: this is a program-level description. It does not establish a current C-259 appointment procedure, a question count, or a written-test timer. Treat any claimed exact question total or time limit for C-259 with skepticism until SACA or an assessment center confirms it. For score expectations, see our page on the C-259 passing score, and for registration mechanics, the C-259 certification cost breakdown.

Availability: Confirm Before You Plan

Here is a wrinkle that most pass-rate articles skip. The college and government sources we reviewed list C-259 Rigging Systems 1 as part of the SACA offering, and the Indiana profile describes the certifications as nonexpiring. That is a statement from a government source, not a freshly verified issuer maintenance policy. Meanwhile, at least one vendor catalog labels the micro-credential as "In Development."

This also explains why a pass rate is hard to pin down: if the assessment is newly rolled out or still in development in some channels, there may simply be too few completed attempts to publish meaningful statistics.

Where Candidates Lose Points: The 17 Topics

The preparation description for C-259 lists 17 topic lines. These are unweighted preparation topics, not a formal examination blueprint, so we cannot tell you how many questions each one gets. They do, however, tell you exactly what you are expected to know. They break naturally into three groups:

• Hardware and lifting devices: hooks and eyebolts, shackles, manual hoists, powered hoists, spreader beams.
• Slings and hitches: slings and hitches generally, basket slings, choker slings, bridle slings, wire rope slings, chain slings.
• Skills and calculations: adhering to rigging safety rules, identifying rigging components given a part number, calculating load weight and balance, determining center of gravity, calculating rated load of hitches, calculating crush force.

Our complete guide to all 17 C-259 content areas goes deeper on each line. Below, we focus on the areas where preparation effort pays off most.

The Math Cluster: Domains 14 to 17

Four topic lines are calculation-driven, and they are where a prepared candidate separates from an unprepared one. You cannot bluff a rated-load calculation. Either you know how the hitch configuration changes capacity or you do not.

Hardware and Sling Topics That Trip People Up

The hardware and sling topics are more about recognition and judgment than arithmetic, but they still reward careful study.

Sling Types Are Easy to Confuse

Basket, choker, and bridle slings are three distinct ways of connecting a sling to a load, each with different capacity and control characteristics, and Domains 6, 7, and 8 each name one. Add wire rope slings (Domain 10) and chain slings (Domain 11), which are defined by construction material rather than hitch style, and it is easy to blur categories. A useful discipline is to keep two questions separate: what is the sling made of, and how is it rigged around the load?

Hoists and Hardware

Manual hoists (Domain 3) and powered hoists (Domain 4) appear as separate topics, so expect to compare how they are operated, controlled, and inspected. Hooks and eyebolts (Domain 1) and shackles (Domain 2) are the connecting hardware, and spreader beams (Domain 9) change how force is carried through the rigging. Understand not just what each item is, but why you would choose it for a given lift.

Safety Rules and Part Numbers

Domain 12, adhering to rigging safety rules, is the thread connecting everything else. Domain 13, identifying rigging components given a part number, is a more specialized skill: you may be asked to interpret a part number to determine what a component is. Practice reading catalog-style identifiers rather than assuming you will recognize parts by sight alone. For a quick-reference companion, see our C-259 cheat sheet.

A C-259 Preparation Sequence by Domain

Rather than a generic schedule, here is a sequence built around how the C-259 topics depend on each other. Adjust the pacing to your own timeline. For a fuller plan, our C-259 study guide expands on this approach.

The reasoning behind the order: hardware and sling vocabulary comes first because the calculation topics assume you already know what the components are. Placing the calculation chain in the third week lets you apply it to configurations you have already studied. For difficulty calibration, you can use our practice questions to find your weakest domains before the final review.

Who Values the Credential

C-259 sits inside an automation and advanced manufacturing context, so its natural audience is learners in those programs and the employers who hire them. Hawkeye Community College lists it within its Automation Systems Specialist pathway, and Indiana's workforce development agency includes a C-259 Rigging Systems 1 profile among its industry certifications. Roles that involve lifting and moving equipment or materials, such as industrial maintenance, millwright-adjacent work, and plant installation, are where the skills apply.

We do not cite specific wage figures here. The Indiana profile includes wage data dated October 2023, but we cannot responsibly attach a salary to this credential on its own. If earnings are your main question, read our C-259 salary guide and the ROI analysis, and browse C-259 jobs for the kinds of roles that reference it.
