The CCO Foundation Drill Rig Operator (FDR) designation certifies operators of foundation drill rigs under CCO’s Drill Rig Operator program. Certification requires the Drill Rig Core written examination of 90 questions in 90 minutes and the FDR specialty written examination of 45 questions in 45 minutes, with a calculator permitted, plus a practical examination, with certification valid five years. This program covers the written examinations only.

What this designation certifies
A foundation drill rig makes holes that become buildings: rotary machines that turn augers and drilling tooling into the ground to open shafts, which are then cased or supported, filled with a rebar cage, and concreted into drilled shaft foundations. The operator manages torque and crowd, reads the ground through the tooling, controls spoil, keeps the shaft true and stable, flies the cage in with the rig or a service crane, and secures the open hole – a process discipline closer to manufacturing than to lifting, performed outdoors in dirt. CCO’s Drill Rig Operator program, built with the ADSC, certifies that operator through a Core written examination, an FDR specialty written examination, and a practical. This program covers the written examinations only.
What separates drill rig operation from every crane designation in this batch is that the machine’s product is underground and invisible. The operator cannot see the shaft; it is known through torque, crowd pressure, spoil character, and depth measurement, and its quality – plumb, clean, stable, to depth – is inferred from instruments and spoil until the cage and concrete prove it. The outline reflects that epistemology: technical knowledge at 31% carries the machine and ground science; tooling, a domain no crane outline has, covers the augers, buckets, core barrels, and casing the ground dictates; and capacity and stability charts replace load charts, because the rig’s lifting is in service of the hole, not the point of it.

What the written examination covers
The five domains are shared by Core and specialty, so the two sittings examine one discipline at two depths. Pre-operations and site conditions, at 23%, covers the job hazard analysis habit the handbook formalises – the JHA is named content – together with ground reading, rig positioning, and the area of influence around an open shaft. Operations at 34% is the drilling cycle: setup, drilling, spoil management, tooling changes, cage handling, and securing shafts. Technical knowledge at 31% covers the machine – kelly bar, crowd, mast, rotary – and the ground and stability science beneath it. Communications at 8% suits a crew process worked over engine noise. Tooling, small at 4%, is disproportionately distinctive: it is the vocabulary of the trade.
Pre-Operations / Site Conditions — ~23%
The opening domain formalises how a drilling job begins: the job hazard analysis as a working method, site and ground condition assessment, rig positioning and setup for stability, utilities and obstructions above and below ground, spoil and slurry management areas, and the area of influence around the work and the open shaft. It examines preparation as a technical act – the ground read before it is drilled.
Operations — ~34%
The outline’s centre: the drilling cycle worked end to end. Rig setup and levelling, drilling with auger and tooling under torque and crowd control, spoil removal and management, tooling changes, casing work where the ground requires it, rebar cage handling and setting, securing open shafts, and the rig’s lifting in service of the hole under its capacity and stability charts. Operations here is a manufacturing process performed in dirt, and the domain examines its sequence and its judgement points.
Technical Knowledge — ~31%
The machine and ground science: kelly bar, crowd system, mast, and rotary; hydraulic and mechanical drives; torque and crowd relationships and what they report about the ground; spoil character as information; shaft stability and the area of influence; capacity and stability charts; and the rig’s safety systems. At 31% this is the second-largest domain, and it examines understanding rather than procedure – why the machine and the ground behave as they do.
Tooling — ~4%
The smallest domain and the most distinctive: the tooling vocabulary of foundation drilling – augers of the types the ground dictates, buckets, core barrels, casing and its handling equipment, and the selection logic that matches tooling to soil and rock. Four percent of the sitting is a handful of questions, and they are the questions an outsider cannot guess.
Communications — ~8%
Communications examines the crew process: signals and radio discipline over a loud machine, the communication structure of the JHA and the pre-job briefing, cage-setting coordination between rig and crew, and the stop-work communication culture the foundation industry formalises. In a process worked by a small crew around rotating tooling, communication is a safety system, and the outline weights it as one.
Who this certification serves
Drill rig operators staff the drilled shaft industry: foundation contractors for bridges, high-rises, transmission structures, and heavy civil works, often travelling with rigs between regional projects. The crew is small – operator, and hands managing tooling, spoil, and cages – and the work is production-measured in feet drilled and shafts completed to specification. The program’s development with the ADSC, the foundation drilling industry’s association, gives the credential its trade standing; employers read FDR as examined evidence in their own process vocabulary, from JHA to tooling to shaft security.
The written route, in order
The written route mirrors the mobile program’s architecture: a Core examination – 90 questions in 90 minutes – and the FDR specialty – 45 questions in 45 minutes – with a calculator permitted on the drill rig written examinations, in either order. The practical examination on a foundation drill rig must also be passed, all elements within 12 months of each other, and certification then runs five years. A sibling specialty, AMP, shares the Core for a neighbouring machine family; the FDR route is this guide’s subject. Results issue under CCO’s criterion-referenced scoring with no percentage passing standard published. CCO’s written fees are $140 for the Core and $80 for the specialty under the fee schedule effective January 1, 2024.
What makes this examination demanding
The specialty is short – 45 questions in 45 minutes – and it applies a five-domain outline at specialty depth, so each question carries weight and the tooling and communications tails cannot be treated as decoration: together they are roughly an eighth of the sitting. The Core, at 90 questions, is the batch’s longest single sitting alongside its mobile namesake, and its technical block examines ground and machine science that operators who learned by feel must formalise: torque and crowd relationships, stability and capacity charts, and the JHA discipline as an examined method rather than a morning form.
The credential at work
The certified drill rig operator’s working value is shaft quality at production pace: holes to depth and plumb, spoil and slurry managed, cages set without incident, open shafts secured so the site is safe overnight, and a JHA habit that prices each site’s ground and neighbours before the rotary turns. The credential certifies that discipline for an industry where the product is buried and defects surface late and expensively. Its holders carry a certification written with their industry’s association, in their process’s terms, portable across the foundation contractors who recognise it.
What the PassProfessor program will cover
Original practice material, written to CCO’s published outline. The program is being built from scratch against the CCO Drill Rig Operator Candidate Handbook (REV 01/25) written examination outline for the CCO Foundation Drill Rig specialty examination: every practice set is organised by the outline’s own domains and weighted the way the outline weights them. No practice item is an actual examination item, and none is drawn from another provider’s material; items are written as the working decisions of a foundation drill rig operator – a described site, a machine in a stated configuration, a chart in front of you, a choice among plausible readings of it.
The certification around the exam, not only the sitting. Passing the written examination is one step in CCO certification, and it sits alongside a practical examination on a foundation drill rig and continuing compliance with CCO’s Substance Abuse Policy and Code of Ethics. Preparation that drills items while leaving the route unmapped produces candidates who pass the written sitting and then stall; this program keeps the whole route in view while keeping its centre of gravity on the written examination itself.
Results you can read by outline domain. Practice is reported domain by domain against the outline, so a candidate who is strong on operations and thin on tooling knowledge can see the split while there is still time to repair it, instead of discovering it in a score report.
Written examination only, stated plainly. This program prepares candidates for the written examination. It does not prepare candidates for the CCO practical examination, it includes no hands-on component, and no part of it substitutes for time on the machine. PassProfessor is an independent preparation provider, not affiliated with CCO (the National Commission for the Certification of Crane Operators, NCCCO) or with OSHA. The program confers no certification, no credit, and no exemption; CCO alone certifies.

Leave an email address and PassProfessor will write to you when the program is ready — and only about this program. No date is promised, because the program will open when it meets the standard described above, not before.
Frequently asked questions
Does this program cover the CCO practical examination?
No. It prepares candidates for the written examinations – the Drill Rig Core and the FDR specialty. Certification also requires a practical examination on a foundation drill rig, for which this program offers no preparation and no hands-on component.
How many written examinations does FDR require?
Two: the Drill Rig Core examination, 90 questions in 90 minutes, and the FDR specialty examination, 45 questions in 45 minutes. They may be taken in either order, and both – with the practical – must be passed within 12 months of each other.
What is the ADSC’s role in this designation?
The Drill Rig Operator program was developed with the ADSC – the International Association of Foundation Drilling – the industry’s association, which is why the outline speaks the trade’s language: job hazard analysis, tooling, spoil, cages, and shaft security.
How long is FDR certification valid?
Five years, under the current CCO Drill Rig Operator Candidate Handbook, whose recertification provisions include an experience measure for drill rig work.
What does CCO charge for the written examinations?
Per the CCO fee schedule effective January 1, 2024: $140 for the Core written examination and $80 for the FDR specialty written examination – CCO’s third-party fees for its own examinations.
Is there a percentage passing standard?
CCO publishes none for these written examinations; results are determined under CCO’s criterion-referenced scoring. Any percentage quoted elsewhere is not CCO’s.
Is PassProfessor affiliated with CCO?
No. PassProfessor is an independent preparation provider, not affiliated with CCO (the National Commission for the Certification of Crane Operators, NCCCO), the ADSC, or OSHA. The program confers no certification and reports nothing to CCO.
What is a job hazard analysis in this outline?
The structured pre-job analysis of the site’s hazards and controls that the handbook names as content in the pre-operations domain. It is examined as a method – candidates should be able to build one for a described site – not merely as a form a company keeps.
Why do the examinations permit a calculator?
Because the drill rig outline includes capacity and stability computation alongside its process material. The calculator is permitted on the drill rig written examinations, Core and specialty, per the handbook.
What is tooling, as a domain?
The cutting and handling equipment the rig turns: augers, buckets, core barrels, casing, and their selection against ground conditions. It is only about 4% of the outline, and it is the domain least guessable from general machinery experience.
