Prepare for the Mississippi Underground Utilities Contractor exam with a structured combination of Live Virtual + Self Study Training designed around the technical subjects and reference materials used for this Mississippi contractor examination. This program is built for candidates pursuing the Underground Utilities specialty classification through the Mississippi State Board of Contractors and who want an organized approach to exam preparation.
The Mississippi Underground Utilities classification covers water, sewer, and gas pipeline installation along with excavation, grading, and paving. The classification also includes directional drilling, auger boring, jacking and boring, trenchless technologies, wet and dry taps, grouting, and slip lining. Because this work combines pipeline installation, excavation, safety, welding, gas systems, and Mississippi underground-utility regulations, candidates need to prepare across several technical areas.
The Live Virtual + Self Study Training format gives candidates two complementary ways to prepare. Live virtual instruction provides scheduled, instructor-led review that can be attended remotely, while self-study training gives students the flexibility to reinforce the material between sessions, practice using technical references, and spend additional time on subjects that require more attention.
The training is organized around important references for Underground Utilities preparation, including Code of Federal Regulations - 29 CFR Part 1926 (OSHA), Installation Guide for Ductile Iron Pipe, Concrete Pipe and Box Culvert Installation, Pipe and Excavation Contracting, the State of Mississippi Regulation of Excavation, Chapter 13 Regulation of Excavations Near Underground Utility Facilities, ASME Code for Pressure Piping - B31.8 - Gas Transmission and Distribution Piping Systems, 2018, and Pipe Welding Procedures, 2003.
Because the examination is open book, effective preparation should include both trade knowledge and reference-navigation practice. Candidates need to recognize whether a question concerns ductile iron pipe, concrete pipe, excavation, OSHA safety, gas distribution, welding, or Mississippi One-Call requirements and then know which reference is most likely to contain the answer.
The live training schedule is organized around the books and technical references used on the exam.

The Mississippi Underground Utilities examination is administered through PSI as part of the contractor licensing process overseen by the Mississippi State Board of Contractors.
The current examination contains 50 questions. Candidates are allowed 2 hours to complete the test and must earn a minimum score of 70 percent to pass.
The current exam content outline includes:
Concrete pipe installation and ductile iron pipe installation are the two largest individual subject areas, with nine questions each. Underground utility gas systems follow with eight questions, while excavation and grading account for another seven. These subjects should receive substantial attention during preparation.
Safety is also a dedicated examination area. Underground utility work can involve trenches, excavations, heavy equipment, lifting, traffic conditions, confined work areas, tools, welding, and other jobsite hazards. Candidates should understand how OSHA construction standards apply to these operations.
The Mississippi One-Call portion tests knowledge associated with excavation near underground utility facilities. Contractors working below grade must understand the responsibilities involved in planning excavation, coordinating utility-location procedures, protecting marked facilities, and responding appropriately when underground infrastructure is encountered.
The Mississippi Underground Utilities Contractor examination is an open-book test. PSI permits candidates to bring approved reference materials into the examination center under current testing rules.
Candidates are responsible for bringing their own references. Approved books may be highlighted, underlined, and indexed before the examination. Permanent tabs are permitted for organizing the references. Temporary removable tabs, including Post-it-style tabs, are not allowed.
Candidates may not write in the approved references during the examination. Additional loose or attached papers are also prohibited. PSI permits a silent, nonprinting, non-programmable calculator in the testing center.
PSI states that non-code references may be used in earlier or later editions, but candidates assume the risk of differences between editions. Candidates should become familiar with the versions they intend to use and understand that wording, tables, illustrations, or technical recommendations can change between editions.
Open-book testing does not remove the need to study. With 50 questions in two hours, candidates have an average of approximately 2.4 minutes per question. Efficient preparation means knowing which reference to use before beginning a search.
During practice, identify the question type first. A trench-safety question may lead to OSHA, a ductile pipe question to the Installation Guide for Ductile Iron Pipe, a gas-system question to ASME B31.8, and an excavation-notification question to Mississippi's underground utility regulation.
The Mississippi State Board of Contractors regulates the Underground Utilities specialty classification. Candidates must complete the applicable commercial contractor licensing process in addition to passing the required examination.
The Mississippi State Board of Contractors defines Underground Utilities as a specialty classification involving water, sewer, and gas pipeline installation along with excavation, grading, and paving.
The scope also includes directional drilling, auger boring, jacking and boring, trenchless technologies, wet and dry taps, grouting, and slip lining. This broad scope explains why the examination combines pipe installation, excavation, gas, welding, safety, and state excavation regulations.
Underground Utilities is identified by MSBOC as a tested specialty classification. Applicants who pursue this classification must complete the application process and satisfy the examination requirements established for the license.
The Mississippi commercial contractor application requires the applicant to designate a qualifying individual for required testing. Proof of employment for the qualifying individual is part of the Board's qualification process.
New applicants receive examination eligibility through the Board. Once eligibility is established, PSI provides the information needed to proceed with testing. Candidates should coordinate application preparation with their technical study so that progress in one area does not unnecessarily delay the other.
Applicants pursuing Underground Utilities should also understand the importance of Mississippi excavation regulations. Work performed around existing underground facilities requires coordination and compliance with state requirements designed to reduce damage to buried infrastructure and protect workers and the public.
Begin preparation with concrete pipe and ductile iron pipe because these two subjects account for 18 of the 50 examination questions. Candidates should understand how trench conditions, bedding, alignment, joints, handling, installation procedures, backfill, and compaction affect underground pipeline construction.
For ductile iron pipe, practice using the Installation Guide for Ductile Iron Pipe to locate technical information efficiently. Become familiar with its organization and the terminology used to describe pipe, joints, trench preparation, handling, and installation.
For concrete pipe, review installation procedures from excavation through final backfill. Understand how proper bedding and support influence pipe performance and how field installation practices affect the completed underground system.
Excavation and grading account for seven questions. Use Pipe and Excavation Contracting alongside OSHA to review trenching, excavation, equipment, soil and site considerations, grading, pipe placement, backfilling, and jobsite procedures.
OSHA safety should receive dedicated study time. Excavation work can present serious hazards, so candidates should become familiar with the construction safety requirements that apply to trenches, access and egress, protective systems, equipment, hazardous conditions, and worker protection.
The gas portion includes eight questions and should be studied with ASME B31.8. Review terminology, gas transmission and distribution piping concepts, materials, construction practices, joining, testing, operation, and other topics relevant to underground gas systems.
Welding accounts for four questions. Pipe Welding Procedures can help candidates review pipe preparation, welding terminology, joint configurations, welding techniques, and field procedures associated with pipeline construction.
Mississippi One-Call accounts for three questions. Study the state excavation regulation carefully. Candidates should understand the responsibilities that exist before excavation begins and the requirements intended to protect existing underground facilities.
Use active reference practice rather than only reading. Choose a subject from the exam outline, identify the appropriate reference, and locate the applicable information. Then repeat the process using another topic. This develops the same decision-making process needed during an open-book examination.
Timed practice is also important. With only two hours for 50 questions, candidates should learn when a reference lookup is necessary and when trade knowledge can provide the answer more efficiently. Developing that balance can help preserve time for more complex technical questions.
Live virtual training gives Mississippi Underground Utilities candidates a structured way to work through the examination topics while participating remotely. Scheduled training can help create consistency across a test that covers several distinct technical areas.
The live format allows candidates to follow organized instruction while working with their technical references. When ductile iron pipe, concrete pipe, gas systems, excavation, welding, OSHA safety, or Mississippi One-Call requirements are discussed, students can connect the subject directly with the appropriate reference.
Live instruction works best when followed by independent practice. After a topic is reviewed, return to the applicable book and practice locating the information without relying on class notes alone.
Self-study training gives candidates flexibility between live sessions. Underground utility contractors may come into the course with different strengths. Someone with extensive excavation experience may need more time on gas systems or welding, while another candidate may need additional work with ductile iron or concrete pipe installation.
Independent study allows preparation to be adjusted around those needs. Candidates can review difficult subjects repeatedly, practice using the references, and work through exam-style questions under timed conditions.
The objective is active preparation. Rather than reading every book from cover to cover, study by topic, locate the supporting material, and practice applying it to realistic underground utility questions.
Contractor Exam Prep helps Mississippi Underground Utilities Contractor candidates organize preparation around the actual trade subjects represented on the examination.
The Live Virtual + Self Study Training format combines structured instruction with flexible independent review. Candidates can build familiarity with concrete pipe, ductile iron pipe, gas systems, excavation, grading, welding, safety, and Mississippi underground utility regulations.
Contractor Exam Prep emphasizes practical reference navigation for open-book examinations. Candidates should learn how each reference is organized and practice identifying which book is most useful for a specific question.
Trade-focused review also helps connect technical references with real construction work. Understanding why a particular installation or safety procedure matters can make technical material easier to apply during the examination.
The goal is to provide organized study guidance, underground-utility-focused review, practice-oriented preparation, reference navigation, and a confidence-building study structure that helps candidates approach the Mississippi Underground Utilities Contractor exam with greater direction.
