DPLI Screening case studies
DPLI Screening · Put your knowledge to work in context.
The DPLI Screening assessment is a multiple-choice exam used to evaluate whether a candidate has the foundational knowledge expected of someone working in pipeline, utility, or industrial inspection and integrity roles. It is typically taken by people entering the field, by technicians moving from general maintenance into inspection work, or by experienced staff who need to demonstrate baseline competence before advancing to more specialized certifications. The exam is organized around five domains: safety and regulatory knowledge (25%), inspection and testing procedures (25%), equipment and system fundamentals (20%), documentation and recordkeeping (15%), and professional conduct and ethics (15%). Because the weighting favors safety and hands-on inspection method, candidates should expect a mix of scenario questions that ask what to do next, which test or tool applies, and how to record a finding correctly. The DPLI Screening case studies are 5 cases and about 2,420 words.
