The International Register of Specialists and Experts (МРСЭ), presented on spec-expert.ru as the Register of Professionals, is an information system for organized records of scientists, specialists and experts. It evaluates candidates independently according to international standards and certification models, with accreditation reflected in the register. The site reports more than 480 specialists, over 100 professionals and over 100 experts across 15 participating countries and 28 Russian regions, and lists nine professional communities and associations.

The register’s services focus on candidate identification, applications, document review, competency assessment, classification and professional accreditation. Applicants submit information and supporting documents for a preliminary commission review. Candidates who pass may be entered in the register, assessed in relevant professional fields and categorized as professionals or experts based on evidence such as practical experience, further training, attestations and certificates. Accredited participants can also undergo independent professional assessment and certification, with the results recorded in the system. The register lists organizations connected with fields including construction, engineering, geology, seismology, geotechnics, urban planning and soil mechanics.
