The results of the development of a new computer guidance method for senior schoolchildren on the basis of “Formulas of the profession” (E.A. Klimov) and a modern scheme for the analysis of professions (N.S. Pryazhnikov) are presented. The main stages of obtaining expert estimates are shown, which made it possible to correlate the components of professional activity with the official list of enlarged specialties of the Ministry of Education and Science of the Russian Federation. The advantage of 3-level grades of schoolchildren (“I want”, “I can now” and “could in the future”) is considered before the traditional assessment of schoolchildren’s actual preferences. In the process of choosing a profession, the preferred characteristics of future work activity are set not in the form of direct estimates of their traditional designations (subject, purpose, means, conditions, etc.), but through paired comparisons of the main labor activities and training activities. The computer-based online testing system works with the methodology through the Web-interface on modern software platforms — Windows, Android, MacOS, iOS, Linux.

The article explains the continuity of domestic proforientational methods, DDQ and «Proforientator». The authors described the scientific and organiziational contributions, made by Professor E.A. Klimov in the development of modern proforientational diagnostic methods. The reader of this article can find the illustration of his contributions to the history of emergence of a computerized test «Proforientator» and the logic of its revising. The authors focus on the block «interests» and secondary scales of modern test in the areas of targeted learning. Analysis of massive empirical material using expert assessment and mathematical statistics, allowed to reasonably prove validity of schoolchildren’ test results with the help of the «Proforientator» test real career, with a precision of up to six areas of targeted learning. Also it was given attention to deal with individual bright cases involving real failed choices of higher education and specialty. The materials described the theoretical basis of domestic proforientational approach, which have been tested in practice.
