Development of a Classification Model for Adolescents' Vocational Guidance Profile and Creation of a Client-server Application

This work is devoted to creation of a vocational guidance service for adolescents, which includes testing technique improved by modern methods of mathematical statistics. The differential-diagnostic questionnaire of E. Klimov was used as the basis for developing a model of vocational guidance profiles for adolescents. Based on a survey of 192 high school students using an adapted version of the questionnaire, employing the method of two-step cluster analysis and preliminary classification with the exception of statistically insignificant variables, 13 new profiles were identified, instead of 5 from the standard technique. Interpreted by experts, these profiles will allow students to receive more detailed recommendations based on the questionnaire of E. Klimov. To provide testing services to students, was designed an information system which includes the user's mobile Android app, server side, and administrator's app. The user's application, written in Java, consists of self-generating interfaces that provide testing services, a personal account etc. The admin app allows psychologists to add new tests and download data for analysis without programming knowledge. The server part consisting of a database, REST architecture, and message broker is written in PHP and SQL and uses RabbitMQ technology. The developed system will be used by specialists of the «HR center No. 1» in Dmitrov to provide vocational guidance services to Russian schoolchildren.
