Introduction. The growing shortage of personnel in industrial enterprises necessitates a review of the internal training system. In the current circumstances, it is imperative to leverage internal resources – highly skilled employees with rich practical experience and professional competence, for whom teaching is  not their primary or  regular activity. However, preparing them for teaching through lengthy additional professionalpedagogical education programs is  impractical. A  technology for short-term training is required, utilizing individual educational trajectories. 

Aim. Checking the effectiveness of the technology of short-term training of in-company teachers in industrial enterprises. 

Methods. This study aims to justify the effectiveness of short-term training technology for in-house instructors in industrial enterprises.. 

Results. Data obtained from the implementation of the short-term training technology for in-house instructors attest to  its effectiveness. The identified criteria for levels of  professional-pedagogical competence formation, considered when designing individual educational trajectories, contribute to the scientific novelty of the research. 

Practical significance. The proposed short-term training technology for in-house instructors, along with its organizational and pedagogical support, can be  utilized by enterprises and organizations across various industries.
