This article aims to find ways to support a learner in a holistic manner, applying Myers-Briggs Typology Indicator (MBTI) as a methodological tool to facilitate learning process by considering learner individualities. Suggestions how to use MBTI in short-term courses of adult training, concentrating on feedback, performance, communication needs are made, based on the results of a study conducted among participants of the voice training. As the MBTI results can be understood and grouped in several ways, this study also compared the results with 3 different versions: Hanson & Silver (1995), Schroeder (1993) and Keirsey & Bates (1978, 1998) findings. Results were found matching most to the findings of Hanson & Silver (1995). This study reveals the typology of learners as Introverts and Extroverts, Analytical Thinkers, Social-Reflective Feelers and Holistic Visionaries. Although the research gives only preliminary conclusions, it gives certain recommendations how to approach different learners during the learning process.
