This thesis was created as a learning diary of an eight-week period, at which point the author works as assistant coach in Tappara B2 (U17) team. The author has been working in Tappara and with this current team since May 2019. The current job is analysed and the different aspects of being an ice-hockey coach specified. The actual diary follows the daily life at the start of the competitive season. The diary is written on a daily basis including all practises, games and other events of the team. The diary includes weekly analysis on the aspects of planning and implementation, communication, goal setting, load management, growth mindset, testing, team cohesion, and the coaches resources. Firstly, the main observations during this 8-week period include my own development as a coach, based on literature and experiences. Secondly, on the basis of constant development of the players and team throughout the observation period. During the 8-week observation period I developed my own skills and working methods regarding delegation, communication, and identifying people’s strengths and weaknesses. I also increased my knowledge in physical and on-ice training for this particular age group, by researching new materials. Coaching is a life-long pursue for development and this 8-week observation period is a short period. Analysing learnt skills and new methods are important for the future of my professional career. In the discussion part of the thesis, a conclusion of the season so far is included, and the development needs discussed comprehensively.
