Gender dimension in training practices can not be appropriately understood besides the cultural and social environment in which a trainer is practicing. Being women or men in a professional training area could vary often in relation to different factors: culture regarding the role of trainer, the trainer status into society, organizational model of the institutions providing training, general perceptions, expectations and practices on gender issues in different societies. Although many VET research papers take into consideration the gender factor in analysing training profiles, achievements or performances, gender dimension in training practices is rather implicit in most of them. Apart of the interest in looking at specific contexts with the aim of making proposals for appropriate professional development frameworks for trainers, the LEONARDO Project TTPlus takes explicitly the task to identify the gender features in training practices in different countries, proposing also a specific research methodology for looking deeper on gender dimension. The symposium synthesizes the research methodology and outcomes around the topic of gender in professional development and practices of trainers at the workplace.
