Grid technologies are more and more used in scientific as well as in industrial environments but often documentation and the correct usage are either not sufficient or not too well understood. Comprehensive training with hands-on experience helps people first to understand the technology and second to use it in a correct and efficient way. We have organised and run several training sessions in different locations all over the world and provide our experience. The major factors of success are a solid base of theoretical lectures and, more dominantly, a facility that allows for practical Grid exercises during and possibly after tutorial sessions.
