The ISOTDAQ 2015 is the sixth of a series of International Schools dedicated to introduce MSc and PhD students to the "arts and crafts" of triggering and acquiring data for physics experiments. The main aim of the school is to provide an overview of the basic instruments and methodologies used in high energy physics, spanning from small experiences in lab to the very large LHC experiments, spotting the main building blocks as well as the different choises and architectures at different levels of complexity. About half of the school time will be dedicated to laboratory exercises where the students are exposed to most of the techniques described in the lectures. http://www.cbpf.br/isotdaq
