The program App-rentice is about organization of series of 8 hackathons in 8 Bulgarian cities. The hackathons will be for students in the secondary schools from 5th grade until 12th grade at the age between 10 and 19. Our team will identify the appropriate schools and the teachers that will act as coordinators and promote the hackathons inviting the students for participation. The topics for the hackathons will be broadly defined allowing choice of technologies, programming languages and software platform that could be utilized. An example for topic is ‘An application for the citizens of Haskovo and for the business of the city’. We will invite mentors with good technical skills who will support the students in the development of their prototypes. The hackathons will have a duration of one weekend and on the last day the teams will present their prototypes in front of jury and the winners will be announced and awarded. The organizer will provide drinks, food, fast internet and electricity.
