No experience is necessary, but there a few things you must have in order to get into Picademy. First, you have to be a professional educator. Next, you will need to fill out an application explaining where you are an educator and at what level you teach. The rest of the application will ask questions ranging from your knowledge of the Raspberry Pi to why, exactly, should they pick you to attend Picademy. Remember, only 40 participants will be selected to attend, so make sure to put down all your contributions to education, including side projects and meetups, to show why you would make an excellent participant at Raspberry Picademy USA.
