The minimum age is 8. In the past, we trialled various ages, such as six, but after assessing the quality and amount of content they could learn, we decided to enrol only students who were at least eight years old at the time of booking. We know some students start coding younger, but those are the exceptions. One of the aspects we discovered in practice was that younger students could not maintain their concentration for extended periods, so their attention span was too short for STEM class. The other issue was that they needed help comprehending some abstract notions, no matter how much we broke down the content. Therefore, after studying the results, we decided to offer our courses only to students at least eight years old.
