From https://www.plai.org/ https://www.plai.org/ > PLAI is designed for upper-level courses that introduce the main ideas of programming languages. In the US, it is designed for students in their second- through fourth-years of college, as well as starting graduate students. However, PLAI has been used with students much younger, including in a few select high school classes.
