There is one school within Carthay's boundaries—Carthay Center Elementary, a K–6 school at 6351 West Olympic Boulevard.[8][9] Starting in Fall 2014, Carthay Center Elementary became Carthay School of Environmental Studies Magnet, a residential full-school magnet. Spaces are reserved for students in the traditional attendance boundaries, but the school is also open to magnet school applicants from throughout LAUSD.[10] The Environmental Studies program will be building on programs such as the celebrated Garden Science program at the school.[11]
