What is k12 in MAPEH?

In the Philippine MAPEH (Music, Arts, Physical Education, and Health) curriculum, K to 12 refers to the entire educational track from Kindergarten to Grade 12. It's not a specific subject *within* MAPEH, but rather the context in which MAPEH is taught. The MAPEH subjects are taught throughout those 12 years, adapting to the developmental stage of the students at each grade level.
