"Recess" has rather specific connotations in American English. It is not simply another word for "break". It connotes a supervised, semi-structured playtime for young children, generally outdoors, in the presence of teachers.
By the time one hits high school (9th grade) in the US, such things do not occur. You may have free time between classes, but it is not referred to or treated the same way as the period known as "recess".
