Argentina
Home room is a concept that does not exist in Argentinian schools, as a single classroom is often used for all assignments (except for lab work or outdoors exercise). Students usually stay in groups of 20 to 40 for at least 2 years without being reshuffled and often maintain the same grouping throughout both primary and secondary education, with only the group's room and assigned member of staff changing. Typically, Argentine schools will have a 15-30 minute form period in the morning, a one-hour period for lunch, and a similar period after lunch, albeit not all schools are required to have classes in both the morning and the afternoon. Schools (particularly private ones) will often use classes in the afternoon for secondary languages (English, French, etc) and sports activities. Students are usually not given much choice in the subjects they study and they all are subject to most academic subjects. The main choice a student has to make in entering secondary high school is in deciding a high school that leans towards general knowledge ("bachillerato", which encompasses arts and a general overview of science), economics ("commercial", whose orientation is towards math, primarily oriented towards accounting and business) or engineering (whose orientation is towards the sciences). Each school is given a lot of latitude in terms of extracurricular activities (teaching of secondary languages, sports, etc). Argentinian's education is often in flux, as governments every 5 years or so change the curriculum and number of required classes.
