Brazil has recently gone through changes in school grades. Currently, at the age of 6 children attend from the grade 1 to 4 what is called Ensino PrimÃ¡rio (Portuguese for Primary Teaching, or Primary School), and afterwards from grade 5 to 9 the Ensino Fundamental (Fundamental Teaching/School).
Primary school usually begins at Year 1 (5 or 6 years old) and ends at Year 8 (11 or 12 years old). The last two years of primary school (Years 7 and 8) are often taken at a separate middle school, which is called an âIntermediate schoolâ in New Zealand.ew Zealand offers world leading education at secondary level. Secondary school study is usually five years long, from Year 9 (12 or 13 years old) to Year 13 (17 or 18 years old).
