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).
Under the Commissioner's Program, the school grade is a raw score of data and the sum of all the ratings for all indicators within each core element on the School Self-Assessment (e.g., 65 of 78 points). The maximum total score for a school is 78 points.
