Mexican schools have 12 grade levels. Grade 1 to 6 is meant for primary education where most students are aged between 6 and 12 years, while secondary education comprises of grades 7 to 12, according to Classbase.
Primary education is viewed as the basic part of education which every Mexican is entitled to learn. Consequently, it was made free by the Secretariat of Public Education. Secondary education consists of lower and upper education. Lower education consists of grades 7 through 9, while upper education has grades 10 through 12. At lower level, students can choose between following an academic path or a technical one. Those who choose the academic path continue with the upper education, while those who choose the technical path join vocational schools, as explained by Classbase.
