Elementary school is the first level of school for American children.  It's called primary school in many other countries.
I guess it's the same across many other countries too
In the United States, after elementary school, kids go to middle school, which used to be called junior high.
I see, in the south east Asian countries it's called secondary school. Logical progression from Primary to Secondary
That makes sense!  The ages of students at primary and secondary school can vary even within countries.
Well, again going back to the region i belong to, i can say the ages don't vary much. Quite unlike in the west i guess.
Oh interesting. Does your country have a good basic education system?
Unfortunately no. It doesn't.
Education in China
Education in China is a state-run system of public education run by the Ministry of Education. All citizens must attend school for at least nine years, known as the nine-year compulsory education, which is funded by the government. Compulsory education includes six years of primary education, starting at age six or seven, and three years of junior secondary education (junior middle school) for ages 12 to 15. Some provinces may have five years of primary school but four years for junior middle school
and middle school are considered basic (obligatory) education. These are "Primaria" (6-12 years old), which is the Spanish equivalent of elementary/primary school, and "Secundaria" (12-16 years old), which would be a mixture of middle school and the first two years of High school in the United States/secondary school in England and many other countries.
Spain is working towards reforming vocational education and modernizing education to halt and reverse the rising unemployment rates.
