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
Middle school
A middle school (also known as intermediate school, junior high school, or lower secondary school) is an educational stage which exists in some countries, providing education between primary school and secondary school. The concept, regulation and classification of middle schools, as well as the ages covered, vary between, and sometimes within, countries.
Afghanistan.
In Afghanistan, middle school consists of the primary school grades 5,6, and 7 and the secondary school grade 8.
Albania.
In Albania,
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.
