When a child joins a Japanese elementary or junior high, the grade is
set by age. The Ministry of Education's guidebook for foreign children
says children born from 2 April through 1 April of the next
year are in the same grade. The grade may not match the grade the child
was in before.
The same page says there is no system for skipping a grade in
elementary school, junior high, high school, or a special-needs school.
A child moves up one year at a time from the year they entered.
If Japanese is not yet enough and the curriculum for that age is not
suitable, the guidebook says the child may be placed in a lower grade
for a time. Some areas change the assigned school so the child can
receive Japanese-language instruction. If a disability is part of the
decision, the guidebook says to consult the municipal board about a
special-needs school or a special class. This article cannot make that
decision.
The municipal board of education is the place to ask before the child
starts. The notice of the assigned public school is a separate paper
from the ward.
