Iranian academic year began on Saturday during an opening bell ceremony held in Tehran attended by President Rouhani.
Concurrent with the start of the new school year in Iran, 146 educational projects came into operation.
About 1,300,000 first grade students have started their school year.
Students in Iran go to school for 10 months a year, or about 200 active days, from September to June. The average number of students per classroom is 20. From ages 7 to 18, boys and girls are educated separately.
Beginning at age 7, all students must pass a yearly exam in order to move to the next grade level. Students in primary school learn about hygiene, basic math and science, reading, and study skills.
