Jabal Amman
Established in 1957, NOS was the first co-educational school in the country. Operating out of a rented building in the Jabal Amman, they began with only 70 students and four teachers in three grades (KG1 - Grade One). In 1965, they moved to their permanent premises in the Shmaisani area of West Amman, and they continued to grow until they celebrated their first graduating class in 1972. Today, the school's population has grown to around 2400 students (from KG1 – Grade 12), with more than 360 staff members.
