The Salt School for Boys has played a leading role in the political and scientific advancement of Jordan. Since its establishment date this learning institution had graduated allot of Jordan's leading personalities and prominent figures including: prime ministers, ministers and businessmen too.

The school was established in 1918, but it was not until the year 1919 that it had actually started offering classes. Its classes were first conducted in some of the city's homes, but as the demand for these classes increased the school's administration was forced to move its operations to an independent facility. This independent facility was built through the generous donations of the city's inhabitants, and until this day the school is named Al-jadoor in reference to the Al-jadoor Hill where it was originally built.

Due to the fact that the Salt School for Boys was the only school operating in the kingdom allot of its students and teachers came from outside the city. Its students came from different parts of the country and its teaching staff came from Syria, Lebanon, and Egypt. To accommodate these people the school premises encompassed a dormitory, which remained functioning until the year 1929.

The school's Library was established between the years 1926 and 1927, and in the year 1956 a second floor was added to it. Its exterior walls were made out of yellow stone. The library building was recognized for its simplicity. Its first floor windows were horizontal, and its second floor windows were rectangular with steal shutters. Its roof held a stone pillar, which was perfectly situated to hold the Jordanian flag.
