PISR was initially established in 1966, with the strength of only six students in a rented villa of Shara-e-Khazan. It was started by five families of Pakistan Air Force officers who were keenly interested in the future of their generations. It got shut down after few months due to certain legal formalities but it didn’t stop them to keep struggle going.
The school was re-established with 28 students on 10th of January 1968, under the supervision of Pakistan Air Force. Mr. Toor was appointed as the Principal of the School.
The school was formally approved as an International Community School on 5th of January 1970 with the effort of prominent community members. This was the relentless contribution of His Excellence Dr Fazal ur Rehman Shiekh, Dr. Nasim Ghani and the Officers of Pakistan Armed Forces serving in Kingdom of Saudi Arabia. The School was allocated to Nasriya in 1972 and Mr. Mohammad Amin was assigned with the duties of Principal of the institution. The School remained under the supervision of Pakistan Armed Forces till 1987.
In 1987, the name of the school was changed on the recommendation of President of Pakistan. In 2001, it went under the supervision of Embassy of Pakistan with the name Pakistan Embassy School, Riyadh.
In 2001, the Ministry of Education KSA directed the school for the formation of School Management Council. It consisted of seven parents for the tenure of three years to look after the school affairs.
