Re: "Public schools" in Pakistan?
Not sure what you are after - school that pays good salary? school with name / status ? Public school or school with good academic record?
Public schools were not made for academic results or to produce cadets - they were made for wadera's / sardars etc. The main purpose of them was to groom the kids from elite classes and teach them how to present themselves in public. Whilst at school, these kids meet other kids like them and make contacts that come in handy when they become MNAs / MPAs etc. As there are not many of these type of kids, they also take on normal kids (like me, I was at SPS). These normal kids get the good results to keep them in the top rankings! Back in the days of the Raj, they used to take on the English, all indian aristocracy and tribal sardars / waderas etc. The only true Public Schools in Pakistan are Aitchison, Lawrence College and Sadiq, although Sadiq was a late entrant built after the Raj, to cater for the "kala sahibs" of interior Sindh, Southern Punjab and baluchistan.
On the other hand, schools like KGS, St Patricks and all the convents were made by Christian priests to cater for the English kids and promote christianity. They were built in urban centres. These days their main purpose is academic excellence and therefore they have very high standards and are difficult to get into. However they do not have the acres of land the Public Schools have and therefore do not have all the facilities.
Then you have the modern schools such as City Schools, Beaconhouse etc. Totally commercial , however some branches have very high standards. They are catching up with the old dinosaurs as they use modern methods and normally copy their syllabus from UK / US.
As far as Sadiq Public School is concerned, it is a great school. It is huge - the largest in Pakistan. It has tennis courts, squash courts, horse riding, swimming pools, cricket, hockey and football pitches, 5 boarding houses, a separate girls' campus, junior school and senior school, hospital, mosque, library, shops, tailors, hair dressers, most of the teachers live within the school walls and then there is agricultural land leased out as well ! I think it is spread over 450 acres. It is true that it is full of rich kids but it has normal kids as well. Only problem is that Bahawalpur is not your Karachi / LHR / ISB type of city.
