HSOG meaning in Community ?

The High School of Glasgow is an independent, co-educational day school in Glasgow, Scotland. The original High School of Glasgow was founded as the choir school of Glasgow Cathedral in around 1124, and is the oldest school in Scotland, and the twelfth oldest in the United Kingdom. On its closure as a selective grammar school by Glasgow City Corporation in 1976, it immediately continued as a co-educational independent school as a result of fundraising activity by its Former Pupil Club and via a merge by the Club with Drewsteignton School. The school maintains a relationship with the Cathedral, where it holds an annual service of commemoration and thanksgiving in September. It counts two British Prime Ministers, two Lords President and the founder of the University of Aberdeen among its alumni.

It is a selective school, meaning prospective pupils must sit an entrance test to gain admission. In 2009 and 2017, The Times placed it as the top independent school in Scotland for SQA results.

The rector of the school is John O'Neill.
