Bags There were 'Grammar' Schools in Scotland except they were called High Schools or Academies. The selection process was via the 'Control Exam' and there was not really a stigma in going to the 'Tech', in fact it was the few (5 from my class of 40) who went to the Academy who were mocked, declared 'posh', outsiders. The Academy was geared towards academic excellence with the expectation that pupils would attend for 5 or 6 years which meant that those of us (mostly girls) who left at 15 had no qualifications whatsoever and had to attend evening classes to take Os and Highers but mainly shorthand and typing (not taught at the Academy) in order to compete in the job market with our well trained sisters from the Tech.
By the time my DDs reached Secondary School age the comprehensive system was well bedded in and served both daughters well, giving them a broad education and self confidence. A bonus was that the Comp with its locality based intake was only 2 miles away, whereas the Academy, which served the whole county was sited on the periphery of the County Town requiring a bus journey and long walk for almost all pupils.
I am very glad that Ms May is not in charge of Education in Scotland. I am not sure she understands this as she keeps referring to the 'whole Country' and Britain. Unfortunately for those in England, when this legislation comes before Parliament it will be debated under EVEL rules, with NI, Welsh & Scottish MPs (mostly in favour of a Comprehensive system) excluded from the debate.
