Standard Grades were Scotland's educational qualifications for students aged around 14 to 16 years. Introduced in 1986, the Grades were replaced in 2013[1] with the Scottish Qualifications Authority's National exams in a major shake-up of Scotland's education system as part of the Scottish Credit and Qualifications Framework overhaul.
Scottish Standard Grades roughly matched the English, Welsh and Northern Irish General Certificate of Secondary Education examinations in terms of level subject content and cognitive difficulty.[2]
