Standard Grades were Scotland's educational qualifications for students aged around 14 to 16 years. Introduced in 1986, the Grades were replaced in 2013 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.

Following the Munn and Dunning reports published in 1977, the Standard Grade replaced the old O-Grade qualification, and was phased in from 1986.

Standard Grade courses were taken over a student's third and fourth year in secondary education. Exams were taken at the end of the 4th Year (around May), with preliminary examinations taken several months earlier in November. (However, certain subjects may have been "fast tracked" at some schools (for example Dalziel High school, which was the first school to use this system), where the course is started in at the beginning of 2nd year and finished at the end of 3rd year (this meant that pupils start standard grades at age 12/13 and finish them at age 14/15). The exams were provided by the Scottish Qualifications Authority, which also offers the more recent National Qualifications on the Scottish Qualifications Certificate.

Students would typically study 8 subjects at Standard Grade. Generally speaking, different subjects could be taken independently of each other, although English and Mathematics were compulsory, and most schools would structure student choices so that at least one science subject, one social science (and often a modern language) were chosen. The two main restrictions on this choice were timetable arrangements, and the fact that many less popular subjects were not offered by all schools.

There are three sub-levels (or "tiered" papers) at which Standard Grade exams can be taken, namely "Foundation Level", "General Level" and "Credit Level". At one sitting, students generally sit either the Foundation and General level papers together, or the General and Credit level papers together.

Students are awarded a numerical grade for each examination (which may consist of several papers) ranging from 1 (best) to 7. The table below lists the grades, the exam level and equivalence to the new National Qualification exams and the Scottish Credit and Qualifications Framework (SCQF for short).

The Scottish Government Authorities responsible for Education decided to slowly phase out the Standard Grade system in favour of the Scottish Qualifications Authority's Higher Still system as many students and teachers felt that the jump from Standard Grade to Higher was too difficult, particularly in subjects such as English. Although they are not exactly the same, the Foundation Level is similar to Higher Still's Access 3 level, whilst General is similar to Intermediate 1 and Credit is similar to Intermediate 2.
