Every school offers a different range of subjects at Standard Grade.
Some schools might also offer the chance to study National Qualification units in S3 and S4. So check with your teachers to find out what you can do at your school and how many subjects you have to choose. Check in the Job File booklet and try visiting your school careers library - you'll find more information about jobs and the qualifications you need. Standard Grades come under the group of qualifications called National Qualifications. These also include the new qualifications developed under the Higher Still programme and which you will go on to study after Standard Grades.
