The GCSE grading system in England, Wales, and Northern Ireland runs on a scale from 9 to 1, with 9 being the highest grade and 1 being the lowest. This new grading system was introduced in 2017, replacing the old GCSE grading system that awarded students letter grades from A* to G. The U grade, meaning "ungraded", remains the same. The highest grade is now 9, while 1 is the lowest. The reformed GCSE qualifications are awarded on a grade scale of 9 (the highest grade) to 1 (the lowest) . The new scale is aligned to key grades on the current A* to G scale. For example, broadly the same proportion of students will achieve a grade 4 and above as currently achieve a grade C and above, and broadly the same proportion of students will achieve a grade 7 and above as currently achieve a grade A and above.
