Grade Boundaries
Edexcel GCSE
March 2013
Understanding Edexcel GCSE grade boundaries This document shows the grade boundaries for modular and linear GCSE qualifications. For each set of grade boundaries, the maximum number of available marks is also shown.
For modular GCSEs, maximum marks and grade boundaries for individual units are shown for both the raw and uniform (UMS) mark scales. Maximum marks and grade boundaries for the overall qualification (the ‘cash-in’) are only shown in UMS marks.
For linear GCSEs, only the overall maximum mark and grade boundaries are available. These are given in raw marks as UMS marks are not used in linear qualifications.
Where grade boundaries are greyed out for a particular unit, there are no grade boundaries available. This may be because:
● the unit was not available in this exam session ● no one took the unit in this exam session.
Definition of terms
A grade boundary is the minimum mark at which a letter grade can be achieved. For example, if the grade boundary for a B is 60 marks, then 60 is the minimum mark at which a B can be achieved. A mark of 59 would therefore be a C grade.
For modular qualifications, assessments can be taken in various exam sessions throughout the duration of the course.
For linear qualifications, all assessments must be taken in the same exam session.
A raw mark is the actual mark awarded by the teacher or examiner for an assessment. Raw mark scores can be downloaded by Exams Officers from Edexcel Online.
Raw marks are converted to UMS marks for all modular qualifications. This is because raw mark grade boundaries may change from exam session to exam session to take into account variations in the difficulty of assessments. A Certifying Statement of Provisional Results (results slip) will always show the UMS mark for modular qualifications.
You can find out more about raw and UMS marks at www.edexcel.com/results
