It is intended for exams officers and others with a reasonable understanding of the exam system and its terminology. |\n\nFor more information contact a member of the Centre for Education Research and Practice (CERP) [at](at cerp@aqa.org.uk)[ ](at cerp@aqa.org.uk)[cerp@aqa.org.uk](at cerp@aqa.org.uk)  \n1. Introduction  \nFor some years nearly all A-level, AS and GCSE specifications have used a uniform mark scale (UMS) . Uniform marks have also been used in many of our Level 1/Level 2 Certificates (iGCSEs) .  \nSpecifications which use uniform marks will continue to do so until they are withdrawn. However, uniform marks are not used in reformed A-level, AS and GCSE exams for first teaching in and after September 2015.  \nAppendix A contains tables showing the relationship between uniform marks and grades for our A-level exams and the GCSE sciences. For details for all other AQA GCSE exams, please refer to the uniform marks section of the AQA website ([aqa.org.uk/exams-administration/results-days/grade](aqa.org.uk/exams-administration/results-days/grade)boundaries-and-ums) .  \n2. Why we need the UMS  \nIn linear specifications, students take all papers in the same exam series. After scaling the raw marks to comply with paper weightings1 , students’ marks are added to give a total mark for the exam as a whole. Using the grade boundaries set by the awarding committee, subject grades are then allocated.  \nModular specifications, on the other hand, allow students to take the module/unit exams in different series. Papers for a particular unit may vary slightly in levels of difficulty. A mark of 45 in summer 2016, for example, may represent the same level of achievement as a mark of 48 in summer 2017. Some method must therefore be found to put the marks from different series on a common, or uniform, scale so that both 45 (from 2016) and 48 (from 2017) have the same value when contributing to an overall grade.  \nOne way of resolving this problem would be to award just grades to students for each unit. The grades could then be equated to points (for example: A=5, B=4, C=3, D=2, E=1 for A-level or A*=8, A=7, B=6, C=5, D=4, E=3, F=2, G=1 for GCSE) and each student’s points could be added to give him/her a points total for the subject as a whole.  \nThis points method would have disadvantages for A-level and GCSE qualifications, as it needs to be modified when the units are not equally weighted and gives the same credit to a student with a low mark in a particular grade as to one with a high mark in that grade. The UMS was developed to avoid the disadvantages of the points method, although the principle is the same.  \nFrom 2014 all GCSEs became linear. However, because the specifications were largely unchanged, they continue to use uniform marks until they are withdrawn. A-levels remained modular, and specifications introduced before September 2015 also continue to use uniform marks until they are withdrawn.  \nThe reformed GCSE, AS and A-level specifications, for first teaching in September 2015, September 2016 or September 2017 (depending on the subject), are linear. A UMS would have little purpose and would introduce unnecessary complexity. Therefore, the awarding bodies and Ofqual agreed that UMS would no [longer be used. Please see](longer be used.
