GPA stands for ‘Grade Point Average’ and is a mathematical average of all grades received over a given period of time. It is commonly used in the United States and Canada, and in many international schools, and is one of the measures used by universities in North America to determine college acceptance. At NIS, in common with most schools who use GPA, it is accumulated over the course of the High School career meaning that the GPA of a student in Grade 12 is an average of their Grades from the first Semester of Grade 9. In order to calculate GPA, letter grades (from each final semester report) are turned into a number (A+=4.5, A=4, B+=3.5, B=3, C+=2.5, C=2, D+=1.5, D=1, F=0) and these numbers are averaged (equally weighted) into a final ‘grade point average’. GPA is valued by many people because it can be said to be an indicator of achievement over time (consistency) and for that reason, while universities do not require us to provide GPA, it is one measure which universities (particularly in North America) value. At NIS we currently also use GPA as the determining factor in the award of Valedictorian and Salutatorian. However, since it is an average score over time, it does not take into consideration students who have made exceptional progress in later grades, nor take into account that the GPA is a mathematical average of different grades, coming from different teachers in different classrooms. Therefore, GPA is only one method used at NIS to assess unique individual learners. The externally validated and moderated IB results, PSATs and SATs are also important measures of learning.
