Grade point average

Grading in education is the process of applying standardized measurements of varying levels of achievement in a course. Grades can be assigned as letters (generally A through F), as a range (for example 1 to 6), as a percentage of a total number of questions answered correctly, or as a number out of a possible total (for example out of 20 or 100).

In some countries, all grades from all current classes are averaged to create a grade point average (GPA) for the marking period. The GPA is calculated by taking the number of grade points a student earned in a given period of time of middle school through high school. GPAs are also calculated for undergraduate and graduate students in most universities. The GPA can be used by potential employers or educational institutions to assess and compare applicants. A cumulative grade point average is a calculation of the average of all of a student's total earned points divided by the possible amount of points. This grading system calculates for all of his or her complete education career. Grade point averages can be unweighted (where all classes with the same number of credits have equal influence on the GPA) or weighted (where some classes are given more influence than others).

Yale University historian George W. Pierson writes: "According to tradition the first grades issued at Yale (and possibly the first in the country) were given out in the year 1785, when President Ezra Stiles, after examining 58 Seniors, recorded in his diary that there were 'Twenty Optimi, sixteen second Optimi, twelve Inferiores (Boni), ten Pejores.'" Bob Marlin argues that the concept of grading students' work quantitatively was developed by a tutor named William Farish and first implemented by the University of Cambridge in 1792. Hoskin's assertion has been questioned by Christopher Stray, who finds the evidence for Farish as the inventor of the numerical mark to be unpersuasive. Stray's article elucidates the complex relationship between the mode of examination (testing), in this case oral or written, and the varying philosophies of education these modes imply, to both the teacher and student. As a technology, grading both shapes and reflects many fundamental areas of educational theory and practice. Over the past hundred years, various colleges, such as Evergreen State College and Hampshire College have begun to eschew grades. Ivy League university Brown University does not calculate grade-point averages, and all classes can be taken on a pass/fail basis. Additionally, several secondary schools have additionally decided to forgo grades. A notable example is Saint Ann's School in Brooklyn which was ranked by the Wall Street Journal as the number one high school in the country for having the highest percentage of graduating seniors enroll in Ivy League and several other highly selective colleges.
