Grading in education is the process of applying standardized measurements of varying levels of achievement in a course. Grades can be assigned as letters (for example 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 (CGPA) is a calculation of the average of all of a student's total earned points divided by the possible number 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.
Most nations have individual grading systems unique to their own schools. However, several international standards for grading have arisen recently.
In the General Certificate of Secondary Education (GCSE) exam taken by secondary school students in England and Wales, grades generally range from 9 (highest) to 1 (lowest). However, in GCSE Science, Additional Science, Mathematics, Statistics, English Literature, English Language, and any Modern or Classical Foreign Language, there are two tiers (higher and foundation). In the higher tier, grades 9 to 4 can be achieved, while in the foundation tier, only grades 5 to 1 can be awarded. Generally, a 4 or above would be considered a pass and a 3 or below would be considered a fail by most institutions: for Mathematics and English Language and English Literature, and possibly Science, this would require a resit.
If an examined candidate does not score highly enough to get a grade 1, then he/she will be 'Unclassified'. This is often abbreviated to a 'U' as a final result.
Most colleges and universities in the United States award letter grades from F through A for each class taken. These marks are then used to determine an overall Grade Point Average (GPA) from 1.0 to 4.0, which is calculated using a formula. The average GPA is 3.3 at private institutions, and 3.0 at public ones.
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 high 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.
According to a study published in 2014, a one-point increase in high-school GPA translated to an 11.85% increase in annual earnings for men and 13.77% for women in the United States.
College and post-college students often wonder how much weight their GPA carries in future employment. In the various broadly defined professions as a whole, internships and work experience gained during one's time in college are easily the most important factors that employers consider. In order of importance, the remaining factors are choice of major, volunteering, choice of extracurricular activity, relevance of coursework, grade point average and the reputation of one's college. The relative importance of these factors do vary somewhat between professions, but in all of them, a graduate's GPA is relatively low on the list of factors that employers consider. There is also criticism about using grades as an indicator in employment. Armstrong (2012) claimed that the relationship between grades and job performance is low and becoming lower in recent studies. The grade inflation that has plagued American colleges over recent decades has also played a role in the devaluation of grades.
Different educational boards use different metrics in awarding grades to students, along with the marks obtained in most cases.
For example, Kerala state board uses a linear scale; A+ for a mark over 90%, A for a mark between 80% and 90% and so on .
However, the national board CBSE uses positional grades to indicate a student's position with the rest of their peers in that subject, and hence the cutoffs required to obtain a grade will differ with year and subject; however, the percentage of students receiving them will roughly be the same.
Ultimately, grade inflation has severe consequences. Not only does it make it difficult for employers to vet the caliber of an applicant, but it also misleads students, who often use their grades as benchmarks to help diagnose their strengths and weaknesses.
