Disadvantages of Grading System

School is revered to be the second home of many children. It plays an integral part in the holistic development of each and every student. Not only does it act as a medium in which children learn new things but they are exposed to the real world where they interact with their peers and learn many things through experience which nothing else can provide.

The primary reason for schools to exist in the world is to impart knowledge to the students studying in it and assessing the students forms an integral part of the functioning of the school which is usually carried out in two ways. 
The primitive type of assessment was by marks where the marks for all questions were added to get a net or grand total mark.

This Method had Several Advantages and Disadvantages.

The advantages were that the studious were clear demarcated from the not so studious types of students but this led to intense pressure in-between the students and learning was not revered to be fun but rather a hard task which they had to deal with. 
This led to the advent of the grading system. Let us see the advantages and disadvantages of grading system.
The advantages of the grading system are many one being the pressure on the students to study has significantly reduced. 
This is because of two things; one is that the students are being grouped together into certain grades based on their marks. 
A common grading scale in the United States is A- 90 to 100, B- 80 to 89, C- 70 to 79, D- 60 to 69, E- 0 to 59.
In case of India the general pattern is as follows A1: 91 to 100, A2 : 81 to 90, B1: 71 to 80, B2: 61 to 70,  C1 : 51 to 60, C2 : 41 to 50, D for 33 to 40 and lesser for E's. 
Another advantage that this method has brought in is that it has introduced the concept of assessing the students based on their assignments and overall performance and not just a single test driven method. 
Earlier the marks obtained in the exams were the only indicator of whether a student is performing well or not. 
But with their assessments also being considered for their final assesment the pressure towards having to score extremely well in the final exams has reduced. 

But these advantages have also turned to be the disadvantages of the grading system. 
The fact that a student scoring 100 out of 100 without any mistakes and a student who scored 90 out of 100 with several mistakes to be grouped together actually de-motivates the student studying well. 
Also the spirit of competition has reduced as the student studying moderately would not try that hard to understand everything as he knows very well that he has a scope to make a few mistakes and still get a decent grades. 
Also the fact that assignments will be considered for the overall marks makes the students lethargic towards studying well for the exams as they know how much to get in the exams to pass.
Moreover, the onus now lies on the subject teacher and their honest assessment of a particular student for overall grading rather than the true merit of that student. 
Ultimately the students will study to pass and not to learn, which was the same problem in the case of the marking system. 

The disadvantages of grading system include the fact that students cannot be differentiated with respect to one another as more than two students with different capabilities in terms of their intellectual capabilities will fall into the same group. 
Thus a teacher will not be able to know which person needs more special attention than the other. 

Even though there are several disadvantages of grading system it has removed several disadvantages of the marking system. 
A recent survey has shown that with the advent of the grading system the number of students among students with respect to examination has drastically reduced. 
So the grading system has to be looked upon for improvement and not replaced with any other system.
