The problem of incorrect and biased scoring – how can it be prevented?

The examination is the most critical aspect of an individual’s educational journey that needs to be taken into account at all times. As a matter of fact, amongst the several factors that need to be kept in mind during the course of one’s educational journey, obtaining results through examination is certainly an aspect that one should account for at all times. There are people who spend hours, days, months - sometimes years - preparing to educate themselves in a particular vertical, in order to build their capacity to ace the tests and obtain stellar results in the same.

However, there’s not much that a person appearing for a test can control. The fact here is that another factor governing the test results that can make or break a person’s grades - human examiners. It is quite understandable that these human examiners are able to make the most of their analytical aptitude and grade tests fairly, but the fact here is that things are not as ideal as they seem. The various problems that plague the grading systems, but are overseen by a human examiner are listed below.

Build-up of Fatigue

The task of evaluating and grading hundreds and hundreds of test papers is not that easy - the examiners are bound to reach a point of restlessness and tiredness. This ultimately decreases their efficiency and negatively impacts their ability to evaluate correctly and provide accurate scores.

Human Error

Nobody is perfect! Human examiners are bound to make some errors at some point during the course of the tasks they are performing. Evaluating and grading tests is no exception to this golden rule, thereby leaving room for the probability - however minor - of an examiner marking an answer wrongfully.


Every individual is different and so are their opinions! In this light, if an examiner’s opinion clashes with the pre-set notions of what serves as a correct answer in an examination, it certainly is a problem. There is a chance that a candidate might have answered correctly, however, is marked incorrectly owing to the bias that is present in the examiner’s mind due to his difference of opinion.

The question here is - what can be done to combat this problem of incorrect and biased scoring?

Well, one of the best ways to prevent such errors in the scoring process is to completely remove the concept of human examiners. It would be more feasible to utilise the latest technological innovations and implement them in the testing system to ensure that little to no problems - like the ones mentioned above - hamper the testing and grading process.

A great example of how the use of the latest technology has augmented the current system of scoring is the Pearson Test of English (PTE). By integrating the latest technological innovations, the PTE Academic exam has completely eliminated the problems that arise in the case of human examiners. Instead, a computerised system is used to analyse and judge results. Eliminating the limitations faced by humans, these technologically-advanced systems ensure that the results are generated quickly, accurately and objectively.
