An important aspect of Bihar D.El.Ed exam that every candidate should be aware of is the normalization process. Bihar D.El.Ed normalization process plays an important role in ensuring fairness and accuracy in evaluating the performance of the candidates in different examination shifts. In this article, we will take an in-depth look at how this process works and why it is an integral part of the exam.
How does Bihar D.El.Ed normalization process work?
Bihar D.El.Ed exam is conducted in multiple shifts, and each shift may have question papers of different difficulty levels. To ensure fairness and eliminate any bias in scoring, a normalization process is applied. This method compares the performance of candidates from different shifts, taking into account the difficulty level of each set of questions. The scores are then adjusted to reflect a level playing field, ensuring that no candidate is unfairly influenced by the shifts they have attended. Through this process, Bihar D.El.Ed exam ensures that all candidates are evaluated on an equal basis, irrespective of the time or place of examination. In which shift they give the exam.
Step by Step Bihar D.El.Ed Normalization Process
The normalization process is important to ensure that all candidates are assessed fairly, especially when there is variation in difficulty levels across exam shifts. Since examinations are often conducted in multiple shifts, one shift may have easier questions than the other, giving candidates an unfair advantage or disadvantage. To address this, the normalization process adjusts the raw scores of the candidates, ensuring that differences in difficulty do not affect the fairness of the results. Here’s how the calculations work:
- Raw score collection: Initially, raw marks are collected for each shift, which is the number of correct answers provided by the candidate.
- Difficulty Index: The exam difficulty of each shift is assessed on the basis of how well the candidates have performed in that shift. For example, if candidates from one shift perform significantly better than candidates from the second shift, it suggests that the first shift was easier.
- Formula Application: A formula is applied to adjust the raw scores. The formula looks like this:
-
- Average score of that shift: It is the average score of all the candidates in that particular shift.
- Variation in scores for that shift: This shows how much the marks of that shift differ from the average marks. If most of the candidates have scored similar marks, the variation is less. The variation will be greater if the scores are spread out.
- Overall Average Score: This is the average score of all the candidates in all the shifts.
- Overall variation in scores: This shows how much the overall score varies across shifts.
- Adjusted Score: The formula adjusts the original score of each candidate by considering the difficulty of the shift for which they appeared. The result is an adjusted score that provides a fair comparison between candidates from different shifts.
- Final result: The final adjusted marks are used to rank the candidates and determine their eligibility for selection, thereby ensuring fairness in all shifts.
