Normalization Process for DSSSB TGT/PGT/PRT Exam Result Calculation:

Introduction:
The DSSSB (Delhi Subordinate Services Selection Board) conducts recruitment exams for various teaching positions such as TGT (Trained Graduate Teacher), PGT (Post Graduate Teacher), and PRT (Primary Teacher). To ensure fair evaluation and selection of candidates, the DSSSB follows a normalization process for calculating the exam results.

Normalization Process:
The normalization process used by DSSSB for calculating the TGT/PGT/PRT exam results involves the following steps:

Step 1: Conversion of Raw Scores to Standard Scores:
- The raw scores obtained by candidates in different subjects are converted into standard scores using a statistical formula.
- This conversion helps to eliminate variations in difficulty levels across different subjects and ensures a fair comparison between candidates.

Step 2: Calculation of Mean and Standard Deviation:
- The mean and standard deviation are calculated separately for each subject.
- The mean represents the average performance of all candidates in a particular subject, while the standard deviation indicates the spread of scores around the mean.

Step 3: Calculation of Z-Score:
- The z-score is calculated for each candidate's standard score in a subject.
- The z-score represents the number of standard deviations a candidate's score is above or below the mean.
- A positive z-score indicates a score above the mean, while a negative z-score indicates a score below the mean.

Step 4: Normalization of Z-Scores:
- The z-scores obtained by candidates in different subjects are normalized to bring them on a common scale.
- This normalization ensures that the performance of candidates in different subjects can be compared directly.

Step 5: Calculation of Weighted Score:
- The normalized z-scores are multiplied by the weightage assigned to each subject.
- The weightage represents the importance or contribution of each subject in the overall evaluation.
- The weighted scores for each subject are then added together to obtain the final score for a candidate.

Step 6: Ranking of Candidates:
- Based on their final scores, candidates are ranked in descending order.
- The highest-scoring candidate is ranked first, and the rankings continue accordingly.

Conclusion:
The normalization process used by DSSSB for calculating the TGT/PGT/PRT exam results ensures fairness and eliminates any variations in difficulty levels across different subjects. By converting raw scores to standard scores, calculating z-scores, normalizing them, and assigning weightages, the DSSSB ensures a standardized evaluation process for all candidates. This process allows for a fair comparison of candidates' performance and helps in the selection of the most deserving candidates for teaching positions.
