Assignment Evaluation Criteria Calculation
Note: This feature is accessible only to users for whom it has been enabled.
When evaluating a learner's performance in an Assignment Pro, multiple criteria are rated. Each criterion includes:
- Minimum Rating
- Maximum Rating
- Weight or Total Score
- Learner's Rating
Rating Range Calculation
The Rating Range defines the number of rating levels between the minimum and maximum rating values, including both endpoints.
Formula
Rating Range = (Maximum Rating + 1) - Minimum Rating
Adding +1 ensures that all rating levels are included in the calculation.
For example, when the minimum rating is 1 and the maximum rating is 10, the rating range is 10, representing all ratings from 1 to 10.
Example
If a criterion has:
- Minimum Rating = 1
- Maximum Rating = 10
Then:
Rating Range = (10 + 1) - 1 = 10
Therefore, the rating range is 10.
Criteria-wise Score Calculation
The Criteria-wise Score calculates the score earned by the learner for an individual criterion based on their rating and the total score assigned to that criterion.
Formula
Criteria-wise Score = (Gained Rating / Rating Range) × Total Score
Where:
- Gained Rating = Learner's rating for the criterion
- Rating Range =
(Maximum Rating + 1) - Minimum Rating - Total Score = Weight or maximum points assigned to the criterion
Example
Consider Criterion 1 with the following values:
- Minimum Rating = 1
- Maximum Rating = 10
- Learner's Rating = 8
- Total Score (Weight) = 5
Step 1: Calculate the Rating Range
Rating Range = (10 + 1) - 1 = 10
Step 2: Calculate the Criteria-wise Score
Criteria-wise Score = (8 / 10) × 5 = 4
Therefore, the learner earns a Criteria-wise Score of 4 out of 5.
Overall Score Calculation
The Overall Score represents the learner's total performance across all criteria, expressed as a percentage.
Formula
Overall Score = (Sum of Learner's Criteria-wise Scores / Sum of Total Scores) × 100
Where:
- Learner's Criteria-wise Scores = Actual scores earned for each criterion
- Total Scores = Maximum possible scores for all criteria combined
Example
Consider the following two criteria:
| Criterion | Total Score | Learner's Rating | Rating Range | Criteria-wise Score |
|---|---|---|---|---|
| 1 | 5 | 8 | 10 | (8 / 10) × 5 = 4 |
| 2 | 8 | 8 | 10 | (8 / 10) × 8 = 6.4 |
Step 1: Calculate the Sum of Learner's Scores
4 + 6.4 = 10.4
Step 2: Calculate the Sum of Total Possible Scores
5 + 8 = 13
Step 3: Calculate the Overall Score
Overall Score = (10.4 / 13) × 100 = 80%
Therefore, the Overall Score is 80%.
