You can add multiple evaluation criteria for any evaluation round in your program. This is done from Evaluation > Rounds, by using the Score voting option when setting up your round.
Use the Add criteria button to add as many criteria as you want for this round of the evaluation phase.
When judges evaluate a submission, the system calculates all different criteria and each criteria's weight to form the total score of the submission for this round, according to the Total score scale set for this round.
Criteria weights explained
With the Score voting type of voting, you can set multiple criteria for judges to evaluate shortlisted submissions. Setting the weight of a criteria means you to set how much it contributes to the total score of a submission for the voting round.
The best way to understand how these weights work is by thinking of them as a percentage distribution towards the total score and making sure the sum of the weights across all criteria is 100.
Some quick examples
Example A: You have 2 criteria that judges will use to evaluate submissions for your program. If both criteria have equal importance, you can set a weight of 50 for each, meaning each would contribute 50% of the total score of the submissions.
Example B: You have 3 criteria that judges will use to score program submissions. The weights of the 3 criteria can be set to 60, 20, and 20, where 60 is the weight of the key criteria, and 20 is the weight of the other 2 less important criteria.
