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.
