💰 Judging Criteria

ℹ️ Covalent judges submissions based on their technical merits as well as the creativity and implementation details.

In general, submissions are graded on a 1-5 scale in each of the following categories

Originality: Does the template incorporate something entirely novel, or at least take a fresh approach to an existing problem?
Execution: Is it usable in its current state? Is the user experience smooth? Does everything appear to work? Is it well-designed?
Usefulness: Is the idea practical? Is it something people would actually use?
Learning: Did the individual or team stretch themselves and push the boundaries of learning in this space?
