2020 Call for Code Global Challenge Timeline


Submissions will be judged equally across 4 primary criteria which evaluate whether the solution solves a real-world problem and uses technology effectively.

Completeness and transferability

How fully has the idea been implemented? Can it achieve an impact in the field? Can it be transferred elsewhere?

Effectiveness and efficiency

Does the solution address a high priority area? Does it achieve its goal effectively and efficiently? Can it scale?

Design and usability

How good is the design, user experience, and ease of use of the solution? How quickly can it be put to use?

Creativity and innovation

How unique was the approach to solving a long-standing or previously intractable problem?
