The panel of judges evaluated Stage 1 submissions using the following selection criteria. These criteria were used to select up to eight (8) Stage 1 finalists.  

Accuracy. The degree to which the solution would be able to detect, recognize, or indicate the presence of opioids in a parcel consistently and with a high degree of confidence. This includes the degree to which the solution addresses and minimizes both false positives and false negatives.

Speed. The potential for the solution to rapidly inspect parcels, considered in terms of potential inspections per unit of time.

Feasibility. The extent to which the proposed solution uses technically sound methods backed by credible supporting evidence and can be developed into a testable prototype within a four-month period.

Usability. The ease with which operators could learn, use and maintain the solution.

Flexibility. The extent to which the solution could adapt to a changing threat, including shifts in trafficker behavior, changes to opioid chemical composition patterns and detection of other threats such as new drugs or explosives.

Team. The extent to which the entrant or entrant team demonstrates the strong experience, commitment and ability needed to develop the solution from plan to testable prototype within the time and resource constraints of the Challenge.  

Stage 1 was open to international and domestic participants, as defined in the Rules, Terms and Conditions.
