Spark has several sets of deadlines and juries. Please carefully note the dates concerning the design category you wish to enter.
Spark is unusual in that there are different deadlines and categories throughout the year, instead of a single entry period/deadline like our friends at Core77. We do this to spread out the workload for our small (but wonderful) team and to have juries and events in both the US and Asia. We also make sure to match our student competitions to the spring semester and fall semester graduations.
Note: All dates subject to change
