University of Innovative Distribution (UID) Year-Round When it comes to UID, the educational fun doesn't just start and stop in March. UID offers topical webinars on a year-round basis, thanks to the support of the Association Education Alliance (AEA): a consortium of 40+ distribution professional associations, in cooperation with the Department of Technology Leadership and Innovation of Purdue University. Members of NPTA receive complimentary access to these live, virtual sessions as well as on-demand recordings.
