With our decision to hold a virtual fair for 2021, OCSEF offers two options for student project display boards:

Option #1

Prepare a traditional display board that adheres to all specifications and restrictions. Upon completion, upload a digital picture of your board when registering your project online . The digital picture must capture ALL essential board components AND BE CLEARLY VISIBLE AND READABLE TO ANY VIEWER.

Option #2

Use a pre-designed digital backboard Google Slide Deck Template presentation, adhering to all criteria and formatting clearly outlined in the first two slides of the template. Once the slide deck presentation is completed, save the file as a PDF and upload it when registering your project online.  Although use of a digital backboard slide deck is an option, IT IS HIGHLY RECOMMENDED and will better assist students in structuring their interviews with judges
