Closing Ceremony Speaker

Do you have a STEM story to share with an early elementary audience (grades K-4) that inspires an openness and curiosity to possibilities? A story that instills confidence in their ability to learn and do things; letting them know that they are capable of affecting positive change in their own lives, their communities and in the world?

Then we invite you to share your knowledge and imagine a world being different because of you!

Let us know. Send an Email to FLLJr@Stlfirst.org with a little about yourself and your topic and we will place you in an expo.


What is the initial volunteer registration process?

All volunteers need to create an account with FIRST to access the Volunteer Registration system. Click here to setup a FIRST account.

If you already have a FIRST account, log in from the home page of the firstinspires.org website on the top righthand side.

Volunteer Registration User Guide can be found by clicking here.

Once you have activated your FIRST account, you will be able to complete the “About You” and “Expertise” sections . The information in these sections will help us match you to volunteering roles that fit your interests. This information will also be helpful by providing us with dietary restrictions for catering, proper shirts size, and any physical limitations that may prohibit you from participating in certain volunteering roles. 

Why is there a background check for volunteers?

FIRST is serious about student safety. We strive to create an environment in which team members can grow, learn, and have fun with minimal risk of injury.

To ensure we are creating a safe environment for all FIRST team members, every adult volunteer from the United States and Canada must complete a background screening through our Volunteer Registration process.

How do I volunteer for specific events and volunteering roles?

Once you have completed the initial volunteer registration process and have passed our background screening, you will be able to apply for specific events and volunteering roles in the Volunteer Role Application section. You will be able to edit/delete your applications at any time leading up to the event and prior to being assigned by the Volunteer Coordinator of the event.
