CAST21 Terms & Conditions

Payment Options

All attendees must register online and pay directly via credit card or by providing a school district purchase order (PO) and payment by check.

If using a PO number to complete online registration, please mail all checks to:

Science Teachers Association of Texas or STAT
3305 Steck Avenue, Suite 200
Austin, TX 78757

Full names of all attendees or their confirmation numbers must be included with the check.

Cancellation and Refund Policy


Cancellation/Refund Deadline: October 29, 2021. After this date, registration fees are typically nonrefundable. Attendee cancellation and refund requests must be in writing and received by email at stat@statweb.org or postmarked by October 29, 2021, and mailed to: Science Teachers Association of Texas or STAT, 3305 Steck Avenue, Suite 200, Austin, TX 78757. A $25 fee will also be charged for insufficient fund checks and disputing valid credit card charges.

Registrants who do not pay their balance may not be eligible to attend future CAST conferences. Please know that your registration is a “reservation” to attend CAST21; therefore, unless you cancel by the deadline, you are responsible for full payment of your registration, regardless of your attendance at the conference. 

Cancellation Considerations Due to COVID-19:

  • Providing a safe environment for all CAST attendees remains STAT's top priority as we continue to navigate the ongoing pandemic. Visit the COVID Safety page to review the CAST21 COVID-19 safety policies.
  • If attendees do not wish to follow the published policies or have concerns related to COVID-19, they may cancel their registration by notifying STAT directly in writing no later than October 29 at stat@statweb.org, and normal administrative cancellation fees will be waived if received before the deadline. 
  • Cancellations for refunds after this date will be considered on a case-by-case basis.

Additional Cancellation Options:

  • If registering at the nonmember rate and canceling for any reason, you may choose to apply $30 to cover STAT membership. 
  • A virtual version of CAST will be offered in February 2022 and will feature selected content from the in-person event. Attendees who need to cancel due to COVID-19 may also choose to transfer their in-person registration to the virtual event at the virtual-only rate.

Changing or Substituting a Registration

You may substitute another attendee from the same district/organization for your registration at no charge by logging in to the Attendee Service Center. There, you may change the name and update the necessary contact information. All registration transfers must be completed before October 29, 2021, as substitutions will not be allowed during the event.
