The application for the 2026 TASS programs will be due December 3, 2025. See the TASS Timeline for details.

TASS 2026 will be held from June 21, 2026 – July 25, 2026.

TASS applications are open to high school sophomores and juniors (“rising juniors” and “rising seniors”). Participants must be at least age 15 at the start of the program and no older than 17 by the end of the program. Both US and international students are welcome to apply. We admit applicants from all backgrounds, and welcome applications from Black and Indigenous students, other students of color, and/or students who have experienced economic hardship. We seek students who are intellectually curious, community-minded, and self-motivated.

For students currently in high school or homeschool in the US, birthdates must be between July 26 2008 and June 21 2011.

For students studying outside the US who do not have a US passport, birthdates must be between July 26 2009 and June 21 2011. International students (those studying outside the US who do not have a US passport) must be sophomores to apply.

If you are submitting your application online, please be aware that you will need to copy and paste your essays into text boxes. Please insert an extra blank line between paragraphs and be aware that any special characters or formatting will not be preserved. We recommend that you write and proofread your essays in a word processor before you submit your application. Please make sure to save your application between pages and between sessions.

In a given year, you may only apply to one of these two programs (TASS-CBS or TASS-AOS). If you attend one program in your sophomore year, you may not apply to that same program the following year, but you are still eligible for the other. For example, you could participate in TASS-AOS your sophomore year, and then apply to TASS-CBS your junior year if you wanted. We encourage applicants to think seriously about the differences between the two programs and apply only if genuinely interested in that program’s focus.

Telluride is committed to fostering a safe environment and following COVID-19 health and safety protocols in accordance with guidance from the CDC and our host institutions. In summer 2023, we required all participants to be up-to-date on their COVID vaccinations and conducted regular COVID testing during the programs. Exceptions are available for medical and religious accommodations. Due to the evolving nature of this pandemic, it is not possible for us to fully predict what measures will need to be in place in summer 2026. We are continuing to monitor the situation and will announce requirements and protocols closer to the program’s start.
