Why join CAST?
Your CAST membership includes:
Professional Development Opportunities and Networking. As a member, you'll learn about professional development opportunities through our website and social media (Facebook and Twitter.)

Rural CAST members may apply for scholarships up to $100 to attend the Colorado Science Convention.

CAST Awards. CAST members have the opportunity to be recognized and to nominate Colorado teachers for excellence in science education.
Friends of CAST Benefits. CAST has developed partnerships with the following organizations that give free or reduced membership, free admission and/or discounted educational programs to show support for CAST members.
