Choral Literacies and Skills (CLaS)

Choral Literacies and Skills resources offer level-based developmental markers for singing groups of all ages and abilities. This critical and transformative resource has been created by Dr. Geoffrey Boers, University of Washington, and is available here with his permission. CLaS has been endorsed by national singing organizations in the US and Canada. Coastal Sound choirs use the comprehensive and inclusive CLaS resources as our curriculum, and as a “growth mindset” tool. 

CLaS resources are available FREE! Download what you need here, or visit: to learn more!
