Orchestra (beta)

Orchestra is a web app that helps schools to find the perfect teacher. It’s designed to reduce discrimination during the hiring process. Orchestra was inspired by a 2000 Harvard study on gender discrimination in symphony orchestras. The study found that if orchestra auditions were “blind”, there was a significant increase in the likelihood of female musicians being hired. Learn more about the research here.
