Who We Are


Our mission is to be the platform for facilitating linguistic growth and awareness for all language learners, in the US and abroad. Educators adopt Extempore to enhance practice and maintain assessment security, while students grow more confident and feel at ease when speaking. As a result, users on both ends are equipped for success.
Our teachers and their invaluable insight are the pillars of our success. Through developing close relationships with our users, we continuously enhance their experience and, most importantly, together we help students reach their proficiency goals.
