The majority of our teachers are long-time residents of the community, both Costa Rican and North American. Other teachers come to us from the United States or Canada.  We highly value and respect our team members and work hard to create a positive working environment, resulting in a high rate of long-term teacher retention and a stable learning environment in the school.  We also have a strong volunteer program. We generally post any job openings in January-April, but we also encourage you to follow us on Facebook and sign up for our bi-monthly newsletter to learn of other opportunities.
