"What I liked is the attention that the entire staff demonstrates with regard to all aspects of the study abroad experience. The classes, housing and tour arrangements could not be any better. Since I take students from the United States to Costa Rica every year, I had to find a well established institute with reliable personnel. After interviewing directors from various schools as well as visiting their premises, I had no difficulty choosing this schools. Their staff will do everything possible to help the student master the Spanish language in a very friendly environment. They are also there to help in any situation that may arise. My students and I are thoroughly satisfied."

“We are very glad that we chose COSI. The entire staff is professional and organized. Our teachers at COSI were excellent! The COSI school in Manuel Antonio is a facility with an amazing view of the Pacific, and the fresh fruits and coffee at break times are always delicious. Our 4 weeks at COSI was a most worthwhile vacation. ¡Perfecto!”

Vanessa Chester, New Zealand

“During my 8 weeks studying, I found the teachers to be dedicated and very capable. As the class sizes are kept small, I was able to focus on what I needed to learn and I greatly increased my speaking ability. I met students from all over the world and enjoyed the culture of Costa Rica. I highly recommend this school to anyone.”

Simona Giselbrecht, Switzerland

“I really had a great time in Costa Rica!! The experience I made is unforgettable, everybody at the schools and in the host family are very friendly, helpful and open-minded. I highly recommend!!”

Dirk Wasser, The Netherlands

“I went to Costa Rica without any knowledge of Spanish. However, I felt at home and soon I was able to communicate with Costa Ricans.
I have not only learned Spanish now, but also I have made a lot of friends with both the other students as well as the teachers. If you attend here, I am sure you will have the time of your life!”

Karen Dockery, USA

“When I arrived in Costa Rica, I was somewhat anxious because I did not know anyone and my Spanish was basic. By the time I left (2 months later), I was close to fluent in Spanish and had met many new friends from several different countries. I also felt welcomed into the "family" of the school which includes it's teachers, staff, students, etc. All of the connections I made in Costa Rica have had a lasting impact even to this day.”
