Since 1972, people from all over the world have learned to communicate effectively and with confidence in English at Converse International School of Languages (CISL). CISL has two adult schools, one in San Francisco and one in San Diego, and both schools offer a variety of language courses to help students improve their skills in English. CISL also has several junior programs throughout the year across the U.S. for students ages 13‐17. 

One of the things that makes CISL special is its focus on small class sizes. Every CISL class has a maximum of 8 students, and the Global Success (San Francisco) and Executive English (San Diego) courses have a maximum of only four students per class! Learning and using a second language can be stressful and challenging. Being in small classes helps CISL students to feel comfortable, to get personal attention from their teachers, and to focus on their particular needs and goals. 

Since people have many different reasons for learning English, CISL offers a variety of English courses in academic English, business English, and more. People also have different schedules and amounts of time available, so many of CISL’s courses allow students to join a class on any Monday and stay for any number of weeks. Students can customize their schedules and enroll in the courses that will help them achieve their goals in the time that they have available.
