English specific to the vocabulary of finance is essential in the trading course, but a stock market professional requires an excellent level of English in other fields in order to analyze current events within commerce. The CIT requires that its students become bilingual and familiar with these fields so that they may be perfectly at ease in their residing country and in their future professional life. Students can only receive the diploma under the condition that they pass two tests: the TOEFL and the IELTS. Students can prepare for these two tests by using pedagogic material supplied by the CIT. The only linguistic course required by the CIT is English, but optional courses can be chosen by the student in order to perfect his or herself in another language under the direction of a native-speaking professor. The CIT highly recommends that students study Spanish, as it is one of the most widely spoken languages in the world, and extremely useful for daily life in Los Angeles.
