Communication skills are very important in our daily job especially for those who interact with other nationalities. Thus, the auditors of Commission on Audit attended Communicare’s Communication Skills Seminar before their assignment to other other countries. The participants actively listened to the lectures about English grammar and business writing and oral communication tips. Willing to learn, they excitedly answered the writing exercises and participated in the speaking activities. Their attention did not waver until the end of the seminar.
