國語 / 普通話會話課程從四年級開始加入，先從漢語拼音開始，然後引入日常對話。四年級的學生已建立了一定的中文基礎，能幫助學習國語發音事半功倍，也避免了幼童學生區別英語及漢語拼音之間的困難，使粵語學生更易於掌握國語會話的應用。
The Cantonese Program is designed for students who speak Cantonese at home. By building on what children already use at home, we raise their interest in learning Chinese through nursery songs, games, and stories. What they learn in Berryessa Chinese School can be practiced at home with the parents, grandparents, and other relatives. Not only will the children find learning Chinese useful, but they will also find it an achievement and an encouragement. It helps to establish a foundation for a lifelong learning experience.
The Cantonese Program curriculum also includes the teaching of Mandarin conversation lessons, starting from 4th grade. We start with Mandarin Hanyu Pinyin pronunciation, and then introduce situational daily conversation so that our Cantonese students can develop their verbal skills in Mandarin.
