Ningbo No.3 Middle School was founded in 1868. Its predecessor was Trinity College, a missionary school founded by the British. It spanned three different historical stages: the Qing Dynasty, the Republic of China and People's Republic of China (PRC), and experienced seven name changes and eight relocations. It is one of the oldest and most prestigious old schools in Ningbo. In the history of the school, there are many famous teachers. During the War of Liberation, Trinity Middle School was a private missionary school, but together with Hangzhou Senior Middle School, it was known as two democratic fortresses of China academic circles in the whole province, which produced many revolutionary fighters. The school adheres to the school-running philosophy of "development through reform, brilliance through quality, brand through characteristics and brand through scientific research", stands out in the new round of curriculum reform, and the quality of education and teaching has been steadily improved. The undergraduate rate of college entrance examination in 2009 is close to 90%. Great achievements have been made in the art education since it was founded 20 years ago. At present, it has become a leader in art teaching in the province, and nearly half of the art candidates in each class have entered the China Academy of Fine Arts. The school has also established an "innovation laboratory" to cultivate students' innovative spirit and practical ability. A large number of intelligent and innovative talents started from here. In the past five years, more than 70 people have won gold and silver prizes in national and international innovation competitions and robot contest, and won numerous awards, which has provided a practical model for the theory of quality education. The school has established sister school relations with German Friedrich-Luckert first-class liberal arts middle school and Hong Kong St. Kyle Middle School. The experimental class of German course in this school fills the gap between Ningbo's basic education and German education exchange, provides another good way for students to become talents, and becomes a demonstration window for Ningbo's international education exchange.
