A few Chinese American children managed to find ways to attend Caucasian schools. An unwritten rule was that they could enroll if the local community did not object—a situation that doubtless encouraged the ethnic Chinese students to be docile, respectful, and studious. This strategy could backfire, however, when high academic achievement inflamed white envy. In 1905, a group of white parents at Washington Grammar School in San Francisco insisted that four Chinese students, all academic superstars, were cheating by secretly exchanging answers in Chinese during tests. The students were separated during the next exam, but they still achieved the four top scores in the class. Undeterred, the white parents then complained to the Board of Education, which removed the four boys from the school altogether. (Chang 177-178)
