“Speak English” signs found in secondary schools in Ukerewe, an island on Lake Victoria, and Mwanza, in northwestern Tanzania. Many secondary schools strictly enforce the use of English — a new language for most secondary school students, as Kiswahili is the medium of instruction in primary schools. Many students are not given adequate support to transition from Kiswahili to English, and some reported being punished for not speaking English in class. In 2014, the government adopted a policy to allow the dual use of Swahili and English as languages of instruction in secondary schools.
