The passage states: "In places like Warri, Sapele and Port Harcourt, there were reports that teachers at lower primary level taught their pupils in Nigerian pidgin. This unofficial adoption of the Nigerian pidgin as the language of the lower primary education..." This clearly indicates that Nigerian pidgin is used as a language of instruction at the lower primary level in those specific areas. While the use is unofficial, it still qualifies as instructional use in an educational setting.
