This study investigated the perceptions, preparedness of, and the challenges encountered by teachers of English as they implemented the CSEC English SBA in Jamaican secondary schools for the first time. Data collected through a survey of 124 randomly selected teachers of English and analyzed using descriptive statistics, t-Tests, ANOVA, and crosstabulations showed that teachers had a predominantly negative perception of the CSEC English SBA. This negative perception was strongly and positively associated with the teachers’ being unprepared to implement the English SBA.
