Teaching English language revolves around the four language skills of speaking, listening, writing and reading. Although the Botswana General Certificate School Examination (BGCSE) syllabus covers the above four skills, the nature of the final examinations assesses reading and writing skills only. The study seeks to find out the reasons why only two skills are assessed and to analyse the implications of non-assessment of the speaking and reading skills on the students’ academic performance. Two qualitative research approaches were used. That is, the Questionnaire and Interview. These methods sought the opinions of English language teachers in four (4) Senior Secondary Schools and Botswana Examinations Council (BEC) officials respectively on the implications of non-assessment of the speaking and listening skills in the BGSCE examinations. The findings reveal that non-assessment of these two skills make teachers focus their attention on the reading and writing skills which are examined. They teach for examinations and less emphasis is placed on the oral communication which builds confidence in the learners’ proficiency of the English language. The study recommends that the four language skills should be assessed in the BGSCE final examinations and suggests effective ways of teaching and examining the speaking and listening skills
