Teaching and assessment are highly interwoven. The assessment methods used in classrooms influence the teaching learning process either positively or negatively. Continuous assessment makes assessment more meaningful and more representative of the learners overall abilities. Since it involves data gathering over a long period of time, it yields more accurate data reaching the teachers early enough to modify instruction. It also captures the full range of learners' performance. It employs a variety of assessments; uses of a formative approach; emphasizes progress toward specific levels of mastery and provides constructive feedback to students. However, some challenges can exist in implementing continuous assessment. This book, thus, attempts to explore opportunities and challenges in using continuous assessment in English as Foreign Language classes at tertiary level.
