'Assessment' and 'evaluation' are the integral parts of the engineering curriculum. These components have direct relevance to quality assurance in engineering education. Literature suggests that better assessment and evaluation practices require certain knowledge and skills about types and methods of assessment and evaluation. It is found that most of the engineering faculty members do not have concrete knowledge about 'assessment' and 'evaluation' types and methods. Further, it is argued that engineering educators are not well aware of 'feedback comments' that are associated with assessment practices. Comments on students' performances are essential because it helps them to know their strengths and weaknesses of a course. In this background, the paper critically analyses assessment and evaluation practices in engineering education setup across the globe. In particular, it discusses the challenges faced by engineering faculty members while assessing students' performances. Finally, the paper offers suggestions to improve assessment and evaluation practices so that students doing engineering programs will be largely benefited. © 2018 IEEE.
