Classroom Assessment Techniques are not meant to take place of more traditional forms of classroom evaluation. Rather, these formative assessment tools are meant to give teachers and students information on learning before and between tests and examination; therefore, they supplement and complement formal evaluations of learning. Used effectively, (CATs) can reduce the uncertainty that faculty and students feel as they face midterms, final examinations, and the calculation of course grades. When teachers and learners both receive regular feedback on student learning throughout the course, there are likely to be fewer surprises at semester’s end.
