This article presents reflections and guidance concerning assessment literacy in teacher education. Previous inadequacies in teacher training in educational assessment highlight the need for teachers to be assessment literate. Assessment literacy consists of an individual's understanding of the fundamental assessment concepts and procedures deemed likely to influence educational decisions. Due to the current focus on accountability assessments, it is in teachers' best interest, and also the students', that teachers develop a level of understanding in assessment. Assessment, when used appropriately, is also a powerful tool for learning. What is needed to facilitate assessment literacy in teacher education is more than a brief mention of assessment in a course. A course in assessment with an appropriate text is necessary to bring a more complete understanding of assessment to beginning teachers.
