Assessment of learning refers to strategies designed to measure student achievement and determine if learning outcomes have been met. It provides evidence of students' proficiency to others such as parents, educators, and future institutions. Assessment of learning tasks must accurately reflect curriculum standards and allow students to demonstrate their understanding through a variety of methods such as tests, projects, presentations and portfolios. Teachers ensure the quality of assessment of learning through reliable, valid and equitable processes to produce defensible results that can be used to make important decisions about students.
