Assessment is the systematic gathering and analysis of information about student learning or program effectiveness. It is used to improve student learning outcomes and inform instruction. Assessment includes tests, but also broader methods of evaluating student progress, skills, knowledge and motivation. The key purposes of assessment are to improve student learning, inform teaching, and evaluate program results against objectives. Assessment can be formative, summative, or for diagnostic purposes. Authentic assessment evaluates students' ability to apply skills in real-world contexts through tasks and projects.
