This document discusses assessment in education. It defines assessment as a process used to collect information to improve educational programs and student outcomes. There are three main types of assessment: formative assessment which occurs continuously to guide instruction, summative assessment which evaluates learning at the end of a unit, and authentic assessment which applies knowledge over time with clear criteria. The purposes and roles of assessment are to identify gaps in student learning and inform classroom teaching. Different strategies are used for each assessment type, such as quizzes and questioning for formative and exams or projects for summative. The goal of assessment is to continually improve academic progress.
