The document discusses student assessment in classrooms. It explains that assessment is an important part of any lesson plan and has a significant impact on the learning process. There are three main types of classroom assessment: diagnostic, formative, and summative. Diagnostic assessment occurs before learning, formative assessment is ongoing to identify progress, and summative assessment evaluates learning after instruction is complete. Together these assessments form the assessment cycle. The document also discusses using assessment data to provide feedback to students and guide instruction, as well as strategies for assessing students with learning disabilities.
