Assessment tools are instruments used to evaluate, measure, and analyze a person's knowledge, skills, or performance. These tools can take various forms, including tests, quizzes, surveys, and observational checklists. They help educators, employers, and researchers gather objective data to make informed decisions about learning progress, job performance, or research outcomes. Common examples of assessment tools include standardized tests like the SAT or ACT, which measure academic readiness, and performance assessments that evaluate practical skills in real-world scenarios. These tools are essential in educational settings, workplaces, and clinical environments to ensure accurate assessments and improve outcomes.
