This document provides an overview of standardized assessments, including their purpose, types, administration, scoring, and accommodations. It defines key terms like norm-referenced vs. criterion-referenced tests and explains how to evaluate reliability and validity. Scoring methods like raw scores, standard scores, percentiles, and grade equivalents are outlined. The concept of a normal distribution curve is introduced to show how scores are distributed. Accommodations for students are described to ensure abilities are assessed rather than disabilities.
