This document discusses assessment of children with special needs. It defines assessment as the process of collecting educational data to make decisions about students or schools. Assessment aims to help teachers understand each student's level and determine next steps to improve learning. Testing is a form of assessment using specific problems to evaluate students' knowledge, intelligence or abilities. The main legal bases for assessment of individuals with disabilities are the Individuals with Disabilities Education Act (IDEA), which ensures publicly funded special education, and the No Child Left Behind Act (NCLB), which requires stronger accountability and testing standards.
