  • 9. Assessing Language and Communication Chapter 10
  • 10. Understanding Assessment
    • Assessment
      • Process of collecting data for the purpose of making decisions about students
    • Testing
      • Administering a particular set of questions to an individual or group of individuals to obtain a score

      • Screening
      • Eligibility
      • IEP planning
      • Monitoring progress

    • Types of assessment procedures
      • Formal
        • Standardized: norm-referenced or criterion-referenced
      • Informal
        • Assess current levels of functioning
  • 12. Assessment of Language

      • Nouns, verbs, adjectives and word order
