Lesson 14:Interpretation of assessment information

Ensuring the authensity and trust worthiness of data

Before interpreting the information one should check for
  • Enough samples
  • Representativeness of the sample in respect of what is being assessed.
  • Whether samples are balanced, employing different sources, methods and contexts.
  • Evidence obtained in different ways converges
  • Consistency of information over time, sources, contexts and methods.

Additional safeguards to maintain quality and trust worthiness are

  • To determine progress, compare performance at two or more points in time
  • Work from compilations and summaries:
    • Use information collected from many sources
    • Use recorded information
    • Do not relay on memory alone.
  • Look for patterns, including patterns of errors rather than isolated instances.
  • Considering child’s or group’s unique and individual patterns of development, temperament, interests and dispositions.
  • Identifying areas of concern: always consider the concerns of the child, parents and teachers by looking in-depth at the developmental area of concern.
