  • 1. Item characteristic function: probability of a correct response to an item as a function of ability
  • 2. test characteristic function: sum of item characteristic functions, can be used to predict scores of examinees at given ability levels
  • 3. item information function: shows the contribution of items to the assessment of ability (items with high discriminating power contribute more to measurement precision than lower discrimination item)
  • 4. test information function: sum of item information functions, estimates of errors associated with ability estimation
