Study Notes

Item Facility

  • Calculate the difficulty level by dividing the number of correct responses by the number of students assessed.
  • The difficulty index ranges from 0.00 (no one answered correctly) to 1.00 (everyone answered correctly).
  • The larger the difficulty index, the easier the item.
  • The acceptable range of difficulty for technical training is 0.50 to 0.90.

    • Is there a pattern of correct answers throughout the test?
    • Which items, if any, were missed by all or almost all of the students?
    • Which items, if any, were omitted by a high percentage of students?
    • And so on...
  • Answers to these questions serve as the starting point for the analysis and revision of tests and their items.

Learn about the Item Facility and how to calculate the difficulty level of a test item, ranging from 0.00 to 1.00, based on the number of correct responses and total students assessed.
