NAVY SCHOOL MANAGEMENT MANUAL

• Is there no correct answer or more than one
correct answer?
• Is the question clear to the student?
If the test item is determined to be sound, the next
step is to review the instructional material.
• Is the information correct?
• Does the material in the student guide support
the information in the lesson plan?
• Does the information in the technical manual
support the material in the lesson plan?
If the instructional material is correct, next
evaluate the classroom instruction.
• Was the material taught correctly?
• Did the student receive practice prior to
testing?
• Was there adequate time allowed for review and
summary of the material?
• How effective was the instructor in the delivery?
• Can the poor performance of the test item be
tracked to a specific instructor?
Once all the information has been reviewed, several
possible actions may occur.
• The test, instructional materials, and/or master
schedule may require a change.
• Some areas may be corrected through instructor IS
training. This can be technical or technique in
nature.
• The final possible action is to make no change
until further data is collected.
Techniques for Test Item Analysis. Item Difficulty calculates
the difficulty of the test item. If the item does not have the
correct degree of difficulty, then it may not effectively
discriminate. The acceptable range of difficulty for technical
training is .50 to .90.
To calculate the difficulty index, take the complete sample
and use the following guidelines:
Count the total number of correct answers and divide
by the total number taking the test.
