Answer: Item difficultly is near 50
Explanation
In norm-referenced tests, the best item is one whose difficulty is near 50.
This means that the item has an equal chance of being answered correctly or incorrectly by the test takers, making it a good discriminator between high and low performers.
Items with extreme difficulty levels (near zero or near 100) may not effectively differentiate between students' abilities.
