Inter-rater reliability is most of concern for the "Extended essay" type of test item.

Here's why:

1. Extended essay questions require subjective grading. This means that different raters (people who grade the test) might have different opinions on what constitutes a good answer.

2. Fill in the blank and multiple-choice questions have clear, definitive answers. Therefore, it doesn't matter who grades them because the answer is either right or wrong.

3. Short-answer questions can sometimes require subjective grading, but they are usually more straightforward than extended essay questions.

4. Therefore, inter-rater reliability is most important for extended essay questions because these are the questions that are most likely to be graded differently by different people.
