Writing Test Questions Well – Part 1 of 3
Very often an organization wants to prove the effectiveness of its training by administering some kind of test at the end of the training. Unfortunately, most trainers are not skilled in writing test questions. It is much more than simply writing 20 questions about the content. You can skew the results of the test (and consequently get inaccurate feedback about the effectiveness of the training) if your test questions are not designed correctly.
In this first of three articles on designing appropriate test questions, we will discuss multiple choice questions and how best to design them.
Typically, when someone is not skilled at writing multiple choice questions, the correct response will always be the longest one – try to be aware of this and keep your answers to the same length.
It’s MUCH easier to provide 3 alternatives than 4. Don’t make it hard on yourself. Your responses should include one right answer and there incorrect but plausible ones.
One of the ways to ensure you have plausible, but incorrect, answers is to ensure that each of your choices is logically consistent.
Check off all answers that are dominant colors:
Your plausible but incorrect answers don’t have to be terribly difficult – keep in mind that you are testing people who have new knowledge and limited skill/experience – don’t come up with answers that would stump you, come up with answers that would stump the unskilled person. By the same token, the right answer shouldn’t jump out from the list.
If your answer begins with a vowel, the preceding question should end with “a(n)”; if it ends with an – which is grammatically correct – the question itself automatically triggers the trainee to choose the answer that begins with the vowel.
Example: Example: The Interstate is also known as an:
Do you see / hear how ending the question with an forces you to choose Expressway?
All choices should begin with similar phrasing or sentence structure.
The time to cross the street is:
A. When the light turns green
B. After you have looked both ways
C. If the road is clear
The best time for fly fishing is:
C. April to May; after the ice pack has melted
Beware of All of the Above. If you’re going to provide “all of the above” (or “none of the above”) as one of your choices, you should include it in ALL of the choices. If you have 15 multiple choice questions and only 1 or 2 have the option of “none of the above,” it’s a clear signal that the right answer is none of the above.
These guidelines for developing well written multiple choice test questions should help to ensure that you are able to precisely gauge your trainee’s level of learning.
