Structure
The structure has three key elements:
- Answer option list
- Sources suggest using a minimum of eight answer options to a ratio of five scenarios or vignettes to ensure that the probability of getting the correct answer by chance remains reasonably low.. The exact number of answer options should be dictated by the logical number of realistic options. This ensures that the test item has authenticity and validity.
- Lead in question
- This should be as specific as possible and on reading the lead in question it should be understand exactly what the student needs to do - without needing to look at the answer options. If you need to look at the answers to understand the question, the item has not been well written.
- Two or more scenarios or vignettes
- There should be at least two vignettes, otherwise this becomes an MCQ. Because the item allows for an in depth test of knowledge each of the scenarios should be related to one another by a theme that summarises the question overall. Each scenario should be roughly similar in structure and content, and each has one 'best' answer from amongst the series of answer options given.

Famous quotes containing the word structure:
“... the structure of our public morality crashed to earth. Above its grave a tombstone read, “Be tolerant—even of evil.” Logically the next step would be to say to our commonwealth’s criminals, “I disagree that it’s all right to rob and murder, but naturally I respect your opinion.” Tolerance is only complacence when it makes no distinction between right and wrong.”
—Sarah Patton Boyle, U.S. civil rights activist and author. The Desegregated Heart, part 2, ch. 2 (1962)
“Just as a new scientific discovery manifests something that was already latent in the order of nature, and at the same time is logically related to the total structure of the existing science, so the new poem manifests something that was already latent in the order of words.”
—Northrop Frye (b. 1912)
“Man is more disposed to domination than freedom; and a structure of dominion not only gladdens the eye of the master who rears and protects it, but even its servants are uplifted by the thought that they are members of a whole, which rises high above the life and strength of single generations.”
—Karl Wilhelm Von Humboldt (1767–1835)
