In any assessment, but especially high stakes certification exams, it is extremely important that we are fair to all test takers. Fairness is often considered in relation to individuals who have special educational needs but is actually much broader. A test may be unfair because the level of English is far beyond that of the test taker when it doesn’t need to be. It could be unfair because it requires knowledge of a specific geographic location or activity (think questions about sports data). All of these can cause what we call … . We want to avoid this as much as possible, so keep in mind the follow as you write.
Our test takers come from an international audience. We use US English when writing our items but also think about the language level. We are not testing English language ability. Keep sentences short, in the active voice, and use simple vocabulary. There are a range of useful online tools that can help you out. Take a look at Hemmingway App to get you started.
Topics to Avoid
Some topics may introduce bias by causing distress or offence to test takers. This includes (but is not limited to):
Race or religion
Gender related topics
Smoking, gambling, drug use
Gender in Items
Commonly in teaching materials we are told to ensure that we balance the use of gender. For DataCamp assessments we recommend that you avoid the use of gender in the context of items entirely. Why? Our tests are adaptive. This means that we have no control over which combination of items our test takers see. We can have carefully crafted a balanced set of items only for the test taker to see a subset that appears to be imbalanced.
When it comes to gender in data, if you do feel it needs to be used, ensure that you provide a balance and do not conform to gender stereotypes e.g. all female names have stereotypically female roles.
It often seems that sporting data fills data related training courses, probably because it is often freely avaiable. While it may be ok to use in teaching materials we ask that you do not use it in test items. This may seem like a very harsh policy but sport can have regional differences that lead to bias. A simple example, Football in most of the world is not the same as Football in the US. I may lose lots of time on an item being distracted by not having understood this difference, but it wouldn’t tell me anything about my data skills.
This can be one of the hardest to ensure we stick to, but make sure that you are not testing general knowledge or giving an unfair advantage to individuals with specific knowledge. One of the most common examples of this is Geography. It is common to use US centred data and assume a general knowledge of US geography. Avoid this as much as possible. And remember, our audience is international, so try to avoid repeated use of US, Cananda, UK etc.
