Most of the guidance assumes that the computer delivered assessment is to be used by candidates who are not experts in computer use.
Special considerations apply where candidates are being assessed in computer-related skills.
The presentation, appearance and functionality of the software should be consistent within the test or application, for example in the way multiple-choice questions are presented the method by which the candidate answers the method of moving forwards or backwards or quitting. If a second question relates to the same stimulus material, then the stimulus material should ideally remain on the screen while the second question is being displayed alternatively, the candidate should be able to move easily between question screens and stimulus material or to scroll through stimulus material large diagrams could be provided in printed form, in which case candidates should be advised to refer to the invigilator or assessor if they do not have them. Results should be monitored to ensure that different combinations of questions are in fact equivalent in difficulty. There should also be user trials to check that the software is easy to use by a variety of users. In assessment of keyboarding and similar skills it is important to test that a candidate who omits one or more characters or inserts an additional character is given credit for subsequent correct work.
