Validity also covers whether the appropriate language has been used for the level the students are aiming to succeed in. An example of this could be level 4-5 wording used while testing level 3 course. This also relates to fairness which is integrated into all elements of VACSR.
Learners may be very good at a subject but assessing them with questions they do not understand would be unfair so would not be valid. Authenticity covers more than simply questioning whether it is learners own work Petty states “authentic-if you want to measure a student’s ability to design; it would not be realistic to give them a design problem to solve in half an hour. That’s not how designers work”. (Petty, 2005 p502). This statement shows there are crossovers in VACSR which is fine as long as all elements are covered. Authenticity can be hard to identify in some assessments such as essay writing and homework.
