Validity is the notion of how well an assessment fits the data being tested and is judged upon its content, construct, criterion relationship, and consequences (Oerman, 2016). Reliability is the extent to which an assessment can be predictably repeated and is tested by how statistically similar repeated assessments compare. Practicality is the notion of how likely an assessment can be repeated due to circumstances like ease of administration, cost of the assessment and time constraints. This can be evaluated by looking at the method of delivery and seeing if it is a good fit for the curriculum in question.

Above is a link to an example online quiz regarding Strokes. Since it is a quiz, it can be regarded as a formative assessment. All of its questions are within the domain of CVA’s and their related causes, symptoms and treatment as well as the construct. Critereon relationship is strong because these questions are written in preparation for the NCLEX. Consequences appear to be standard as doing well on this quiz can likely mean better passing rates on the NCLEX. Each question is based on published evidence based practice, which likely means that results are likely repeatable and reliability is strong. There are 21 questions which could be statistically significant for an adequate sample size lending to its reliability. Being online, multiple choice and easily gradable, practicality of the quiz is extremely high. I believe that overall, this is a good example of an assessment with good validty, reliability, and practicality.

After reading this week’s discussion prompt, the first assessment that came to my mind is The 5 Love Languages, which is found here (Winston, n.d.): http://www.davidswinston.com/uploads/2/7/0/8/27080571/5_love_languages_test.pdf
Some may view this test as silly or invalid, but it’s been weighed in on by psychologists that have sad it was a ‘very useful tool’ and has been used amongst them during their couples therapy sessions (Duncan, 2021). What some would view as weakness is that it
