What are principles of validity?

What is fairness in learning?
In practice, fairness is often defined synonymously with equity. In educational testing, equity in the opportunity to learn and to demonstrate that learning is fundamentally valued and most often assumed during test construction, even where evidence suggests otherwise.
What is the importance of validity in assessment?
For that reason, validity is the most important single attribute of a good test.

Reliability is important in the design of assessments because no assessment is truly perfect. A test produces an estimate of a student’s “true” score, or the score the student would receive if given a perfect test; however, due to imperfect design, tests can rarely, if ever, wholly capture that score. Thus, tests should aim to be reliable,

However, validity is not a property of the test itself; rather,
How is the validity of a test determined?
There are other pieces of validity evidence in addition to reliability that are used to determine the validity of a test score. Of great importance is that the test items or rubrics match the learning outcomes that the test is measuring and that the instruction given matches the outcomes and what is assessed.
