The significance of test validity, test reliability, task interactiveness, test attentiveness, test impact, and test practicality have been employed to improve educational practices. The researcher has considered the validity and reliability as severe concerns for the issues in question and the review has been advanced to add to the understanding of the former’s value in designing a writing test. Desktop reach formed the base of this research. The search confirms that the aforementioned characteristics are central to the design. This confirms with the research findings available in the literature of teaching and testing.
