Abstract

In the context of measurement, reliability refers to consistency and stability of the scores, not the tests themselves, while validity refers to the
accurate interpretation of test scores (Reynolds, Livingston & Willson, 2009). The concern of reliability together with validity stems from the
original nature of assessment to provide precise information that helps educators make necessary changes to enhance the quality of education.
The

paper underlines that reliability and validity of this information is of great importance in decreasing the degree of measurement
error that is inherent in all measurement. Therefore, the role of educational professionals is to identify the sources of measurement error and
minimize their impact on the obtained sources. The research revealed that the teachers need to apply different approaches to eliminate the
sources of measurement errors and to estimate the reliability and validity of assessment in practice.
