Which proficiency mark range indicates below average performance?

The range of proficiency marks that indicates below average performance is from 0 to 1.9, which signifies a level of performance that fails to meet the basic expectations. In proficiency evaluations, marks are typically designed to provide a clear distinction between levels of performance. Scores in the range of 0 to 1.9 indicate severe deficiencies and a lack of fundamental skills or competencies necessary for the given role or task.

The range from 2.0 to 2.9 represents a more marginal performance that might meet some requirements but still falls short of achieving the standard. The range from 3.0 to 3.9 reflects a satisfactory level of performance, while the range from 4.0 to 4.9 denotes above-average to excellent performance. Thus, the clarity of these ranges helps effectively measure and communicate an individual's capabilities.
