What does a "+" symbol indicate in quality ratings?

The "+" symbol in quality ratings signifies a High Grade classification. This notation indicates that an item or product possesses enhanced qualities that exceed the standard expectations. In many grading systems, such as those used in assessments of materials or products, a High Grade is typically above average and suggests a level of excellence in performance, durability, or other pertinent attributes.

The presence of the "+" denotes an aspiration toward superior standards, distinguishing it from merely satisfactory or average ratings. This allows consumers and evaluators to quickly identify products that offer superior performance or quality compared to their counterparts. Understanding this symbol can be crucial in making informed decisions regarding purchases or evaluations in various fields, particularly in insurance estimations where the quality of materials or services can significantly impact the overall assessment.
