What are the Grade Level and Readability statistics?

The Grade Level and Readability statistics shown in the editor give you some general information on the complexity of your writing.

For a comprehensive guide to understanding of the grade level and readability statistics, check out our blog article here.

  • Readability: A score indicating the reading ease of the document text; the higher the score the easier it is to read.
  • Grade Level: Indicates the number of years of schooling required to understand the document text; the lower the score the easier the document is to understand.

Note: the scores do not indicate quality or correctness of writing.

The two scores are directly linked to one-another; when your Readability increases, your Grade Level will decrease, and vice versa. Generally a lower grade level is actually better, as it means your writing is easier to read. If your Grade Level is too high, it usually means your writing is overly complicated. GradeProof aims to improve the expression of your writing by reducing complex phrases. You will often find after completing all the GradeProof suggestions, your readability will increase and your Grade Level will decrease.

The scores can be understood using the following table from Wikipedia:
