The bill establishes a prohibition against school districts in Iowa from implementing standards-based grading for students in grades six through twelve. Standards-based grading is defined within the bill as a method of evaluating student performance that breaks down traditional academic subjects into smaller learning objectives or skills, assessing students based on their mastery of these specific objectives.

This legislative measure aims to standardize grading practices across school districts by eliminating the use of standards-based grading in the specified grade levels. The bill does not include any amendments to existing laws but introduces a new section that clearly outlines the prohibition and provides a definition of standards-based grading for clarity.
