How are school grades determined?

The determination of school grades based on the number of points earned from nine measures of achievement is a comprehensive approach that incorporates various aspects of student performance. This method typically includes a range of quantifiable metrics, such as standardized test scores, student academic growth, graduation rates, and other relevant indicators. By utilizing multiple measures, this approach provides a more holistic view of a school’s effectiveness in fostering student learning and development.

The focus on diverse achievement indicators helps ensure that a school is evaluated fairly and that all students' academic achievements are recognized. This system can also motivate schools to improve their performance across various domains, thereby enhancing educational outcomes for students.

In contrast, solely relying on student attendance, parent surveys, or teacher evaluations of student behavior would provide a limited perspective and fail to account for the many factors that contribute to a school's overall performance and student achievement. Thus, the multifaceted approach reflected in the correct answer highlights the importance of a well-rounded assessment of educational quality.
