Why are scores that are based on averages poor indicators of student achievement?

While student effort is important, average scores typically reflect the overall performance on assessments rather than individual effort levels. Thus, this choice does not address the fundamental issue of how averages overlook the nuances of each student's learning journey.

Consistency in performance is indeed a factor in understanding student achievement; however, averages can still provide a generalized overview of a student's performance across various assessments. This choice does not directly address why averages are particularly poor at capturing the growth aspect of student learning.

Although motivation plays a significant role in student performance, average scores do not inherently capture motivation levels. Instead, the primary concern with averages is their inability to reflect the growth and progress students make over time, which is crucial for understanding true achievement.
