Which of the following assessment tools is used to measure student progress?

Standardized tests are designed to provide a consistent measure of student progress across various educational institutions and demographics. These assessments are structured to evaluate a student's knowledge and skills in relation to a predefined set of standards or benchmarks. They offer quantitative data that can be analyzed to gauge individual and group performance over time, reflecting how well students have mastered the curriculum.

Unlike standardized tests, social media engagement does not provide direct insight into a student's academic progress or learning outcomes. While social media can foster communication and community, it is not a reliable assessment tool for measuring academic achievement.

Similarly, teacher observations, while valuable for understanding student behavior and engagement in a classroom context, are often subjective and can vary greatly from one teacher to another. This subjectivity can limit their effectiveness as a standardized measure of progress.

Class participation can enhance learning experiences but, like teacher observations, it lacks the rigorous structure needed for assessment purposes. It does not provide comprehensive data about a student's overall academic performance but rather reflects engagement in a specific classroom setting.

Thus, standardized tests stand out as the primary tool specifically designed and recognized for measuring student progress in a reliable and consistent manner.
