How should Assessment Series data be used?

This article is intended only for customers and partners using the Assessment Series.

CommonLit’s Assessment Series tests measure student performance on end-of-grade-level expectations in reading comprehension. Assessment Series data should be used to inform broad instructional decisions and adjustments.

Students’ Assessment Series scores should serve as one data point for teachers and administrators and should be interpreted alongside other information (e.g., other reading assessment scores, data from CommonLit lessons assigned throughout the school year) to make informed decisions about student progress.

Students’ assessment scores should not be used for high-stakes decisions or non-instructional purposes, including to evaluate teacher performance.
