Is CommonLit’s Assessment Series valid? 

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

The Assessment Series provides a valid and reliable measure of student reading comprehension. More specifically, the Assessment Series is designed to measure how well students understand and analyze texts according to end-of-year grade-level expectations.

Valid uses of Assessment Series data include:

• measuring student reading comprehension and text analysis at three points in the year in order to measure student growth
• providing information that, alongside other sources of data about students, can help inform educators' instructional decisions
• comparing students' performance over time, as well as comparing performance across classrooms and schools

In order to create valid assessments, all Assessment Series content is carefully developed, reviewed, and field tested to ensure that tests provide an accurate measure of student reading comprehension. Additionally, research has revealed promising correlations between students' scores on the Assessment Series and their performance on end-of-year state tests in New York and Florida.
