Do I have to grade the diagnostic?

No, teachers do not have to grade anything for the CommonLit Diagnostic. As soon as your students submit their tests, we will provide you with their overall scores and multiple-choice percentages per standard. Please note that students do not see their diagnostics once they submit, and we do not share their scores with students.

You will not immediately see your students' Percentile Rankings. This is because we recalculate percentile scores nightly to account for that day's submissions. Furthermore, we also only calculate and display percentiles and performance groups once we have collected a sufficient amount of valid data for your students (meaning enough CommonLit students in the same grade also took the same test). You will receive a message in your notification bell once this comparative data is available for you to view.

Please note that the CommonLit Diagnostic is meant to assess students' strengths and areas for growth at the beginning of a teaching period, and we discourage including students' Diagnostic scores in their overall class grade. Should you choose to share a Diagnostic score with students, we recommend you do so solely to set goals for improvement, and not as a formative or summative assessment.

Note: If your district has chosen to purchase Assessments Series in CommonLit School Essentials or CommonLit School Essentials Pro, you will not have access to the Diagnostic feature on CommonLit.org. Instead, you'll be able to collect baseline data through the first assessment in the Assessment Series.
