When turning in my SLO data, I like to visually see student progress throughout the year. Here are my SLO reports from this year. I blurred the student names for privacy reasons...but you can see the different colors and how I presented the data. (My pre-assessment and post-assessment tests have been posted previously on this site. Just do a search for SLO.)
The colored names on the left show student learning levels after the pre-assessment. The names on the right show the current level of the student after the final assessment.
