Scatterplots

This report enables you to create graphs that display the relationship between two variables. For example, you might choose to view the relationship between entering achievement and growth in sixth-grade math for all schools in a district. Using the options in this flexible report, you can:

  • Choose the variable for each axis in the graph
  • Select the districts, schools, or teachers to plot
  • Filter the results by demographics

  • Customize the way the data is displayed

Building scatterplots can be a powerful way to explore the data because it enables users to see whether relationships exist between two variables or types of data, such as achievement and growth. Both achievement and growth must be considered together to get a complete picture of student learning. Achievement information indicates where students are academically, at a given point in time, while growth information indicates the amount of academic progress students have made. The scatterplots enable you to view both pieces of information simultaneously to examine their relationship and identify patterns that can provide insight into the effects of educational practices on student learning.

In grades 3–8 in 2015–16, the state of Tennessee suspended testing for mathematics, English language arts, science, and social studies. Therefore, scale scores are not available for these assessments. As a result, the 2016–17 and 2017–18 TVAAS reporting in grades 5–8 for mathematics, English language arts, and science does not include 2015–16 test scores.
