Teacher Diagnostic Summary Report

Understanding the Report

Growth

A simple growth measure is created for each achievement group. These values indicate the amount of academic growth students in the group made, on average, in the selected grade and subject or course. Use caution when interpreting these growth measures. Keep in mind that students are not weighted based on the teacher's instructional responsibility as they are for value-added reports. The values in this report are not the result of the statistically rigorous analyses that generate growth measures for the value-added reports. For more information, see Technical Details.

Color Coding

The slices of the chart are color-coded to indicate whether the data suggests that students in each achievement group exceeded, met, or fell short of expected growth. You'll find a legend for the color coding at the bottom of the report.

For information about interpreting the charts, see Interpreting the Data.

Diagnostic Color	Growth Measure Compared to Expected Growth	Interpretation
Light Blue	At least one standard error above	Moderate evidence that the students made more growth than expected.
Light Green	Between one standard error above and one standard error below	Evidence that the students made growth as expected.
Light Red	More than one standard error below	Moderate evidence that the students made less growth than expected.
White	N/A	Not enough students to generate a growth measure.

Standard Error

All growth measures on the TVAAS reports are estimates. All estimates have some amount of measurement error, which is known as the standard error. This value defines a confidence band around the growth measure, which describes how strong the evidence is that the group of students exceeded, met, or fell short of expected growth.

For more information about standard errors, see Growth Measures and Standard Errors.

Student Count

These rows list the number of assessments in each group.

For more information, see Technical Details.

Percentage of Students

These values represent the percentage of this teacher's students who were in each achievement group. For example, if the teacher taught a relatively large number of higher-achieving students, the percentage for that group would be larger. If the teacher taught a relatively large number of lower-achieving students, the percentage for that group would be larger.

Achievement Groups

For information on how students are placed into and excluded from achievement groups, see Technical Details.

Filtering by Student Group

By default, the report includes all students the teacher taught in the selected grade and subject or course. You can use this filter to view the report for a subset of students.

To filter the list of students included in the report, click Filter by: Student Group above the graph. In the Student Groups window, you can choose any combination of race, gender, and demographic groups.

If you choose more than one group within a category, the report includes students who are in either group. For example, if you choose Black or African American and Hispanic, the report includes both Black/African American students and Hispanic students.

If you choose multiple groups across categories, the report includes only students who are in the selected groups in all categories. For example, if you choose Male and Students with Disabilities, the report includes only males who are identified as students with disabilities.

When you are finished making selections, click Submit. The report includes only those groups of students you selected.

Even when viewing a filtered group of students, placement of students into the achievement groups is still based on students' relative achievement to students statewide in the selected grade and subject or course.

To remove a demographic from your list of filters, click the X next to the demographic. To remove all demographic filters at once, click Student Groups. In the Student Groups window, click Clear and then Submit. The report now includes all students in the selected grade and subject or course.
