District Evaluation Composites

This report lists the index values and levels for each district evaluation composite. The index is generated from the value-added results for each assessment included in that specific composite and takes into account the combined growth across all included assessments and the associated standard error. All district-level composites are single-year values and are calculated using data only from the most recent school year.

An effectiveness level is applied to each composite index using the following rules.

Effectiveness Level	Growth Index Value	Interpretation
Level 5 - Most Effective	2.00 or higher	Significant evidence that the district's students made more progress than expected growth.
Level 4 - Above Average Effectiveness	Between 1.00 and 2.00	Moderate evidence that the district's students made more progress than expected growth.
Level 3 - Average Effectiveness	Between -1.00 and 1.00	Evidence that the district's students made progress similar to expected growth.
Level 2 - Approaching Average Effectiveness	Between -2.00 and -1.00	Moderate evidence that the district's students made less progress than expected growth.
Level 1 - Least Effective	Less than -2.00	Significant evidence that the district's students made less progress than expected growth.

When an index falls exactly on the boundary between two levels, the higher level is assigned.

Educators using district-level composites for the growth component in the Tennessee Educator Acceleration Model (TEAM) select a district-level composite from the available options.

District-level Evaluation Composites are available for these test combinations:

TCAP (Grades 5-8)/EOC
CTE Concentrators
CTE Students
TCAP (Grades 5-8)
EOC

There are four composite types:

Overall
Literacy and Numeracy
Literacy
Numeracy

The Statistical Models and Business Rules of TVAAS Analyses lists the assessments included in each composite type for each test combination.
