What is Value Added?
• Value added is a measure of teacher and school effectiveness.
• Unlike a state achievement score, value-added isolates and communicates educators’ impact on students’ learning.

Why Use Value-Added?
Using value-added along with other data allows us to separate…
what we think is happeningfrom
what is actually happening.

TPS Value-Added Reporting
• Available now for 2009-2010 and 2010-2011.
• Used for information, analysis and improvement.
• Training provided in the methodology and use of the data. – Principals: June, August and October of 2011– Teachers: October 2011
• Supported by Value Added Research Center (VARC) of Univ. of Wisconsin and Battelle for Kids.

Value-Added Model.
© 2011, Tulsa Public Schools
How do we calculate Value-Added in the education context?• Calculate the gain of scale score points for students at each school
using a prior-test and a post-test.
• Use statistical models to eliminate the effect of external factors (starting point, student demographics, etc.)
• Schools where students are growing faster than average are High Value-Added.
• Schools where students are growing slower than average are Low Value-Added.

What Do We Do With Value-Added Data?• Evaluate the effectiveness of
– Instructional practices– Programs
• Identify pockets of excellence to replicate
• Detect and respond to ineffective practices and programs

Control Factors
The VARC/TPS model uses statistical techniques to separate the impact of schooling from other factors that may influence growth. The following are the controls used in the model:
It is important to note that controlling for demographic characteristics does not mean lowering expectations for any grouping of students addressed by the control variable.
