Why Did We Become Educators? To make a difference in children's lives
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 happening from 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.

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
Which Grades/Courses Have Value-Added Reporting at TPS? Math (4-8) Reading (4-8) Science (5, 8) Social Studies (5, 8) Writing (5, 8) Geography (7) English II, III Algebra I, II Geometry Biology I U.S. History
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: Prior OCCT Score Grade Level Gender Race/Ethnicity Low Income Status ELL Status Special Education Status Mobility (Continuous Enrollment) Attendance History Grade Retention 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.
