About Me
Dr. Damian Betebenner, PhD
- Senior Associate at the Center for Assessment (NCIEA).
- Developed student growth percentiles and percentile growth
trajectories to help states and educational associations employ
student growth in decision making [Betebenner, 2008,
Betebenner, 2009, Betebenner, 2012].
- Currently refining and sharing these techniques with other
states including Colorado, Massachusetts, Indiana, Nevada,
Hawaii and 25 other states in various stages of
investigation/adoption.

Student Growth Percentiles
2007 Began develop of the Colorado Growth Model (student
growth percentiles).
2008 Began work with Indiana on development of growth model.
2008 Successfully application of Colorado Growth Model
(criterion-referenced component) as part of growth model
pilot program.
2009-2010 Began/continued work with approximately two-dozen other
states on developing state growth models.
2010 Worked with states on incorporating growth into RttT
applications and with successful states on their use
(Massachusetts, Georgia, New York, Rhode Island).
2011 Worked with a number of states on incorporating student
growth percentiles into the ESEA waiver applications and
teacher evaluation systems.

About the growth model
The Student Growth Percentiles Methodology is a norm- and
criterion-referenced growth analysis method.
The norm-referenced component of the model is the student growth
percentile which indicates the relative growth a student makes.
The criterion-referenced component of the model is the student
growth percentile target which indicates the amount of growth
required by the student to reach/maintain desirable achievement
goals in a specified time frame. For example, catching-up to
proficiency within 3 years.
The norm- and criterion-referenced components together allow
stakeholders to understand what is, what should be, and what is
reasonable simultaneously.
The goal of the metric was to assist states to move beyond debates
over what thermometer is best to discussions of how best to use the
thermometer.

Built to maximize sharing
A number of analytic tools (for doing calculations) and visualization tools
have been developed with the goal to promote maximum sharing. Data
isn’t valuable! It’s what one does with data that is potentially valuable!
The analytic tools to calculate all the quantities associated with
student growth percentiles are open source and freely available to
all states.
The visualizations associated with student growth percentiles are
open source for non-commercial use.
Conduct training sessions at national conferences to help other
calculate these quantities (like Indiana) on their own.
Build enhanced visualization and reporting systems to make data
come alive to stakeholders and lead to better stakeholder
engagement with data.
