Student Growth Percentiles are a norm referenced growth
metric capable of being embedded within criterion referenced
assessment/accountability systems.
Student Growth Percentiles were developed by Dr. Damian
Betebenner at The Center for Assessment to help states use
their longitudinal assessment data to understand the progress
of students and its relationship to education quality.
Student Growth Percentiles have been adopted for use by four
states: Colorado, Massachusetts, Indiana, and Arizona and
are being piloted in many other states including Rhode Island
and New Hampshire.
The method formed the basis of the Colorado Department of
Education’s successful application to USED under the Growth
Model Pilot Program for use as part of AYP.

What are the relevant questions?
Growth models address specific questions
Different growth analysis techniques are good at
answering different questions.
It is critical to understand these different questions.
Different questions lead to different conversations which
lead to different uses and outcomes.
Questions form the vocabulary of later conversations
Starting with the right questions simplifies development
and motivating the proper use of the growth model results.
It’s all about the conversations you want to have. The
questions set the table for those conversations.

Are our students growing appropriately toward meeting
state standards?
Does this school/program show as much growth as that

Can I measure student growth even for students who do
not change proficiency categories?

summary conclusions?
