A Two-Part System
1. Holistic Schoolwide Performance
– The West Virginia Accountability Index
– Multiple measures
– Considers growth and relative performance
2. Subgroup-Specific Performance
– Annual Measurable Objectives (AMOs)
– Proficiency rate expectations for subgroups
How are these applied?
• School context considered throughout:
– Every school gets its own starting point
• All schools have the same expectations
– Every school has the same end point (75% of all
students proficient by 2020).
– Every school gets its own trajectory (ex. 2012= 35%
Proficient; Need to gain 40 percentage points over the
next 8 years.)
– Rates of progress
• Higher performing schools are expected to continue
increasing
• Lower performing schools must improve at faster rates
What is the First Part?
The West Virginia Accountability Index (WVAI)
• Multiple measures
– Achievement
– Achievement Gaps
– Growth (Adequate and Observed)
– Graduation Rates/Attendance Rates
What is the First Part?
The West Virginia Accountability Index (WVAI)
• Achievement
– Math and Reading
What is the Second Part?
The West Virginia Accountability Index (WVAI)
• Achievement Gaps
– An average achievement gap across all subgroups
in a school
– N size of 20
– Subgroup vs. Non-subgroup membership (low-SES
vs. non-low-SES)
The West Virginia Accountability Index (WVAI)
• Growth
– Are students demonstrating growth right now?
(Observed)
– Are students on track to be proficient in three
years or sooner? (Adequate)
The West Virginia Accountability Index (WVAI)
• Graduation/Attendance Rates
– Attendance rate:
• How close is your attendance rate to 100%?
• Attendance rate no longer is a pass/fail
– Graduation rate:
• How close is your graduation rate to 100%?
• Graduation rate no longer is a pass/fail
How the Index
Components Fit Together
• Each of the WVAI components (achievement,
gaps, growth, graduation/attendance rates)
add up to a WVAI Index Score
• Each school has a unique Index Score
• Each school (within a programmatic level) has
the same target
• Each school has its own trajectory

The WV Growth Model:
Our Purpose
• To provide an answer to a few
common questions:
1. “How much did my student grow this
year?”
2. “What does this growth mean
compared to everyone else?”
3. “Is it enough growth?”
What do these three questions have in common?
Information about students
Status vs. Growth
• Before growth, let’s review terms
– Status: A snapshot measure of a single
point in time – “Proficiency”
– Growth: Multiple snapshots across many
points in time
Measuring Growth: A Primer
• Uses all available data to answer three
questions:
– Am I proficient?
– How much did I grow?
– Is it enough growth?
• The WV Growth Model yields:
– Student Growth Percentiles (SGPs)
• What are SGPs?
– How much did students grow compared to
everyone else?
What is a Student Growth Percentile?
• Given (3 things):
– A student’s prior scale scores
– Academically similar students
– Current scale score
• A student’s current scale score represents a
percentile of growth – a Student Growth Percentile
• Think of it as the probability of a student’s current
achievement based on their past achievement:
• Growth percentiles describe the probability/rarity
of a student’s current achievement based upon
their prior achievement.

Measuring Growth: A Primer
• What is the likelihood of current (and
future) performance given past
performance?
• Based on students who have similar
academic histories (academic cohort)
• Uses all available data to answer those
three prior questions:
– Am I proficient? (Status)
– How much did I grow? (SGPs)
– Is it enough growth? (What growth needs
to occur?)
Our Growth Options (Primer, cont’d)
• How much growth? – Starts with the student.
Can be aggregated to drive school
conversations
– Low Growth (bad surprises)
– Typical Growth (a statistical expectation)
– High Growth (good surprises)
• Is it enough growth? – Can drive student
learning conversations
– Catching Up
– Keeping Up
Why do we care?
• Why growth? 4 Driving Questions
1. How much growth did my student
exhibit?
2. What does this growth mean?
3. How much growth does my student need
to be proficient in the future?
4. How likely is this growth?
• Student Reports – the primary benefit
