What is PVAAS?
 Analysis of existing assessment data
 Longitudinal PSSA scores in available content areas
 Math, Reading, Science, Writing
 Provides reliable estimates
 A measure of a school’s effectiveness
 Critical Relationship:
Growth Data vs. Achievement Data
What PVAAS is not…

Is not another test
Critical concept

Is not a comparison of single
test scores
Achievement vs. Progress
 The final result of an academic
experience
 Is the concept underlying value-added
analysis and reporting
 Highly correlated with
demographic factors, such as
socioeconomic factors outside of
school
 Not correlated with demographic
factors
 Measures students’ performance
at a single point
 Compares student performance
to a standard
 Critical to students postsecondary opportunities
 Dependent upon what happens as a
result of schooling
 Measures students’ progress across
time/years
 Compares student performance to
his/her own prior performance
 Critical to ensuring students’ future
academic success

Definition:
A group makes one year’s growth when they
maintain their relative achievement level from one
year to the next in relation to the statewide
distribution (2006 baseline).

≈ 52.7 – 47.6 ≈ 5.1 NCE units
Predictive Methodology
Math & Reading – Grades 11
Writing – Grades 5, 8, 11
Science – Grades 4, 8, 11
Definition:
A group meets the growth measure when
their actual achievement meets their
predicted achievement - based on the
average schooling experience.
