TRANSCRIPT
PVAAS(The Pennsylvania Value Added Assessment System )
PVAAS IS:
• Another tool we can use to look at our school data
• A way to determine if students made one year’s worth of growth
• When combined with PSSA scores, we get a clearer picture of school achievement
PVAAS is NOT:
• Another Test; the data is taken from the PSSA
• A measure for teacher accountability
Things to Keep in Mind• PVAAS does not take into account a
student’s starting point. It looks at growth over a year.
• PVAAS measures growth, not AYP level
• A Scatter Plot graph combines both

Value-added Measure of Cohort Growth
• Comparison to a State Growth Standard
• The Growth Standard specifies the minimal designated academic gain from grade to grade for a cohort of students.
• The use of a Growth Standard creates the possibility that ALL schools can demonstrate appropriate growth.

PVAAS Value-added Cohort Growth Descriptors
Favorable Indicator
Estimated gain at or above growth standard. Students in this cohort have made at least one year growth.All schools can achieve this rating.
Caution Indicator
Estimated gain below growth standard but by less than one standard error.Students in this cohort have grown less than the standard.
Stronger Caution
Estimated gain below growth standard by more than one but less than two standard errors.Students in this cohort have fallen behind their peers.
Strongest Warning
Estimated gain well below growth standard by more than two standard errors.Students in this cohort have made little progress.

PVAAS School Report
This is an example of a School Value Added Report.
•It shows us growth by grade level.
•We can also use the chart at the bottom of the page to see growth of the same cohort over time.
Looking back
This chart is an example of a school performance diagnostic report•We can see the growth for groups of students
•The green line is at zero. This is the growth line.
•Everything at or above the line shows that the students have made one year’s worth of growth.
•Everything below the green growth line shows that the students slipped from last year. (They did not remain in the same position as last year)
