1. PVAAS – Pennsylvania Value-Added Assessment Systemhttp://www.portal.state.pa.us/portal/server.pt/community/pa_value-added_assessment_system_(pvaas)/8751

2. The TWO PVAAS Methodologies Looking Forward/Planning… PVAAS Projection Reports For Individual Students and Cohorts of Students Looking Back/Evaluation… Value-added Growth Reports For Cohorts of Students Today NO individual student growth measure

3. PVAASIS: • A statistical analysis of existing assessment data (PSSA). • A realistic measurement of a school’s progress/growth over time. • Progress data to add to achievement data as schools are analyzing their work with students and making improvement plans.

4. PVAASIS NOT: • Another test. • A method for providing a measure of growth for an individual student.

5. Current Data Collection Approaches High Achievement Average Achievement Low Achievement Achievement is based on each student’s ending point.

6. PVAAS Adds Another Variable To Achievement…Progress Below Growth Standard At or Above Growth Standard Progress is based on each student’s starting point.

7. Viewing Achievement and Progress Together Scatter Plots

8. Scatter Plot Quadrants and Their Meanings Achieving but Slipping Excelling Underperforming and Slipping Underperforming but Improving

22. 11th Grade Scatterplots The PSSA-PVAAS Scatter Plots visually display the following data from the statewide distribution of PSSA results for 2009-10: • Achievement • The mean predicted performance of the cohort. • The actual mean performance of all students in the state is displayed for reference • Growth • School Effect ≈ Observed Mean – Predicted Mean • Standardized School Effect = School Effect relative to its error – displays degree of confidence The following two slides explain the meaning of each of the regions of an 11th grade scatter plot.

27. Overview of PVAAS Reporting

28. PVAAS Reporting • District Level Reporting • School Level Reporting • Grade Level Reporting • Reading (Grades 4-8, 11) • Math (Grades 4-8, 11) • Science (Grades 4, 8, 11) • Writing (Grades 5, 8, 11) • Subgroups Reporting (ex. IEP, ED, ELL) • Performance Levels (Advanced, Proficient, Basic, Below Basic) • Student Level Reporting • Reading, Math, Science, Writing (grades vary based on content area)

29. Have all of our groups of students experienced one year of academic growth during the last school year? Value-added Growth Reports

33. How are our best students, our average students, our struggling students growing? Performance Diagnostic Report

34. Growth Standard MethodologyWhat the whiskers tell us… Exceeded Growth Standard; More than One Year’s Growth Green Met the Growth Standard; Made One Year’s Growth Yellow Growth Standard (One Year’s Growth) Below Growth Standard; Less than One Year’s Growth Rose

35. Predictive MethodologyWhat the whiskers tell us… ABOVE Expectations -- Observed Score Was Greater Than Predicted Score NDD – No Detectable Difference Between Observed Score and Predicted Score Observed – Predicted (One Year’s Growth) BELOW Expectations -- Observed Score Was Less Than Predicted Score

38. What is the likelihood that a student will be proficient on a future PSSA exam? PVAAS Projections

39. Student Projection Methodology • A separate longitudinal modeling process focused on the performance scores of individual students. • The model uses all of the available data (both math and reading) to project future PSSA performances in Math, Reading, Science and Writing. • Projections can be calculated for an individual student or groups of students.
