1 Pennsylvania Value-Added Assessment System (PVAAS) High Growth, High Achieving Schools: Is It Possible? Fall, 2011 PVAAS Webinar

2 Misconception: High achieving students/schools cannot show growth!

3 One Question: If PSSA is designed to discriminate proficient from non-proficient, how can it be used to calculate growth for students at the extremes? Fall 2011 PVAAS Statewide Core Team 3

4 About the PSSA Exams The PSSA is designed to discriminate proficient from non-proficient, and also to have sufficient stretch to discriminate between Below Basic, Basic, Proficient and Advanced. Other critical facts: There is NO ceiling on the PSSA! Each year, test scores are scaled using a lowest score of 700 and the previous years cut scores for the proficient category.. The high end is allowed then to be scaled based on the distribution of the data – not a fixed, pre- determined value. Fall 2011 PVAAS Statewide Core Team 4

5 My students are SO high achieving already… What is the reality of student performance on PSSA?

6 Fall 2011 PVAAS Statewide Core Team 6 Student NCE Scores in Mathematics 4 th Grade vs. 5 th Grade Each dot represents multiple students with the same scores.

10 How does PVAAS address growth for high achieving students and schools?

11 PVAASs Criteria for Tests Three conditions on assessments to be included in PVAAS analyses as required by the statisticians at SAS, Inc. 1. The tests must be aligned to curriculum standards. 2. The tests must be reliable and valid. 3. The tests must demonstrate sufficient stretch to show growth of low and high performing students. Fall 2011 PVAAS Statewide Core Team 11

12 PVAAS Checks for Stretch Number of different scaled scores at the top end and at the bottom end: Number of different scaled scores at the top end and at the bottom end: Sufficient to differentiate growth at both endsSufficient to differentiate growth at both ends Percentages of students scoring each score at the top end and at the bottom end: Percentages of students scoring each score at the top end and at the bottom end: Ensures no ceilings or floorsEnsures no ceilings or floors SAS, Inc. does these checks each year!

13 PVAAS Methodology Multivariate Longitudinal Mixed Effect Model (MRM) This type of model exploits the Covariance structure of the data points to dampen the error that is related to each measurement in the model. That is, the result of the modeling process, the estimated achievement (and therefore, the estimated gain), is more precise than any of the individual measures that are used as predictors in the estimation process. The whole is more precise than the sum of its parts! Fall 2011 PVAAS Statewide Core Team 13

14 So Can High Performing Groups of Students Show Growth? YES!!!

15 To Answer This Question… Two Sources of Evidence: 1.Actual Pennsylvania Scatterplots 2.School Search of Actual PA Schools Fall 2011 PVAAS Statewide Core Team 15

18 PVAAS School Search For our purposes: We will display actual school-wide data available on the PVAAS Public web site. We will display actual school-wide data available on the PVAAS Public web site. You can perform School Searches on the PVAAS secure site to allow you to view grade level results.

26 HIGH GROWTH A Visual Representation Fall 2011 PVAAS Statewide Core Team 26

27 Compacting Simulation Suppose we have a population of high performing students whose mean performances range from 85 to 100 (100 being the highest value). Suppose we have a population of high performing students whose mean performances range from 85 to 100 (100 being the highest value). What happens to the mean of these performances as we strive to move all students to higher performance levels? What happens to the mean of these performances as we strive to move all students to higher performance levels? Fall 2011 PVAAS Statewide Core Team 27

39 But, but, but… What if my school is high achieving but not showing acceptable growth? Remember: Advanced and Proficient categories are ranges – students can improve or slip within those ranges… PVAAS will document those changes.Advanced and Proficient categories are ranges – students can improve or slip within those ranges… PVAAS will document those changes.
