Developer
This product was developed by the state of Pennsylvania.

Product Description
Initiated in 2002 and established in the summer of 2008, PVAAS is used with other measures to ensure that students are on track for learning. The system allows teachers to make informed decisions regarding instruction. PVAAS considers previous student achievement data and uses that information to make predictions on where students will be in the future. Pennsylvania adopted its particular form of value-added analysis based on the EVAAS system developed by William Sanders and his associates at the SAS Institute in North Carolina. SAS provides PVAAS data to all of Pennsylvania’s school districts. PVAAS provides districts with individual student and aggregated scores that compare actual performance on the PSSA mathematics and reading tests with what is called the “growth standard,” or how students with an average educational experience would have performed. A second component of PVAAS provides projections about the performance of students on future PSSA tests. Given its current state of development, PVAAS appears to be appropriate for low-risk (low-stakes) purposes, such as the identification of students requiring intervention and the initiation of discussions about curriculum or professional development. Generally, value-added assessment systems have been used in two ways: as an accountability measure and for professional/curriculum development. The Pennsylvania Department of Education has advised districts that PVAAS is not to be used for teacher compensation or evaluation. It is used for formative purposes.
