Methodology,
Research & Statewide Data
SAS® EVAAS®
for K-12 provides value-added modeling and projection analyses for the
assessment of academic growth and to ensure students are on the path to
proficiency and beyond. This includes the PVAAS web-based reporting to
Pennsylvania’s public school districts, charter schools, cyber charter schools,
and full-time Career and Technology Centers.
The methodology used in
Pennsylvania for value-added assessment is based on the SAS® EVAAS®methodology,
called Education Value-Added Assessment System (EVAAS). More simple models for
value-added assessment (unlike SAS® EVAAS®) may yield results that may be
confounded by measurement error and exclude students who have missing data in
their assessment history. Pennsylvania’s implementation of EVAAS is called the
Pennsylvania Value-Added Assessment System (PVAAS). The EVAAS methodology has
been published since 1998 and has been nationally peer reviewed. Following a
pilot from 2002-2005, PVAAS has been implemented statewide in Pennsylvania
since 2006.
In addition to
Pennsylvania, SAS® EVAAS® for K-12 is involved in the
statewide implementation of district, school, and/or teacher-specific reporting
in Ohio, Oklahoma, Tennessee, Michigan, South Carolina, and North Carolina. SAS® EVAAS® for K-12 also provides statewide analysis of data in Arkansas
and Texas as well as analysis for several regional and district implementations
across the United States, including the District of Columbia Public Schools.
SAS® EVAAS® for K-12 has been involved with research on
the effectiveness of teachers as measured by value-added analyses for over 20
years.
