RHODE ISLAND GROWTH ANALYSES USING PSAT

BACKGROUND
• Rhode Island’s switch from PARCC to RI-CAS/PSAT10/SAT leads to
changes in the way that growth is calculated.
• In general, SGPs are using a students’ current test scores combined with at
least one prior test score subject to the condition that scores come from
the same test taken at the same time.
• That is, test transitions like those happening in Rhode Island do not
prevent the calculation of growth. However, communicating how growth is
calculated across a test transition can be more difficult.
• This presentation provides an overview of due diligence analyses
conducted for PARCC to PSAT10.
BACKGROUND
• Despite the versatility of SGP analyses not requiring a common scale
across years, problems can arise with analyses.
• The most common problems are related to ceiling/floor issues on tests as
well as too few score points on which to calculate the 99 conditional
quantile curves.
• All source code associated with these analyses (no data) can be found on
the Center’s GitHub repository for Rhode Island analyses at: https://

PRELIMINARY ANALYSES
• All analyses using 2017 PSAT data ran without any analytic issues
• No ceiling or floor effects were observed in any of the analyses.
• No issues related to “granularity” of scale were observed.
• Analyses that combined data for which there was a 1 year gap with data
for which there was a 2 year gap indicated a large effect depending upon
which group the student belonged.
• Algebra I (2015) to PSAT10 Math (2017): Median 59
• Algebra I (2016) to PSAT 10 Math (2017): Median 42
