RHODE 2014-2015 SGP ANALYSES
NECAP TO PARCC TRANSITION
Damian W Betebenner
National Center for the Improvement of Educational Assessment
Providence, RI November 23rd, 2015
TOPICS FOR DISCUSSION
• Student growth review
• Analyses and diagnostics associated with the 2014-2015.
STUDENT GROWTH IN RHODE ISLAND
• Analyses conducted for rst time in 2008 and have been
performed annually since. Last performed for Fall 2013 NECAP
administration.
• Analyses conducted for both Mathematics and Reading.
• Student growth percentiles were calculated and used, particularly
as part of teacher evaluation work conducted under RttT.
• Student growth projections were calculated but not used as part
of accountability or reporting.targets for typical and higher growth
a year in advance.
fi
THE TRANSITION TO PARCC
• SGP analyses are norm-referenced and don’t require a vertical
scale to be conducted. Depending upon whether results are
disseminated, a likely cause of confusion: “How can you calculate
growth across two different tests?”
• Other PARCC SGP states we’re conducting analyses for:
Massachusetts, New Jersey, Colorado
• The Center conducted meetings with both SBAC and PARCC
consortium members discussing issues related to calculating and
using growth during assessment transitions.

CONCLUSIONS
• Correlations between prior and current were close to what
has been observed historically and suf cient for valid growth
analyses.
• Despite fears, there do not appear to be signi cant oor or
ceilings impacting growth analyses.
