sgptData_LONG R Documentation
Longitudinal Student Assessment Data in LONG format with DATE for SGPt analyses.
Description
A dataset comprising a subset of 3 years (and time periods) of interim assessment early literacy, reading and mathematics data suitable for time dependent student growth percentile (SGPt)
and percentile growth projection/trajectory analyses. The dataset is in LONG format with each record representing a unique student, by
year/time period by content area combination. The example data is used in examples and illustrations in the enclosed documentation to show how SGPts can be operationalized
across years with the results being used to produce a variety of high quality visualizations both at the aggregate (e.g., school) and individual level.
Format
A data frame of student level observations for five years and two content areas for the following variables.
COUNTRYVariable indicating the COUNTRY associated with test record.
STATEState associated with the test record.
VALID_CASEVALID_CASE variable.
CONTENT_AREAVariable indicating content area associated with test record.
YEARVariable indicating the year associated with the test record.
DATEVariable indicating the year associated with the test record: Must be in YYYY-MM-DD format.
IDUnique student identifier associated with test record.
GRADEVariable indicating the grade associated with the test record.
SCALE_SCOREVariable providing the scale score associated with the test record.
SCALE_SCORE_RASCHVariable providing the Rasch score associated with the test record.
SCALE_SCORE_CSEMVariable indicating the standard error of measurement associated with the scale score.
SCALE_SCORE_RASCH_CSEMVariable indicating the standard error of measurement associated with the Rasch score.
ACHIEVEMENT_LEVELVariable indicating the achievement level associated with the scale score.
