Description

A dataset comprising a subset of seven years of state assessment ELA and mathematics data across an 8 year span suitable for student growth percentile (SGP) and percentile growth projection/trajectory analyses. The dataset is missing 2020 data to help users model COVID related interuptions to student growth. The dataset is in LONG format with each record representing a unique student, by year by content area combination. The example data is used in examples and illustration in the enclosed documentation to show how SGPs 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 seven years (across an 8 year span) and two content areas for the following variables.

VALID_CASE

Indicator of whether the case is valid or invalid

CONTENT_AREA

Content area for student observation (ELA or Mathematics)

YEAR

Year for student observation

ID

Unique Student Identification Number

IEP_STATUS

Student Individual Education Plan status

GRADE

Grade level of student observation

SCALE_SCORE

Student Scale Score

ACHIEVEMENT_LEVEL

Achievement level associated with student scale score

PRIOR_SCORE_1_YEAR

Student scale score from 1 year prior (if available)

PRIOR_SCORE_2_YEAR

Student scale score from 2 years prior (if available)

ETHNICITY

Student ethnicity

FREE_REDUCED_LUNCH_STATUS

Student free/reduced lunch status

ELL_STATUS

Student English Language Learner status

GENDER

Student gender

SCHOOL_NUMBER

School number associated with student record

SCHOOL_NAME

School name associated with school number and student record

DISTRICT_NUMBER

District number associated with student record

DISTRICT_NAME

District name associated with school number and student record

Note

All datasets used with studentGrowthPercentiles and studentGrowthProjections must be specifically formatted as wide format files. The first variable/column is the student ID variable. The next set of columns provide the grade of the student across all the years provided in the dataset (possibly missing). The last set of columns provide the scales scores of the student in the respective grades. Operational users of this package are advised to use data formatted similar to the sgpData_LONG_COVID with the higher level functions prepareSGP, analyzeSGP, combineSGP, summarizeSGP, visualizeSGP, and outputSGP
