school_growth_percentile: Calculate growth percenitle

In kippchicago/sqrpr: Chicago Public Schools School Quality Rating Policy metric calculations

Description

school_growth_percentile is the workhourse function that calculates school growth percentiles.

Usage

school_growth_percentile(.data, student_column = "studentid",
  grade_column = "grade", subject_column = "measurementscale",
  rit_column = "testritscore", term_column = "termname",
  dl_indicator = "iep", ell_indicator = "iep",
  school_indicator = "schoolname", truncate_growth = TRUE,
  fall_equate_scores = NULL, norms = nwea_cps_school_level_norms_2015)

Arguments

.data	a long format (i.e., combined) Comprehensive Data File
student_column	column that uniquely identifies students with respect to subject and term
grade_column	column that identifies grade levels
subject_column	which column identifies measurement scale
rit_column	column that identifes RIT score
term_column	identifies term name
dl_indicator	identifies diverse learner status
ell_indicator	identifies English Language Learner status
school_indicator	column that identifies school
truncate_growth	whether or not to truncate student growth at 1st and 99th percentiles Default is 'TRUE'
fall_equate_scores	either a data.frame of fall MAP results with columns 'studentid', 'measurementscale', 'testritscore', and 'grade', or 'TRUE' if your equateding all fall scores from fall-to-spring map data. If a data.frame is passed, then these data are used to equate missing pre-test (i.e., prior-spring) RIT scores per CPS guidelines. IF 'TRUE' is passed, then all fall scores are equated to the prior spring

Details

Currently this function (indeed, this package) only supports spring-to-spring calculations. Since CPS will equate your fall scores anyway, this function does support equating fall to prior spring scores. see the 'fall_equate_score' parameter below for more details.

Value

list with four data frames attached showing student-, grade-, and school-level growth percentiles as well as the original data.
