Description

Function used to produce individual student growth and achievement chart (an achievement time lines indicating student growth) based upon output from student growth percentile and student growth projection analyses. Function is integrated with SGPstateData to accommodate state specific scales and nomenclature including performance level names. See Betebenner (2012) for discussion

	Plotting_Scale_Scores, 
	Achievement_Levels, 
	SGP, 
	SGP_Levels, 
	Grades,
	Content_Areas,
	Cuts,
	SGP_Targets,
	SGP_Scale_Score_Targets,
	Cutscores,
	Report_Parameters)

Arguments

Scale_Scores

A vector of historical scale scores.

Plotting_Scale_Scores

A vector of scale scores used as the vertical coordinates for plotting. If supplied, Scale_Scores are used for text and Plotting_Scale_Scores are used for the actual coordinates.

Achievement_Levels

A vector of historical performance levels.

SGP

A vector of historical student growth percentiles.

SGP_Levels

A vector of historical growth (SGP) levels (e.g., low, typical, high).

Grades

A vector of historical grades student was tested in.

Content_Areas

A vector of historical content areas student was tested in.

Cuts

A list of cuts scores for NY1, NY2, and NY3.

SGP_Targets

A list of CUKU, CUKU_Current, MUSU, MUSU_Current targets.

SGP_Scale_Score_Targets

A list of CUKU, CUKU_Current, MUSU, MUSU_Current scale score targets.

Cutscores

A data.frame of long formatted achievement level cutscores.

Report_Parameters

A list containing arguments: Current_Year, Content_Area, State, Denote_Content_Area, SGP_Targets, and Configuration.

Value

• Returns a student growth plot graphical object that is usually exported in either PDF or PNG format.

Details

Function currently used as part of SGP package to produce student growth charts for states. Function is usally called from the higher level function visualizeSGP which allows for the creation of a student growth plot catalog for each school with student reports organized by grade and student name.
