Big Ideas About Data Analysis: 2013 CRCT Performance Index Honor Roll

By Derrick Brown (follow on Twitter @dbrowndbrown)


2013 CRCT Performance Index Honor Roll

We have analyzed and synthesized school-level results from Georgia's 2013 Criterion-Referenced Competency Test (CRCT).

The Georgia DOE published results from its system-level analysis on June 25, 2013.


Our Approach

We analyzed all 1800+ Georgia schools whose students took the CRCTs using the following two measures:

Performance Index = Sum of schoolwide "meets & exceeds" rates for each of the 5 CRCTs (English & Language Arts, Math, Reading, Science, and Social Studies)

Gain (Loss) = Sum of the increase (decrease) of schoolwide "meets & exceeds" rates for each CRCT


Data => Information

Several key findings regarding independent startup charter schools emerged from the data ...

Performance Index (Overall)

1. 4 independent startup charter schools ranked among the top 100 schools in Georgia in 2013 CRCT overall performance index (SEE TABLE 1 BELOW):

LAKE OCONEE CHARTER (7)
Museum School Avondale Estates (40)
Fulton Sunshine Charter Elementary (43)
Charles R. Drew Charter School (93)

2. 10 independent startup charter schools ranked among the top 100 schools in Georgia in 2013 CRCT performance index comparison (difference between school's performance index, and the average performance index for other schools in its local comparison district) (SEE TABLE 2 BELOW):

LAKE OCONEE CHARTER (4)
Museum School Avondale Estates (9)
Charles R. Drew Charter School (20)
Neighborhood Charter School (21)

Heritage Preparatory Academy School (5)
Lanier Career Academy (17)
KIPP VISION (23)
Georgia Connections Academy (49)
Ivy Preparatory Academy for Girls at Kirkwood (94)

4. 5 independent startup charter schools ranked among the top 50 schools in Georgia in one-year CRCT performance index gain comparison (difference between school's one-year performance index gain, and the average one-year performance index gain for other schools in its local comparison district) (SEE TABLE 4 BELOW):

Heritage Preparatory Academy School (5)
Lanier Career Academy (15)
KIPP VISION (21)
Georgia Connections Academy (35)
Ivy Preparatory Academy for Girls at Kirkwood (44)

KIPP VISION (18)
Coweta Charter Academy (24)
Fulton Leadership Academy (28)


6. 4 independent startup charter schools ranked among the top 20 schools in Georgia in two-year CRCT performance index gain comparison (difference between school's two-year performance index gain, and the average two-year performance index gain for other schools in its local comparison district) (SEE TABLE 6 BELOW):

Lanier Career Academy (2)
