Dunwoody Schoool Cluster Student Growth Model Data

**Updated with Excel Spreadsheet containing Dunwoody Cluster Subgroup Data.**


I have created an Excel Spreadsheet which contains the school level data reported by subgroup.  Click here to view that spreadsheet. For some reason, the spreadsheet loads more efficiently via Google Chrone.  Reminder these results are from the 2012-2013 school year. 

The Georgia Department of Education today released its Student Growth Model, the metric that will help educators, parents, and other stakeholders better understand and analyze the progress students make year to year. 

The department is also releasing a web tool, located at gastudentgrowth.gadoe.org, which will allow parents and members of the public to view visualized student-growth data.  Beware the bubbles!!!
  • Use the Search box to find your district, or click using the list provided. 
  • Click once on the model to choose the district.  
  • Double-Click twice on the district for a list of schools.
  • Use the Search box to find your school. 
  • Use the Pull Down options to enter data display options.
  • Toggle over the bubble to view data for the option chosen under "Perspective".



This data is based on the 2013 school year (CRCT for ES/MS Students and EOCT for HS students). Data reflecting 2014 school year student progress will be available in late fall. 

School and district growth scores are based on what are called “student growth percentiles.” Essentially, student growth percentiles are calculated for each student in each tested subject by comparing his or her standardized test scores at the end of one year to the performance of other students who had similar test scores to him or her in the past.

Schools and districts are given a “median growth percentile” that offers a sense of how much a typical student at the school grew in a year compared to his or her academic peers

The growth model uses two years of prior test data as pretest scores (one year is used when two years are not available). For example, growth percentiles for 5th-grade students on the 5th-grade CRCT are generated using 3rd and 4th grade CRCT results as priors.

To be honest, the amount of data is overwhelming.  Unless you love data, and I do not, you could spend hours reviewing and attempting to comprehend all of the data.  My assumptions could also be wrong. The massive amounts of documentation provided by the GADOE are many times unclear.

I used the AJC's tool to report the Dunwoody school cluster data.  Click here for the AJC database.   As time permits, I may summarize the data by subgroup.

Definition of "Academic Peer":  Academic peers are students enrolled in the same grade and content area or EOCT course statewide with similar prior academic achievement (academic history). In other words, they are students that had the same scores on prior state assessments. There are potentially thousands of academic peer groups – as many as there are prior score combinations. Students can be in different academic peer groups across subject areas and peer groups can change from year to year based on the most recent prior scores.
