As of July 1, 2012 RCPS will no longer be coordinating Home School services.
Families must go through the Georgia Department of Education in order to annually submit a Declaration of Intent to Utilize a Home Study Program and for all other home school matters.  
Questions should be directed to the following people at the Georgia Department of Education:
Mr. Pat Blanke - 404-463-1765
Ms. Joyce Kelly - 404-656-2093 
Declarations of Intent and monthly Attendance forms should not be submitted to Rockdale County.
Students, parents and local home school associations may choose to immediately begin submitting their new home school required documentation electronically via HomeschoolCompliance.com (Mr. Scott Meadows – 706-353-3548). Neither Mr. Meadows nor HomeschoolCompliance.com are associated with the Georgia Department of Education; however, the Georgia Department of Education has entered into an agreement with Mr. Meadows allowing him to begin accepting this documentation prior to the July 1, 2012 start date in order to better serve those choosing the home school option.
  
Utilizing HomeschoolCompliance.com is free of charge until July 1, 2012.   Parents should check HomeschoolCompliance.com for fees after July 1, 2012.
