From Mississippi Dept. of Education social studies framework, 2011.

Understand how technology, geography, and social conflict has impacted the development of the United States. d.Trace the origins and development of slavery; its effects on African Americans and on the nation‘s political, social, religious, economic, and cultural development; and identify the strategies that were tried to both overturn and preserve it. (DOK 2) e. Analyze the causes, key events, and consequences of the Civil War. (DOK 3) f. Evaluate and examine the Reconstruction Era (using primary and secondary sources such as political cartoons, documents, letters, etc.). (DOK 3)

Civil Rights/Human Rights Understand the impact of American ideals and institutions on the development of American democracy. b. Study the lives of formerly enslaved African Americans who gained freedom in the North and founded schools and churches to advance their rights and communities. (DOK 2)

d. Research and analyze political and social impacts of civil rights movements throughout the history of the United States pre-Reconstruction era (e.g., slave revolts, abolitionist movement, protests over British taxation in the colonies, individual and group resistance, organizing efforts, and collective action/unity). (DOK 3)

Every teacher is different, and even the best teachers, everywhere, bring some kind of bias with them, for better or worse. The public school system I went to in Mississippi was close to 70% African American. How well do you think teaching the students that the South=slavery=good guys and the North=aggressors=bad would have gone over, even of the teacher really, really believed or to be true?

Edit: so bewildered by a question like this I had a hard time formatting and spelling.

The Georgia standards for the Civil War do not state that GA or any other Southern State was a "bad guy," but they do not argue that any leaders or states in the Confederacy were "good guys" either. Like current college-level historiography, K-12 education focuses on the lead-up to the Civil War in terms of the expansion of the United States in the West and the tension between regions based on slavery expanding into the newly acquired territories. You can see a high school framework for the Civil War for GA here. A framework is defined as " 'models of instruction' designed to support teachers in the implementation of the Georgia Performance Standards (GPS)."

Another instructional unit plan from GA shows similar thoughts: no bad guys, no good guys, just causes and consequences and battlefields and leading individuals before/during/after the war. This is actually a fairly interesting document because of its focus on specific pre-war events, leaders during the war, and battle campaigns, especially considering it is a unit designed for 5th grade (usually the final year of elementary school in Georgia).

Overall, it would appear that Georgia in K-12 teaches the Civil War in a rather neutral way. The central argument seems to be that rising tensions about state's rights and slavery between the North and South led to secession and then to war. Abraham Lincoln is admired, but leading Confederate generals aren't discounted because they led Southern troops. Standards focus on Reconstruction and the positive and negative outcomes of the war on both regions and whites as well as blacks.

Now, the way that teachers actually implement these standards might get a different answer, but it also would almost certainly be based on one's personal experience within Georgia's educational system, a topic which is not allowed in this subreddit.
