Identify the goals of Reconstruction and evaluate whether they were accomplished in the 12 year that the North occupied the South?

The previous post is correct in that there might have been specific points that your instructor would want you to obtain.  This should be the first reference point.  In the overall understanding about Reconstruction, the fundamental premise is what form post- Slavery society was to have taken after the Civil War.  Part of this was to have a closer and shared identity between North and South, as opposed to the schism which led to the Civil War.  In addition, the role of states' rights still presented itself, as Southern States were allowed to exercise their own autonomy in enforcing Jim Crow Laws to continue a segregated society.  While this was not a goal of Reconstruction, ensuring "malice towards none" did permit a sense of tolerance about ensuring legal equality for people of color and not mandating the social form of equality.  Certainly, this would not disparage the legal equality status achieved for people of color in specific relations to Amendments 13, 14, and 15 in the Constitution.
