Here, from usefulcharts.com, are charts covering the easily-grasped type of info--details on stages from Piaget, Erikson, Kohlberg, and Fowler:
Will any/all of this show up on the social work exam? There's no saying for sure. Maybe Piaget, maybe Erikson. Less likely Kohlberg and Fowler. Depending upon how you read the ASWB outlines, all show up on any thorough could be list. Usual disclaimer: don't wear yourself out learning the details of this material.
