I know there are many books on evaluating academic success and deficits, but how do you evaluate social/emotional learning? Are there studies to help with this? What milestones should a parent look for? Should the amount of schooling in the younger years be factored into the evaluation as the child started learning social skills at a younger age?
I don't know if this will help you, but I found a study published online from January 2011 for the Raikes Foundation entitled "Social-Emotional Learning Assessment Measures for Middle School Youth". I know it seems to focus primarily on middle school ages, but it seems to have some information in it that talks a little bit about social-emotional assessment in younger ages, and it includes several samples of assessments towards the end. The reference page is a solid two pages, so there might be some literature in there that would help you some. Fair warning: It's about 50 pages long so you might want to settle in with a big cup of coffee after the kids have gone to bed :-D
