This is not exactly what you are looking for, Val, but this post on Willingham's blog discusses a recent meta-analysis of studies on the effects of retention. I'm linking the blog post rather than the articles because I often find Willingham's posts interesting and because I have read the post but not the articles.

I liked Willingham's book "Why Don't Students Like School: A Cognitive Scientist Answers Questions About How the Mind Works and What It Means for the Classroom".
