Summer can be a costly time for low-income families. According to Jennifer Peck, Executive Director of the Partnership for Children and Youth, “While middle-income children retain knowledge or, in many cases, make gains over the summer, low-income children fall behind.” Summer learning programs are a cost effective way to prevent summer learning loss and close the opportunity gap. In order to better understand the cost of such investments, Summer Matters conducted a small survey of partner organizations offering high quality summer learning opportunities in California.
