Gewertz, C. (2018, September 20). Does Too Much Credit Recovery Lead to Inflated Graduation Rates? Retrieved January 17, 2019

Researchers found that while only 1 in 13 students is served by such programs, they are concentrated in schools with more students who are minorities and from low-income families.
