These kinds of enrollment falsifications are much more common and much more pervasive than most want to believe. I've seen exposés on secondary public school systems in major metropolitan areas engaging in the practice. It happens for a variety of reasons. Federal funding, career advancement for administration, etc.
Point is, when these things hit the news, often they prompt similar things to be "discovered" at others in an industry. It would hardly come as a shock if one of these evenings there was a similar item from COCO or one of the others hit the wires. Or maybe it was just CECO and nobody else in the industry's ever doctored enrollment. (yeah, right!)
