The “Greene Method” of calculating school “graduation rates” and the Manhattan Institute (MI) criticisms of official graduation and completion statistics are outlined and scrutinized. The methodology fails to recognize the complexity of the issue and appears to ignore the considerable efforts that have been undertaken by education statisticians to remediate the problems inherent to these types of data. The Greene method for calculating completion ratios is simulated and found to have little to no reliability. It is recommended that anyone intent on reporting valid and reliable education indicators avoid use of the Greene Method.
