This paper presents an analytical approach, based on rank statistics,
to the issue of comparing programs within Data Envelopment Analysis (D
EA) efficiency evaluation framework. The program evaluation procedure
distinguishes between managerial and programmatic inefficiency and use
s the Mann-Whitney rank statistic to evaluate the statistical signific
ance of the differences observed between a treatment program and its c
ontrol group program after adjusting for differences in managerial eff
iciency between the programs. A numerical example, based on the data u
sed to evaluate the educational enhancement of the Program Follow Thro
ugh, is used to illustrate the proposed statistical procedures.
