OD APPLICATIONS IN DEVELOPMENTAL SETTINGS: AN ADDENDUM ABOUT SUCCESS RATES Available to Purchase

Evaluative studies of OD applications 1950–86 generated an earlier panel of 100 applications with a substantial success rate, and this article reports that extending the period of observation in economically‐developing countries does not require substantive modification of that estimate. Additional cases were sought during the 1987–1993 interval, to augment the 30‐plus year period underlaying the original panel. The augmented panel has been enlarged by approximately 20 percent—from 100 to 121 cases of applications.
