Bradford Indicator

Definition

This is a formula, devised by the University of Bradford, to take account of the disruptive effect of frequent short absences as well as long-term absence. The Bradford Index Formula is: S x S x D = (INDEX) Where S is the Number of occasions (Spells) of absence and D is the Total number of Days absent. For example: Five absences of one or two days (2 +1+2 +2 +1) gives S = 5, and D = 8 Thus (5 x 5 x 8) = 200 A single long absence of six weeks (30 days) scores 1 x 1
