The Bradford Index Factor is a simple calculation sometimes used in Human Resources as one measure of employee absenteeism.

The Bradford factor is an absence-oriented key performance indicator (KPI) designed to put a number behind the disruptive potential of 'one-off' absences when taken together.

The Bradford factor is designed on the assumption that short-term absences are more disruptive for an organisation than long-term ones, like a planned vacation.

The Bradford Factor is not universally accepted; especially if used to discipline employees since it takes no account of individual circumstances. However, as one indicative measure of overall absenteeism it appears to have support.

The number of Bradford points that trigger an absence review varies widely among employers. For example, some employers might adopt a policy whereby any individual with a Bradford Factor of more than 500 may need further investigation.
