There are two methods that the DWP uses to determine whether someone is capable of work

The own occupation test looks at whether the claimant is incapable of "doing work which (he or she) could reasonably be expected to do in the course of his or her occupation." It is usually satisfied by means of the gp's statement and the claimant's statement on the sick note although the DWP may want a second opinion and may ask the claimant to attend a medical examination given by a DWP-approved doctor.

With regard to sick notes, the HMRC (in leafet E14) advises employers to "Remember a doctor's statement is strong evidence of incapacity and should usually be accepted as conclusive unless there is strong evidence to the contrary". The leaflet also lists a number of common diagnoses together with a number of weeks after which an employer may wish to consider seeking further advice.

The personal capacity assessment is applicable after the claimant has been incapable of work for 28 weeks. The claimant will be asked to complete a questionnaire and may also be required to attend a medical examination given by a DWP-approved doctor. The assessment is points-based (you need 15 points to qualify) and covers both physical and mental disabilities. The DWP leaflet on the personal capability assessment states- "Many people on Incapacity Benefits suffer from two or more disabilities. The assessment therefore includes a means of assessing the combined effects of different disabilities, with weighted scores attached to each relevant descriptor."

The are a number of significant exemptions from the personal capacity assessment-
