A weekly benefit paid to people who are unable to work because of illness or disability, and have paid a specified amount of National Insurance contributions. Paid at 3 rates:
	a short-term lower rate: payable to those who do not qualify for Statutory Sick Pay, for the first 28 weeks of incapacity;
	a short-term higher rate: payable from 28 weeks to 52 weeks of incapacity;
	a long-term rate: payable after 52 of incapacity.
“Incapacity for work” is measured:
	during the first 28 weeks (in the case of people with a recent work record) by the “Own Occupation Test”, which assesses people’s ability to do their usual job;
	after 28 weeks (or from the start of the claim for people without a recent work record), through the “All Work Test”: a functional test which assesses the claimant’s ability to perform a wide range of activities.
Sections 62 and 63 amend the rules for IB; section 61 introduces a modified qualifying test.
