From 4 July 2011, you cannot bring your dependants to the UK unless you are:

• sponsored by a higher education institution on a course at NQF level 7 or above which lasts 12 months or more; or
  a new government-sponsored student following a course which lasts longer than 6 months.

If your dependants are already in the UK with permission, they will be allowed to extend their stay provided they apply at the same time as you apply to undertake a course of study lasting more than 6 months.

Dependants must apply under the rules for points-based system dependants. You can download guidance from the right side of this page.

it doesn't have to be level 7 to keep dependents in the UK, it depends on the main applicant and what he/she has done in the past.
