26.1 In the codes of practice, for most jobs, there are two different minimum salary rates. One is for ‘new entrants’ the other for ‘experienced’ staff. These rates have been set to make sure that the resident labour market is not undercut. The rates of pay are up-to-date and in line with current earnings of settled workers. These rates are updated every April.
26.2 The new entrant rate reflects the fact that people in the early stages of their career are generally paid less than their more experienced counterparts. The new entrant rate can be paid if you have met the resident labour market test by carrying out a milkround, or the migrant is switching into Tier 2 (General) and was last granted leave to enter, or stay in the UK under:
a) Tier 1 (Post-study work), or
b) Tier 1 (Graduate Entrepreneur), or
c) the International Graduates Scheme, or
d) the Fresh Talent Working in Scotland Scheme, or
e) the Science and Engineering Graduates Scheme, or
f) Tier 4 or as a student and they have received final results confirming that they have passed and will be (or have been) awarded:
a UK recognised bachelor’s or master’s degree, or
a UK Postgraduate Certificate in Education, or
a Professional Graduate Diploma of Education, or
they have finished a minimum of 12 months study in the UK towards a UK PhD.
26.3 The new entrant rate can also be paid if the migrant:
a) will be sponsored under the Tier 2 (ICT – Graduate Trainee) category, or
b) is under the age of 26 on the date of their application for Tier 2.

You meet the definition of “new entrant” if you fall within one of the following categories:
you are under 26 years old on the date when you make your Tier 2 immigration application
your Tier 2 sponsor recruited you by carrying out a university milkround (check with your employer if that applies to you)
you meet the requirements of the post-study work exemption from the resident labour market test.
