Quick guides to apprenticeships
The academic provider that provides the academic learning (university or college)
The employer who provides the work based training
And the apprenticeship provider who oversees the apprenticeship framework.
Typically the apprenticeship employer works through the apprenticeship provider in sourcing suitable applicants. The academic side is typically arranged by the provider with approval from the employer.
Positions are usually posted by the provider and/or employer online, not on the university websites.
Hope this helps.
