A Group Training Organisation (GTO) is a body that employs apprentices and trainees directly, then places them with host employers to carry out their on-the-job training. The GTO remains the legal employer throughout; the host employer provides the work, supervision, and on-site training environment. Builders who want apprentice labour without taking on full employment obligations engage a GTO, pay an hourly rate covering the apprentice’s wages and oncosts plus the GTO’s margin, and carry the supervision duty but not the payroll.

Also known as: Group training company, group training provider.
