Blended courses are basically reducing the face to face time with the instructor , which makes it safer from a covid 19 point of view. For the blended course the student does the theory bit online and then just the practical element with the instructor
By doing the "Blended" courses , the student spends less time away from work with the instructor doing the face to face practical element. The theory part is done online , in your own time and at your own pace.
The "Blended" courses are recognised at level 3 by HSE, OFSTED and CQC.
