Depending on the duties you expect your PAs to perform you will probably need to provide at least some training to your staff. In some cases this may be optional, but for many duties (like Moving and Handling or Administering Medication) it is legally required.
If you don’t provide your PA with training that is legally required and an incident occurs due to a lack of training then you may be liable.
Sadly, SPAEN doesn’t offer training courses ourselves. It is best to check if there are any training courses in your local area/areas PAs can get to. The Scottish Social Services Council offers a free Learning Zone with resources that you may find useful, no fee or login required.
