Training is for the most part free but where a charge is made the Group or District will reimburse you.
Even if your role does not require training you can still choose to do particular modules. To find out out about the module content and requirements visit scouts.org.uk (see links on homepage) and go to members resources.
If you have been helping with a section for quite awhile I strongly recommend that you go to a validation session and discuss what you can be validated for without attending the module course.
You should be allocated a personal training adviser if you have please keep in contact with them and use them to support you in the training.
