some advice please having spent time on the SIA site and not really finding an answer,
Are the SIA required courses and qualifications hierarchical ?
if I do the CPO course can I apply for event security work/static guard work etc.
If you have a CP licence you can legally do work needing an SG or DS licence. That will include event work. However, some employers will still want you to do a relevant course, more usually for retail security. For some event work (particularly sports stadiums) you might need the NVQ in Crowd Control but you usually do that whilst working and wouldn't need it to get a job.
