Freelance NVQ Assessors - More Opportunities out there... What are the benfits?

What with the changes to funding and general uncertainty, you may have noticed that more and more organisations are going down the Freelance / Self Employed Assessor route when hiring NVQ Assessors.
Hiring in this way ensures that Training Providers can pay for work done / per portfolio, and they only need to consider if they will require the Assessor short term. Yes there is less stability for NVQ Assessors who go down this route, but if you can get regular work then this can be more lucrative. Plus lets be honest having a 'Permanent' role as an NVQ Assessor is not always as secure as it sounds - If the funding / learners dry up then most organisations have to let their Assessors go!
