ISO27001 Lead Implementer Training

1 - I recognize that the exam for the course provided by Advisera is "accredited" by Exemplar Global but there seem to be several ISO27001 Lead Implementer qualifications provided by and accredited by various companies. Are these qualifications benchmarked against each other to ensure they are the same level of detail/difficulty?  

Unfortunately, at this moment our ISO 27001 Lead Implementer exam is not accredited, but we are in the accreditation process at this moment. As soon as this process is concluded our customers will be contacted.

Considering accredited exams, you need to check if the accredited providers are certified against ISO 17024 – which provides general requirements for bodies operating certification of persons.

Provided they fulfill this standard’s requirements, their certifications qualification levels are similar.

These articles will provide you a further explanation about ISO 27001 personnel certifications:

2 - Also, having passed the exam can you state you are an "ISO27001 Lead Implementer" or do you need to demonstrate some level of practice in the industry (in the same way as the CISSP and CISM qualifications) to an overarching body?

I’m assuming that by overarching body you mean “certification body”, or a similar organization that is responsible for issuing the certification (like ISC2 for CISSP and ISACA for CISM). 

Considering that, depending on the organization that is responsible for the exam, there may be other requirements to fulfill to be allowed to use the title "ISO27001 Lead Implementer". To know the specific detail you need to contact directly the exam provider.

For Advisera's ISO 27001 Lead Implementer Course, there are no additional requirements but attending the workshop and passing the exam.
