IAM Endorsed Assessors Scheme

The IAM’s Endorsed Assessment (EA) scheme provides access to suitable, reputable assessment providers that can deliver relevant, high quality asset management assessments of organisations using knowledgeable assessors.

The IAM believes that organisations will realise business benefits from their assets by developing and implementing asset management practices, and that the best way to achieve this is for organisations to develop asset management systems that conform to the requirements of ISO 55001 or BSI PAS 55.

IAM Endorsed Assessors assess organisations’ management systems against ISO 55001 or BSI PAS 55. EAs assess the extent of conformance to these requirements through gap analysis to understand what needs to be done for the management system to conform. If desired, when organisations are considered to conform to the requirements, assessors can issue a certificate. For further clarification on conformity assessment, accreditation and certification, please consult the IAM Endorsed Assessor Scheme FAQs.

What are the benefits of using an IAM Endorsed Assessor?

Although organisations can implement AM systems by themselves, there are benefits in using an independent third party to assess conformance. Anybody can declare themselves to be a Certification Body and issue a certificate of conformity for an ISO management system standard or specification. The IAM set up its Endorsed Assessor scheme so that organisations and their stakeholders can have confidence in the competence and capability of assessment and certification services.

Even though National Accreditation Bodies are establishing ISO 55001 accreditation schemes, the IAM will continue the EA scheme, as these accreditation schemes are only designed for Certification Bodies and not for assessors that only wish to offer assessment for gap analysis. The IAM believes that assessors undertaking gap analysis should have the same competence in asset management and auditing as those involved in certification assessments. The IAM’s EA scheme provides this assurance.

(If your organisation would prefer certification against ISO 55001 to be undertaken by an Accredited Certification Body, you should be able to source these via National Accreditation Bodies, such UKAS for the United Kingdom.)


Apply to become an IAM Endorsed Assessor

EAs can be endorsed for assessing conformity to ISO 55001 and/or PAS 55 for gap analysis and/or certification. The IAM assesses applicants against the requirements of the EA scheme and, if successful, appoints them to the status of Endorsed Assessor for a period of three years (renewable).

It is important that you understand the requirements of the scheme before you submit your application. As well as completing the application form, please ensure you have read the other documents available. These documents identify the evidence and assurances the IAM will require you to provide if your application is to be successful. The application process usually takes 1-2 months, depending on the provision of documents required and the availability of application reviewers.

All EAs are required to be members of the IAM.
