Should the Management Committee have clarifications regarding your application, it may request a telephone interview and / or request that you attend a relevant training course, to be able to peer review, and validate, your skills and experience.

If you receive clarifications from the Management Committee regarding your application, applicants must respond within 4 weeks from date of the email, or your application will be rejected.

Note there is an obligation on all members to maintain their skills through regular training.  Training can be through formal courses, work experience and/or personal study and it is a requirement of the Code of Conduct.

 If you do not have relevant education qualifications relating to your role, then it is imperative that you demonstrate a comprehensive history of training, and / or continued professional development (CPD).


Please ensure that the description of your main duties highlights your roles and responsibilities within each post you have held as accurately as possible, to provide us with an understanding of your overall career experiences.

Graduate members are required to provide information on any previous paid/voluntary projects relevant to the Association.

If you are applying for membership as a Clerk of Works (CoW):

  • Please clearly highlight the type of CoW role you have delivered, for example, Environmental CoW (EnvCoW), Ecological CoW (EcCoW), Landscape CoW (LCoW), etc.
      • You should be aware how AECoW seeks to define, promote, EnCoW (as outlined on our website here); please demonstrate knowledge, and experience, in accordance with AECoW's definition when completing your application, this will allow the Management Committee to assess your experience, and knowledge, of monitoring compliance, which it believes is central to the role of an EnvCoW and Auditing / Inspecting CoW roles and distinguishes them from other environmental roles.
      • You should be aware how CIEEM seeks to define various ‘EcCoW’ roles. We are working with CIEEM to support each other’s aims and objectives, and to minimise inconsistencies. This includes supporting the development of 'Inspector' and 'Auditing' roles.
  • Please clearly highlight your length / duration / frequency of monitoring compliance experience within your career in relation to the membership grade / criteria you are applying for.

Please provide example projects and a description of your involvement in providing monitoring compliance services, including key decisions made, actions taken and responsibilities. The Management Committee will assess your monitoring compliance experience against the anticipated experience for each membership grade, as well as the quality of your answers in accordance with the following criteria:

  • Full member applicants are required to demonstrate ‘regular’ (eg. weekly) compliance monitoring experience and be either a full, or chartered, member, of another professional organisation (such as CIEEM, IEMA, CIWEM, etc). As a guide, we anticipate that Full Member applicants will have a minimum of approximately four years’ experience.
  • Associate member applicants are required to demonstrate ‘regular’ (eg. weekly) compliance monitoring experience. As a guide, we anticipate that Associate member applicants will have a minimum of approximately two years’ experience.

The Management Committee will assess applications on their individual merit; strong, and experienced, applications which demonstrate a clear understanding, and requirements of the role in accordance with AECoW's definition, may be accepted with a shorter duration. Weaker applications will likely require longer durations and we may request a telephone interview with you.

If you are not able to demonstrate monitoring compliance experience in accordance with the above membership criteria, it may be more appropriate for you to apply as an Affiliate grade.

If you are applying for membership as an CoW:

You need to demonstrate your understanding of the EnvCoW / compliance monitoring role and to explain why you wish to become a member of AECoW. The use of bullet points is acceptable.

Please be concise with your responses and be wary of using words like 'ensure' when describing the role, as EnCoWs are only able offer non site specific advice and direction, and cannot take full responsibility for 'ensuring' works, or compliance.

 As outlined above, you should be aware of AECoW’s position regarding the role of an EnCoW, as outlined on our website on our position statement here.
