Application procedure

Application to the Institution of Environmental Science is carried out through a paper-based review process. Applications are assessed by a membership panel which convenes approximately once a month, and is made up of IES Council members.

One application form covers Full and Associate Membership. There are separate forms for Fellowship, Students and Affiliate applications. Please download the relevant form, and read though it carefully, before sending it to the Institution.

Applications to the IES are graded on a points system, with the total made up from a combination of academic and work experience. The final decision on the appropriate membership grade will be with the Application Review Panel (ARP).

Academic experience criteria

Qualification Relevant Non- relevant
Relevant PhD 8 4
Relevant Masters 7 3.5
Relevant Bachelors (Hons) 6 3
Relevant Bachelors 5 2.5
Relevant HND/ Foundation Degree 4 2
Relevant HNC 2 1

PgDips and PgCerts will be judged on a case-by-case basis by the ARP.

Judged on the highest qualification e.g. PhD 'trumps' a Masters degree. The IES uses the ES3 Benchmark Statement from the Quality Assurance Agency (QAA) to judge the relevance of degrees. International qualifications should be translated into their UK equivalents. There are some additional degrees not mentioned on this list that will be considered relevant at the ARP's discretion. International qualifications should be translated into their UK equivalents.

Work experience criteria

The IES focusses importance on professional experience and development. Years (and therefore points) accrued whilst in relevant employment signals experience, commitment and achievement in the environmental science sector. Applicants therefore must demonstrate how their work is aligned to the sector.

  • ½ unit for every six months relevant work experience at graduate level.
  • Relevant university placements may count towards your work experience.
  • The ARP can award points for partial relevance, e.g. a Health and Safety & Environmental Officer may be awarded 1 point for every 3 years work.
