Membership FAQs

When non-members were polled in 2024 about 'what would be their main reason for joining CIOL?' two benefits emerged as clearly the most popular:

• Professional status and recognition as a linguist
• Improved work and career prospects

Other important benefits were:

• Opportunities to network with other language practitioners
• Keeping in touch with what’s going on within the languages profession
• CPD and other professional support
• Belonging to a vibrant professional community of linguists
• Commitment to professional integrity through the code of professional conduct

Our affiliate grades are for linguists studying either an academic, vocational or professional language qualification, for linguists who are just starting their career and for practitioners who use languages in the course of their work but where languages are not the main component of their job. The CIOL affiliate grades are Career Affiliate, Study Affiliate, Student Affiliate and Affiliate Linguist.

There are three grades of professional membership: Associate (ACIL), full Member (MCIL) and Fellow (FCIL). Professional membership of CIOL demonstrates that you have met the rigorous requirements and standards for good practice in the professional use of your language skills. Membership is open to anyone who uses their foreign language skills in a professional context, whether employed or freelance. This includes interpreters, translators, and foreign language teachers, and lecturers, providers of specialist language services and linguists who work in business, commerce and industry. Find your grade.

Membership of CIOL offers practising and aspiring language professionals and linguists a range of benefits and services which will enable you to be recognised, raise your profile, support your professional development, provide access to valuable information and tools and connect you with other linguists through our member networks.

As a professional member, you will be able to use the designatory letters "ACIL" (Associate), "MCIL" (Member) or "FCIL" (Fellow), plus "CL" for members who are chartered.

Professional membership inspires trust and confidence in clients, employers and peers and the designatory letters are a public demonstration that you meet CIOL's rigorous criteria and standards for best practice in the use of languages professionally. 

Affiliate membership (Career, Study, Student and Affiliate Linguist) illustrates your commitment to your languages as well as your support for the study of languages, professional standards and the values of chartership.

The full range of benefits for each grade of membership can be found here.

You are more than likely eligible to apply for chartership if you:

• meet the eligibility criteria to be admitted as a full Member (MCIL) or Fellow (FCIL),
• are in current professional practice and have been for at least five years, and
• can demonstrate a commitment to Continuing Professional Development 

You can apply online. Please first ensure you have read the membership entry criteria in full and have gathered the evidence you need to support your application.

All Affiliate, Associate, Member and Fellow applications must be accompanied by a one-off non-refundable £30 assessment fee. There is no assessment fee required for Student Affiliate or Study Affiliate applications.

The full membership fees are detailed here.
