Professional guidance for interpreters working through Tolk2Go



Professional Standards for Interpreters

Interpreters have an important responsibility in helping people communicate across languages and cultures. The work requires preparation, professional judgment, accuracy, confidentiality and respect for everyone involved.

The guidance on this page is based on general principles described in ISO 18841:2018 , “Interpreting services — General requirements and recommendations”.

These are professional principles, not a replacement for the ISO standard. Interpreters must also follow the laws, professional codes, contractual terms and specialist requirements that apply to their country and assignment.

Ten Core Responsibilities

1. Accept Suitable Assignments

Accept assignments only when your language skills, qualifications and experience match the requirements. Check that the working conditions and agreed terms allow you to deliver the service properly.

2. Request Necessary Information

Make sure you receive the relevant date, time, location, subject, participants, background materials and technical requirements before the assignment.

3. Maintain Professionalism

Be punctual, prepared and appropriately dressed. Introduce yourself, explain your role and follow the relevant professional protocols.

4. Interpret Accurately and Impartially

Communicate the message faithfully without adding, omitting or changing content. Use direct speech where appropriate and help keep the conversation clear.

5. Follow Codes of Conduct

Follow applicable ethical guidelines, professional codes, assignment protocols and standards of practice.

6. Maintain Confidentiality

Keep the content of assignments confidential, especially when interpreting sensitive, personal, medical, legal or business information.

7. Report Problems Promptly

Report technical difficulties, safety concerns, conflicts of interest, unclear instructions or other issues that may affect the quality of the service.

8. Ensure Suitable Working Conditions

Check that the environment, equipment, seating, sound and visibility are appropriate for the assignment. Raise concerns when adjustments are needed.

9. Protect Your Well-being

Manage your workload and breaks to reduce fatigue, burnout and secondary stress, especially during demanding assignments.

10. Debrief When Appropriate

Where suitable, participate in a debriefing after the assignment to discuss challenges, improve future service delivery and identify professional development needs.


Before Accepting an Assignment

  1. Confirm that the language combination matches your skills.
  2. Check the subject, sector and level of specialization required.
  3. Review the date, time, location, duration and working format.
  4. Request documents, terminology or background information needed for preparation.
  5. Confirm the agreed rates, travel arrangements and assignment conditions.
It is professional to decline an unsuitable assignment. Accepting only work that matches your qualifications protects you, your client and the quality of the interpreting service.

During the Assignment

  • Arrive or connect on time and be properly prepared.
  • Introduce yourself and explain your role to the participants.
  • Interpret the complete message without personal additions or omissions.

  • Protect confidential information and avoid discussing the assignment with unauthorized people.
  • Report technical, safety or communication problems promptly.
  • Take appropriate breaks during demanding or extended assignments.

After the Assignment

After completing an assignment, check whether any follow-up is needed. This may include returning materials, confirming administrative details or participating in a debriefing.

A short debrief can help identify practical improvements, clarify any difficulties and support continued professional development.

Review What Happened

Consider what worked well and whether any communication or technical issues occurred.

Report Relevant Issues

Inform the appropriate person or organization about problems that may affect future assignments.
