International internships can help students gain practical experience, strengthen their CVs and build professional networks beyond their home country. However, one common concern for international applicants is whether an IELTS or another English-language test is compulsory.

The good news is that several well-known international organisations and research institutions offer internship programmes where IELTS is not specifically listed as a compulsory application requirement.

Below are five international internship opportunities in Japan, Switzerland and France worth exploring.

Note: “Without IELTS” does not mean that English-language ability is unnecessary. Some programmes require applicants to have a good command of English or another working language even when an IELTS certificate itself is not required.

The Okinawa Institute of Science and Technology (OIST) Research Internship Programme gives undergraduate and Master’s students, as well as eligible recent graduates, an opportunity to gain hands-on research experience in Japan.

5. OECD Internship Programme – France

The Organisation for Economic Co-operation and Development (OECD) Internship Programme offers university students the opportunity to work alongside policy experts and specialists in an international environment.

Unlike programmes with only one annual deadline, the OECD recruits interns on a rolling basis throughout the year.

What Does “Without IELTS” Actually Mean?

This distinction is important.

An internship described as “without IELTS” usually means that the programme does not specifically require applicants to submit an IELTS certificate as part of the application.

It does not necessarily mean there are no English-language requirements.

For example:

• OIST: IELTS/TOEFL scores are optional for the Research Internship.
• CERN: Applicants need appropriate working knowledge of English or French.
• OECD: Applicants are expected to have excellent command of English or French.
• WTO: Applicants should check the specific programme requirements and working-language expectations.

Therefore, applicants should always distinguish between “IELTS not required” and “no language requirement.”

How to Choose the Right Internship

Do not apply based only on the fact that IELTS is not required. Your academic background and student status are usually much more important.

Science and research students may find OIST particularly relevant, while engineering, computing and technical students may want to explore CERN.

Students interested in economics, international relations, law and global trade may find the WTO opportunity more closely aligned with their academic background.

The OECD Internship Programme covers a particularly broad range of policy, research, technology, communications and administrative disciplines.

Before applying, compare the programme requirements with your:

• Academic level

• Field of study

• Nationality

• Current student status

• Graduation date

• Relevant skills

• Internship availability

• Language proficiency

Final Thoughts

An international internship can be an excellent way to gain practical experience, develop professional skills and understand how internationally recognised institutions operate.

The absence of a compulsory IELTS certificate can also make some opportunities more accessible, particularly for students who can demonstrate their language skills through their academic background or practical communication ability.

However, every programme has its own eligibility rules. Requirements relating to nationality, student status, academic discipline and language ability can change between application cycles.

Always review the official programme website before preparing or submitting an application.

Mindship Global Tip:

Do not search only for internships labelled “No IELTS.” First find opportunities that match your academic field and level, then check whether the programme actually requires an English test certificate. Many international internships assess language ability without making IELTS compulsory.
