IAESTE internships are among the longest-running and most reliable ways for STEM students to earn real work experience abroad. IAESTE, the International Association for the Exchange of Students for Technical Experience, has been arranging paid technical traineeships since 1948, and today its network spans more than 80 member countries. If you are studying engineering, computer science, mathematics or the natural sciences, an IAESTE placement can give you paid work in a company, university or research institute on the other side of the world.

This guide explains what IAESTE actually does, who can apply, how the exchange model works, and how to move through the application process step by step. The single biggest mistake students make with IAESTE is misunderstanding how the system works, so we will make that clear first.

Key takeaways

What is IAESTE and how does it work?

IAESTE is a non-profit organisation built on a reciprocal exchange model. A company or university in one member country offers a paid traineeship, and an IAESTE national committee in another country sends a qualified student to fill it. In return, the sending country expects to receive interns for its own employers. This give-and-take keeps the system fair and means that even students from countries with fewer local opportunities can access placements elsewhere.

In practice, you do not apply directly to employers for most positions. Instead, your national committee matches your profile to the offers available to your country and nominates you, which is why contacting your local IAESTE committee early is essential.

Who can apply?

IAESTE internships are aimed at students currently enrolled in a bachelor's, master's or PhD programme, and some committees also accept recent graduates, typically within about a year of finishing. The core focus is STEM: engineering, science, mathematics, information technology and related technical fields. Some positions are open to students from other disciplines, but the vast majority are technical.

You do not need to be a citizen of a member country to apply, but you usually apply through the committee in the country where you study, so check how your institution or country is connected to the network.

Are IAESTE internships really paid?

Yes. IAESTE internships are paid, but the important word is sustainable rather than lucrative. Host employers provide a salary or stipend calculated to cover the local cost of living, so the exact amount varies enormously by country and position. A placement in Switzerland will pay far more in absolute terms than one in Brazil, but both are normally enough for a student to live on during the internship.

Housing is typically arranged or subsidised by the receiving committee, and many committees organise welcome activities, trips and a social programme so interns from different countries meet each other. That combination, a living wage, accommodation support and a built-in community, is what makes an IAESTE summer genuinely affordable.

How to apply step by step

The process is slightly different in every country, but it follows the same broad pattern.

Step 1: Find and register

Search open internship offers on the IAESTE website and register on the exchange platform. Once registered, your national committee can see your profile and match you to offers.

Step 2: Contact your national committee

Your committee guides you through the application, tells you which offers are available to your country, and helps you prepare the required documents, typically a cover letter, CV, transcripts and sometimes language certificates.

Step 3: Get nominated and accepted

If the committee selects you for an offer, your documents are forwarded to the employer, who makes the final decision. Once accepted, you receive details about your start date, insurance and accommodation, and the committee helps with visa paperwork where needed.

What documents do you need?

Prepare a strong cover letter and an up-to-date CV that highlights relevant coursework, projects and technical skills. Many committees also ask for academic transcripts and evidence of English proficiency, since English is the working language for most positions even when the host country speaks another language. If you are unsure how to structure a persuasive motivation letter, our guide to writing a winning statement of purpose covers techniques that apply here too.

Visas and insurance

Because you travel as a trainee rather than a student, visa rules differ from country to country. Some placements are short enough to fall under a visitor visa, while longer internships require a specific work or training visa. The receiving IAESTE committee coordinates most of this, but start early and keep copies of every document. For a general overview of what the process involves, see our student visa guide.

Making the most of your placement

An IAESTE internship is as much about the experience as the salary. Interns come away with real technical experience, an international network and a CV that stands out to graduate programmes and employers. Take part in the social programme, keep a record of the projects you work on, and ask your supervisor for feedback and a reference at the end.

How to apply: next steps

Start by finding the IAESTE office for your country on iaeste.org and asking how the local cycle works, because committees often have their own application windows and deadlines. Prepare your documents, register on the platform, and check the open internships regularly so you can signal interest in the offers that fit you best.

Then treat your IAESTE application with the same seriousness as a job interview, because that is effectively what it is. For more funded international work experience ideas, browse our internships hub and our playbook for funded summer research internships abroad.
