Diploma in Translation – CIOL DipTrans Exam Guide 2025

Why do the CIOL DipTrans exam in 2025 if you want to become a translator? Because accredited translators get more work.

The Diploma in Translation (DipTrans exam) is a postgraduate-level translation qualification awarded by the Chartered Institute of Linguists (CIOL).

The DipTrans will help you improve your career prospects. It’s an alternative to a translation degree that can contribute to you getting better-paid work as a professional translator. This article will tell you everything you need to know about the DipTrans qualification.

If you’re starting out as a translator, you should do the CIOL CertTrans exam first.

What’s the Diploma in Translation (DipTrans)?

The Diploma in Translation, known as the DipTrans, is the postgraduate level professional qualification issued by the renowned Chartered Institute of Linguists (CIOL). It’s the translation qualification to get if you’re working as a translator or thinking of becoming one.

Set at Ofqual Level 7 (master’s level), you get it by sitting a translation exam. The qualification is internationally recognised and accepted by the translation industry. Once you’ve passed, you can add the letters CIOL DipTrans after your name.

The CIOL says: “the Diploma in Translation (DipTrans) is the gold standard for anyone wanting a career as a freelance translator or to work as a translator for international corporations worldwide and meets the need for a high-level professional translating qualification.”

What languages can you sit the DipTrans in?

You can sit the DipTrans from the following languages into English: Spanish, French, German, Italian and Russian.

If you translate from English, you can sit the DipTrans going into a long list of target languages: Albanian, Arabic, Bengali, Chinese, Croatian, Czech, Danish, Dutch, Finnish, French, German, Greek, Hindi, Hungarian, Italian, Japanese, Norwegian, Panjabi, Polish, Portuguese, Romanian, Russian, Slovak, Spanish, Swedish, Tamil, Turkish and Urdu.

How long is the CIOL DipTrans exam?

The DipTrans consists of three separate exams that take a total of seven hours to sit. In each exam (called units), you have to produce a written translation of a source language text. The exam texts have a combined wordcount of about 1,500 words.

What are the papers in the exam?

Unit 1 is a general translation of about 600 words. You have three hours to translate it. The content could be a newspaper article or another similar type of journalistic text.

Unit 2 is a semi-specialised text of about 450 words, and you can choose from technology, business or literature. You have two hours to complete this part of the exam.

Unit 3 is also a semi-specialised translation, and the options are science, social science or law. Like in unit 2, it’s around 450 words and you have two hours to complete.

You can sit all three units or just one or two. But to gain the qualification, you must pass all three papers within three years. This is new from 2021, before this year, candidates had five years to pass all papers.

Is the DipTrans an exam or a course?

The DipTrans is an exam that you must prepare for. The Chartered Institute of Linguists (CIOL) says candidates must be competent in both the source and target languages, have good writing skills and the ability to translate at a professional level.

According to the CIOL: “it must be stressed that candidates, even those holding a degree in languages, generally require additional experience or training.” Most translators take a course to prepare, even very experienced ones. The Translator’s Studio offers a pre-DipTrans and DipTrans course with plenty of course content and translation assignments to help translators get ready to sit the Diploma in Translation exam.

What’s the difference between the DipTrans and an MA in Translation Studies?

The CIOL Diploma in Translation is a master’s level 7 qualification, but it isn’t a course.

Both the DipTrans and an MA are post-graduate level 7 qualifications. However, an MA (Master of Arts) is a course taught by a university that you complete over one or two years. You have to attend lectures and do assignments, as well as a lot of reading and studying. If you complete the work to the appropriate standard, the university awards your MA.

A master’s degree (MA or MSc) isn’t the same as the unofficial and unregulated “master’s” certificates you can get through courses offered by centres in certain European countries like Spain.

The CIOL DipTrans examination also leads to a post-graduate level 7 qualification but it’s an exam, not a course. Unlike an MA, where you learn to translate and if you reach the required standard are awarded the qualification, you must already have the required level when you sit the DipTrans exam. There’s no teaching involved. It’s simply a test of your professional translation skills on the day.

You need extensive knowledge of translation to pass. Most translators do a preparatory course and try to get some professional translation experience before they sit the DipTrans. At the Translators Studio, we have outstanding translator trainers. We can prepare you for the exam and help guide you on getting some experience. Get your free level test.

Candidates should read the exam specification and do a course if they can possibly afford it.” Watch the full interview on how to pass the DipTrans.

Read more about how accredited translators get more work.

Is it better to have the DipTrans or an MA?

Although they are both post-graduate level 7 qualifications, the DipTrans and an MA are very different. An MA is a course of study and the DipTrans is an exam. The two qualifications share some common challenges but they’re very different. One key difference is that the financial investment is much higher for a university MA in translation studies. Check out this article for the lowdown on the differences between the two.

Can I sit the CIOL DipTrans exam if I don’t have a language degree?

Anyone can contact the Chartered Institute of Linguists and sign up to sit the Diploma in Translation exam. But the CIOL warns that even translators with a degree in languages “generally require additional experience or training”. Because it’s such a challenging exam, The Translator’s Studio has developed a set of pre-DipTrans and DipTrans preparatory courses to get you ready to sit the exam. If you’re not aiming for the qualification just yet, but want to get started in translation, check out our Conversion Course.

Yes. In emails exchanged with the CIOL, we’ve confirmed that you can examine into US English. This means the DipTrans exam is suitable for translators in the USA, Canada, Latin America, Australia and anywhere else in the world.

Our DipTrans preparatory courses are suitable for translators based in the USA, Canada and Latin America. We have many students from the Americas who take our courses to prepare for the DipTrans, the ATA exam or for professional development.

What’s the difference between the DipTrans and the ATA certification exam?

The American Translators’ Association (ATA) certification exam leads to a certificate issued by that professional translators’ association. It’s a three-hour invigilated exam that consists of three passages with a combined total of about 750 words.

Translators can use paper resources and have limited access to the Internet. It’s designed to test the translator’s ability to produce a professional translation. The pass rate at time of writing is less than 20%.

The Translator’s Studio courses can help you acquire the skills you need to pass this exam. Check out this interview between Gwenydd Jones and the ATA head of certification David Stephenson.

What’s the difference between the DipTrans and the ITI membership exam?

The Institute of Translating and Interpreting (ITI) membership exam is one route to joining that professional translators’ association. The ITI exam is a 1,000-word translation that you can produce in your own time over a weekend with full access to the Internet and to consultation with other translators. It isn’t a qualification and the only assurance that the translation is the translator’s own work is a signed declaration by them.

The DipTrans is a post-graduate level 7 qualification obtained in an invigilated exam without access to the Internet. It’s equivalent in level to an MA in translation and accredited by Ofqual. It’s the industry gold standard and it proves that you can translate professionally under strict exam conditions.
