Certified Pro Network

I was admitted into the Certified PRO Network in 2015 after a sample translation from French into Danish was approved. Three years later, a sample translation from Danish into UK English was approved. Only two combinations can be approved. As I ceased to be a paying member in 2023, the Certified PRO status was discontinued.

You can find a description of the Certified PRO Network here (external site, opens in new tab).

Evaluation of test translation from Danish to UK English

Test submitted in August 2016 to a major international travel booking site

The test was evaluated anonymously by the end client. The full test evaluation is reproduced below with permission from the translation agency - Translations, S.L.


Overall, the content and meaning are transferred correctly from source to target. There were no omissions or alterations in meaning.

Style and idiomatic language

The translation presents good, idiomatic English and an informal style and tone appropriate to the context.

The translation is of high stylistic quality, does not contain any "Danglish," and flows very well.

The translator used specific, descriptive adjectives instead of clichés.


The source does not contain any difficult terminology. The translation does not contain any terminology errors. This translator was the only one of the group who used the term "concrete stelae" to describe the pillars of a famous monument, which shows great attention to detail.

Spelling and grammar

The translation does not contain any spelling errors or grammatical errors at all.


Overall, this translation is of very high quality. The translation reads like a text originally written in the target language. It accurately accomplishes the goals and function of the original; only a few minor stylistic changes might be made by a proofreader. The text follows the principles of good writing in English: the correct tone of voice is used for this content type; active verbs are preferred over passive; specific, evocative adjectives are used instead of clichés; the reader is addressed appropriately; and the text "flows." Amazing job.

You write with fluency and eloquence even if the topic is mundane. Frankly, I love to read anything you write.”

“Thomas T. Frost has an amazing ability and facility for languages. I have corresponded with him, and had him work on my websites in English here in the United States.”

“Thomas has corrected several of my faux pas in English. And I am a native speaker. He is a stickler for correct grammar. He's also good at finding better ways of saying what you want to communicate. His English and French communication skills are at the very highest level. He really enjoys being very precise with language.”

“I'm extremely pleased with the presentation work that Thomas has done on my websites.”

“Mr. Frost has also helped me with business communications in French, for which I was extremely pleased.”
