English language testing

Confidence in crew communications

Vessels today commonly operate mixed nationality crews: under the IMO STCW Convention, all crew members must be able to communicate effectively in English.

A standardised English language testing procedure for seafarers is therefore a necessary part of recruiting and managing mixed nationality crews on all vessel types.

Flag-recognised English language testing

English language is often a second or third language among seafarers and communication errors are a leading factor in vessel incidents.

We can assist by providing Flag-recognised, consistent, convenient and cost-effective English language testing of your seafarers.

We also recommend standards on English language testing to meet your company’s crewing and training needs.

As the leading provider of Maritime English testing, we can benchmark your results based on international averages to give you and your crew the confidence in their skills.

“Crew of all ranks require an English language level appropriate to their position but this can be overlooked during crews’ career development, from recruitment to promotion in rank.”
