Cambridge English for Engineering

Cambridge English for Engineering develops the communication skills and
specialist English language knowledge of engineering professionals,
enabling them to communicate more confidently and effectively with
colleagues and customers.
The ten standalone units cover topics common to all kinds of engineering
(including civil, electrical and mechanical) such as procedures and
precautions; monitoring and control; and engineering design. Authentic
activities, from describing technical problems and suggesting solutions
to working with drawings, make the course relevant and motivating.
The course requires no specialist knowledge on the part of the teacher
and comprehensive teacher's notes are available online. It is also ideal
for self-study.
