I did some work for a well-known organisation recently. My job was to investigate ESP teaching in universities in the capital city and make recommendations. I spent a few days driving round the city, meeting teachers, lecturers, administrators, course directors, students, subject lecturers etc. and was generally very impressed. The ESP teachers knew what they were doing. They had talked to students, lecturers and course managers. They had examined students materials. They knew what the students had to read and to write and had analysed the required language and designed their courses accordingly. The only problem I could see was that the various universities did not talk to each other and so the main recommendation I made was that there should be ways in which the universities could talk to each other and share materials and ideas.Wrong Recommendation!
I did not hear much from the organisation that employed me, but I heard later that I was supposed to have recommended training, especially of the CELTA type!
