When human resources managers plan business English classes it’s a good idea to pay extra attention to something that’s often forgotten: the length of each lessons.

 

Short classes are easier to fit in busy schedules—but sometimes don’t allow the teacher to work on complex subjects. Long classes let us study matters more deeply. However, they require concentration over prolonged periods. 

 

In my experience, traditional in-person business English lessons should last between one and two hours. The exception? Business English intensive courses, where learning is based on immersion and lessons need to be packed after one another.

 

Online lessons, on the other hand, can be as short as twenty minutes but should not exceed sixty. The main challenge with online lessons is maintaining student attention. Regardless of teacher engagement or interest, students often struggle to remain focused for a long time when classes are via a screen.

 

In summary, I recommend durations ranging from 60 to 120 minutes for in-person classes and 20 to 60 minutes for online sessions.
