Each trainee only spends the time required to gain the still missing knowledge.

Besides attending regular classes, trainees spend many hours a day learning music, choreography and sometimes foreign languages including Japanese and English, because K-pop music is often produced for overseas export.

The trainees had spent a month practicing with various configurations of attack craft, dropping bombs in the isolated red deserts, shooting at gigantic targets painted on the mile-high canyon walls.

We're reforming teacher training so that trainees spend more time in the classroom.

The trainees spend so much time in the field, they say they hardly feel human.

Work placement is an important feature of our programmes, with trainees spending three days a week in a variety of settings, including homes for the elderly and day care centres.

Within two or three years, all post-graduate trainees will be spending 80 per cent of their time in schools learning on the job instead of listening to lectures on education theory.

At Duke, for instance, trainees spend four years in training before taking a licensing exam.

Each trainee will spend six months in training; classes of 330 people will enter each month until a force of about 6,000 is functioning.

Even once training is completed, trainees will spend an apprenticeship period working on varying projects before becoming full-fledged katsas.
