Characters

培训 (péixùn) means to train (in a job skill), and doubles as the noun "training" itself: 参加培训 (cānjiā péixùn, attend a training).
Very common in workplace/education contexts: 培训班 (péixùnbān, training class/course), 岗前培训 (pre-job training), 员工培训 (staff training).
Compare with 培养 (péiyǎng) - 培训 is concrete, skill-specific, and often institutional (a course you enroll in), while 培养 is about longer-term nurturing of a person's overall growth or a quality.
Rarely used for raising children the way 培养 is - 培训 is for adult/professional skill instruction.
