On-the-Job Training (OJT): On-the-job training is convenient and inexpensive. It provides first-hand job knowledge and experience under actual . working conditions. However, the noise of the workplace may distract the attention of trainees and they may find it difficult to concentrate on learning. Two methods for on-the-job training are given below: 

1. Job Instruction Training (JIT): This is the most popular form of on-the-job training. It is also known as step-by-step training. 

It consists of the following steps: 

• Preparing the trainees by telling them about the job and overcoming their initial nervousness; 

• Presenting the instructions, giving the necessary information, interacting, illustrating and asking questions; 

• Letting the trainees try out the job or show their understanding; 

• Observing, try out and providing necessary assistance and follow-up. 

2. Apprenticeship Training: Under this method, the trainees learn by r working with those who are already skilled in their jobs. People who want to enter skilled trades (such as welder, plumber, electrician, machinist) are required to undergo apprenticeship training. In an apprenticeship programme, classroom training is given first and then the trainees try out the job under the guidance of a master worker. Classroom training focuses on theory and auxiliary skills. In job try-out the trainees gradually learn the skilled craft. An apprenticeship programme may run from 2 to 5 years.
