According to a study by Diamantidis and Chatzoglou, (2012), there are four important competencies that have been noted within a trainer. These competencies are mainly categorised as motivation, reinforcement, retention and transference. The need for motivation is crucial so that there can be needs generated within the employees of the organisation to learn new skills and abilities which could ultimately allow them in performing their roles and responsibilities with higher effectiveness levels. Apart from this, the competency of reinforcement is crucial in encouraging correct modes of behaviour within the trainees. The retention ability allows the trainers in demonstrating correct performance by practice whereas the ability of transference allows the trainers in providing original learning opportunities that are faced by employees when working practically on their roles.
According to Ricks, Williams and Weeks (2008), a HR trainer is required to possess large number of competencies in order to impart better quality of learning and development within the employees. One such significant trainer’s competency is that of facilitation. This facilitation competency of the trainer allows them in leading group discussion without directing the outcome and also enables them in creating an environment of trust and openness. Apart from this, good communication is also regarded as an important competency that allows trainers in performing their role of training to employees in a positive way within organisation. Trainers must be able to speak fluently because they are required to address large number of people and have to express themselves, and convey their ideas in a manner that is quite easy for the learner to understand. These important competencies are identified as crucial by Ricks, Williams and Weeks (2009) and they must be possessed by a trainer in order to facilitate a better platform of learning.
