There are some other training approaches and models. As it has been discussed earlier that training evaluation itself is less touched part of training and development, these methods have theoretical side but less in practical application. So these models are not discussed in detail. These are: Training Validation System (TVS) approach (Fitz-Enz, 1994), Input, Process, Output/ Outcome (IPO) Model (Bushnell, 1990), Hassett‟s training investment analysis approach; Kaufman‟s five level evaluation model, Mahapatra and Lai (2005) and Sadri and Synder (1995).
