May it be corporate offices, Government offices and charitable organizations; training is needed at various stages of job from executives to administrators, from teachers to principals, from line officer to JE and from nurses to Doctors etc. For this purpose, various innovative methods and procedures have been used from time to time. Simulation is also one of such kind of technique which is gaining its momentum worldwide these days. Though simulation has its history way back to the period of World War II when two mathematicians Jon Von Neumann and Stanislaw Ulam used it to solve the puzzling problem of behavior of neutrons, its importance in the field of Teacher training has been recognized more only after NCFTE,2005 and 2009. This paper hence deals with the use of simulation models in Teacher Education for Teacher training and also throws light on its future prospects.
