Identifying Internal Trainers

Hi!
Can somebody share an effective format for identifying internal trainers in an organisation??
so that we can save on cost for external trainings!!

Dear
Only way is to conduct Train The Trainer program
for identifying the potentials of your people as Trainers

Sir, i am into manufacturing unit and people out here are not that receptive to tarinings and all.. they feel its a wastage of time, we did conduct a program on " Train the Trainer" but people were not intersted to join that program... so i was just looking for a format wherein we can distribute it to potential people and on the basis of that we can judge that who can be a good potential internal trainer...
i have made this format but not sure how effective it can be!!!
