Who are the "we" you are referring to?
FIC Instructors was the aim of the question.
If an organisation provides training for the Instructor Rating and the requirements for starting the course are x then provided that the candidate meets the minimum requirements you are not permitted to block their attempts to complete the course by adding higher personal requirements.
We can discuss the merits of the system all day long, but there is an opinion on this forum that newly minted intergrated graduates or people who want to undertake the FI course meeting the minimum requirements of the authority wont be 'experienced' enough to make a good instructor.
I have my own opinion about that.
So, my question was directed at those who feel the minimum is not enough - how do they apply their 'higher' standards?
