So, I was reading the radical's handbook and came across the bit about psychic adepts, wherein three suggested options are laid out (become a sorcerer or nascent psyker, or get sanctioned).

After doing some digging on the forums, I managed to find some info about the so-called 'field sanctioning' (or at least I think I did), in the form of the 'The Mind's Eye Opens' transition package from Ascension.

I'm sort of left wondering though, and maybe this has already been addressed somewhere that I haven't noticed, is there any suggestion as to how something like that should be handled mid-campaign in a game that isn't mid-transition to Ascension/doesn't span years of time?

Is it really reasonable to expect a player to sit out (depending on whether you go by the DH Sanctioning description or the Ascension package noted above) between 1d5 to 3d10 years of game time to become a bottom-rung psyker that isn't 100%-HERESY and/or so random as to be of questionable value? From a fluff perspective, I could see that; but from a is-this-fun-for-the-player, it almost begs the question 'why bother?'.

I've also seen note in some threads about the Inquisition - and I'd assume possibly other organizations associated with replacement ranks that offer a psy-rating advance - having the right to determine what psykers need sanctioning (which sort of makes sense given the nature of the Inquisition), but I was wondering what form such powers would take (would it 'force' the nascent psyker package?).

Obviously, a lot of that would be up to the GM as to the final say, but I'd to hear some thoughts from folks with more experience with the game and setting.

The question also goes for the Adept, how can he choose the career path with psyker abilities, since he did not have them in the first place? Did he get sanctioned earlier in life because he was expected to develop psyker abilities?

In my campaign I had an Adept going psyker, and I went with the Inquisition pulling some strings to get him "field" sanctioned at Scintilla. This happened after being examined for a few months in a black ship en route to Scintilla by an Inquisitor, which was actually fun to role play. Of course he did not get the chance to get tested at Terra and have thus not met the Emperor.

In game terms I would think an adept who is nascent or just beginning to learn of his psyhic abilities has the possibility of developing the in game random 1d5-3d10 just as easily it would to try and decsribe in game narrative time or a narrative backround package that the adept already has developed. Look how long it takes a Sanctioned Psyker to foster his psychic manifestations IC. Before the character is made and fleshed out there is already the idea that he has been born with psychic abilities but with an Adept I would forsee an Adept who has delved into forbidden daemonology, warp, or some sort of Ruinous Power manifestation from corruption or malediction that could bestowe his/her psychic manifestations easily and fast. Remember what an Adept is....He is somebody who collects lore, information and basically writes down the information. Im sorry I dont have my books to help research the information but what Im trying to say that using Narrative Time is justified its just how you play it out in the game. If it is a nascent adept, then anytime would justify his advances, skills and talents. On a final note Game Masters can have the final say of how a piece of mechanical information works in their game. If you live by the rules then find a way for the time line to work in the characters favor and ultimately the psychic abilities run concurrent to his age from the start of birth:}
