CRA is one thing, "Officer" is another
It sounds like at your bank, the position is not currently an officer level. Prior to my joining my bank, they were an officer, but without any other title (AVP, VP, etc).
As Don mentions and Len, CRA is not a duty to be taken lightly, unless you enjoy failure. I personally don't accept "appointments" (ie "You now do CRA ok?"). I am a professional and expect to be treated as such. You should be no different. (There's the career counseling portion of my speach)
Now to the CRA portion of my speach. I love CRA. I was hired with the understanding that it would not only be officer level but AVP (which was a stretch because this bank had only given those titles to lenders). I was currently a VP at another bank and they wanted me...so they gave me what I asked. I also asked for much more money than the prior person (this is not a job you should be paid poorly at!). Again, they wanted me. I was promoted in one year to VP, scandalizing the lending staff
(not all of them but it was a pretty funny reaction). I received the promotion because I am pretty darned good
at what I do, and I expect the respect due to me for that performance.
So officer or no officer, ask yourself first, do you want this? How does your bank feel about CRA? (What's you current rating and have you read your performance eval yet?) Will they support you if you throw yourself all into this challenge, or are you supposed to do this and produce loan docs too? If the answers are positive, go back and say "yes" I'll take the challenge, but I expect officer level in six months, and AVP in "whatever makes sense at your bank".
I will tell you, lenders are silly beasts (I used to be one so I know first hand). They know who the bank respects, and often cast their respect in the same direction. If you want to be successful in this position, you MUST HAVE lender support as well as senior management. You need their help in reporting correctly, etc., and if they don't respect you, they won't make the effort and you will fail.
Go forth and kick arse
I've done it all in banking, and frankly made much more money than I do now, but never loved my job as much as I do now.
