Molly, my last post wasn't as helpful as I would have liked. Let me see if I can offer something more concrete and helpful:
1. As stated above definitely contact the programs which rejected you to seek as much specific information about what they considered to be the strengths and weaknesses of your application. You might also wish to send them a letter thanking them for their attention and consideration.
2. As stated in a different post by Trauma Nurse, consider taking advanced NP type courses such as patho-physiology, and or pharmacy as a non-matriculating student.
3. If you have any low science grades that stand out consider retaking those courses provided that you believe that you can do better.
4. Consider taking a public speaking course or consulting with a good "image consultant" who might be able to help you improve your interviewing skills.
5. See if there are any further advanced certifications that you can acquire. I assume that you are already CCRN certified. Consider becoming certified to TEACH various certifications, at least CPR. Then consider offering low cost or FREE CPR certification at some of the institutions to which you are interested in applying (this would be a GREAT benefit for their undergraduate BSN/ASN students).
6. Try to shadow a number of CRNA's and learn something relevent to use in a future interview or essay. Even if you have to pay them (which you probably won't) for the experience.
7. If your CRNA institutions emphasize serving "rural areas" then consider finding some volunteer work in this type of location. A visiting nurse service for the aged would be one excellent possibility. Perhaps even better would be ORGANIZING such an effort if it didn't already exist (in a rural area). This would show leadership, in additon to creativity.
8. See if there are any research opportunities available at the institutions you are interested in applying with. Even if you staffed the Anatomy and Physiology study room for undergraduates on a voluntary basis for a few hours a week, this could be useful (and it's a great A&P review).
9. Consider researching and publishing (you can self publish dirt cheap these days) a book on some aspect of anesthesia, or perhaps critical care nursing (a book that challenged some of the unproven aspects of "anesthesia awareness" might not be bad). If you think it necessary seek a current CRNA to act as an assistent, and to lend credibility to your work. Perhaps you could start a newsletter for undergraduates and RN's interested in becoming CRNA's, that also kept tract of various legislative initiatives. Consider producing a segment, or series of segments for National Public Radio, they have a reputation for allowing enthusiastic amateurs to produce informative segments on subjects where they have special insite (think NURSING). If nothing else should you form some sort of group or foundation consider UNDERWRITING one of their morning programs. It is incredible how many academic types listen to NPR in the morning and hearing "this segment is underwritten in part by the Molly S. foundation dedicated to the health of older Minnesota residents" couldn't hurt.
10. If you want to get "down and dirty" hire a PI to quietly ascertain various voluntary membership organizations that members of the selection board participate in. Then consider joining, and becoming active within those organizations. Choose wisely and use caution as this could hurt you if detected as phony. Also learn at least WHAT SCHOOLS likely members of your selection board attended. If you can also know something about those programs, it might prove useful the next time around.
11. If you happen to have wealthy relatives have them endow a nursing scholarship
fund at your University of choice. I know of a guy who was accepted into medical school at a certain location after his physician father donated around $500,000 to establish a scholarship fund (his kid had been previously rejected).
12. Consider taking a job in the ICU of the hospital that does clinicals for the CRNA program that you prefer. This might offer the opportunity to develop some useful contacts.
13. Consider starting a PAC that would push agendas at the STATE level importent to CRNA's. An example might be organizing people in various states to lobby for the Medicare "opt out" provision being adopted by more states. This would be a BAD idea IF the schools that you are interested in ALSO educate MDA's or have them on the selection boards. Another worthy group would focus on educating high school seniors about pursueing anesthesia as a career.
14. If you are relatively young try, try again. Consider the accumulated differences in LIFETIME earnings that being a CRNA might yield over your current pay (keeping in mind various investment OPPORTUNITIES that might present themselves with increased pay. Thus it's not just the extra 50K plus a year, it's the INTEREST which that income can EARN properly invested). Present these financial calculations to your husband (if applicable) and see if he doesn't think that moving might not be warrented (if necessary). Consider also that if you have kids that you will being setting an IMPORTANT example for how they should address adversity in their lives. Like a soldier who fights valliantly in battle your deeds may live long past this struggle. If you do move consider PA, they have the most CRNA schools in the nation. I have also been told that some schools in some states show preference for instate applicants. Persist until you succeed and you are guarenteed success. You were not put on this earth to fail and the fact that you are already seeking advice makes me confident that you won't.
Pray, even if you are agnostic. There is mounting scientific evidence to support prayer, and even mainline quantum physics has largely accepted the notion of non-locality even if they are not sure whether or not Shrodinger's cat is alive or dead. Let me start you out with one on the house "God please grant Molly the success that she deserves and bless her efforts that she may in turn bless others."
