American Society of Health-System Pharmacists (ASHP) will have the most resources for starting a residency search. I would highly recommend going to your local or state society of health-system pharmacists for local residency showcases. The largest and most comprehensive of these showcases will be at the ASHP mid-year conference that is in December of each year in varying locations. There you are able to speak with representatives of each program and get more information.
As far as timing, the best time to go to these showcases is during your 2nd - 3rd year of pharmacy school. 4th year is too late since most students are already completing applications around mid-year and most programs have deadlines in late December/early January.
Another important thing is to contact programs that you are particularly interested in and set up casual visits (pre-interviews if you will). This helps you stand out from other applicants and also familiarizes leadership with your name and face. Use contacts when you can - professors, family friends, etc. because in a competitive environment, getting your name out there and having someone vouch for you is very helpful.
For Texas specifically, most Colleges of Pharmacy have their own local residency showcases that are less overwhelming that the one at ASHP mid-year. In addition, local chapters of ASHP usually have mentoring programs that you can sign up for and have a mentor in the field you are interested. Often this mentor can be quite helpful in advancing your residency search.
This professional recommends the following next steps:
- Research residency programs on ASHP website
- Attend ASHP mid-year residency showcase and other local residency showcases as able.
