This is a great question. In summary, being certified makes you more competitive for landing a position. The wonderful aspect of being a pharmacy technician is the variety of avenues you may take. You can work in retail (e.g., CVS), hospital, nuclear medicine, insurance company, or even the government!

I am a current pharmacy student in Indiana. I have been a pharmacy technician for several years and now I am a pharmacy intern since I am in school. I is a good idea to become a certified pharmacy technician because pharmacies will be more eager to employ you. You have to take a certification exam. In order to sit for the certification exam you have to either take a training program or have at least 500 hours of work experience. The exam does cost $129 so you will want to prep for the exam before you take it. You can re-take the exam in 60 days if you fail the exam. Being a certified pharmacy technician will open the door to many other job opportunities. Technicians can work in hospitals, retail pharmacies, compounding pharmacies, long-term care pharmacies, and so much more!

I hope this helps,
