Choosing what level you want to work at or achieve is a personal preference. Many people truly enjoy working with the elderly and though they have earned the PCT certification, they use it solely to work as a CNA. Having the additional certification does make them a more competitive applicant and it is education that can’t be taken away, so if they ever choose to work in a different capacity they have the qualifications. Some people don’t like needles, so working as a Phlebotomist isn’t for them. Why someone would do something will vary from one person to the next. Visit a school, see what the programs are like and which feels the best for you. Think about where you’d like to work and the type of patients you’d like to help.
