Training is a must. How you learn can vary.
People who choose to become actuaries share some common interests. But the way they prepare for the work varies widely.
Many students pursue actuarial science during their university/college studies. However, majoring in actuarial science is not mandatory to be an actuary. No specialized degree is required to advance in the profession. Good fields of study for actuaries include math, statistics, finance, economics and business.
Ultimately, what matters is passing the actuarial exams and other components required to enter the profession. So, anyone considering an actuarial career should choose an education that will help prepare them to earn the credentials required to work as an actuary.
