Actuarial examinations in the United States are offered in a series by the following two major actuarial organizations:
A complete description of all examinations is given in catalogs published by the Society of Actuaries and Casualty Actuarial Society. There is also extensive amount of information at this site: http://www.beanactuary.org/exams/. You must use an approved calculator on the examinations. Information about approved calculators is provided in the catalogs. Note that the Casualty Actuarial Society has recently added two insurance-practice oriented examinations, Online Course 1 and Online Course 2, as explained here: http://www.casact.org/admissions/process/. The material on these examinations is covered in classes offered by the Finance, Insurance and Law Department of Illinois State University, Online Course 1 in FIL 250 and FIL 355, and Online Course 2 material is covered in several other FIL offerings.
For Illinois State University students should be aware of this: the examination center number in Bloomington, Illinois, is 064, and the college identification code for Illinois State University is 1422. The examination center in Bloomington, Illinois, is located in the corporate headquarters of State Farm, on Veteran's Parkway, near the intersection with Washington Street. Unfortunately, this information does not apply to the Computer Based Testing (CBT) for Course P/1, Course FM/2, and Course C/4 examinations -- while our students must take these as CBT, there is no CBT testing center in Bloomington, the nearest center is in Peoria, Illinois, and the next closest one is in Champaign, Illinois, there is also a center in Springfield, Illinois, and you can take an Amtrak train from ISU campus to Springfield, so this may be the most convenient one to use. Locations of centers for CBT can be obtained here: http://securereg3.prometric.com/Dispatch.aspx.
