The Professional Skaters Association International is the largest figure skating coaches association in the world. The PSA was founded on August 10, 1938 in Lake Placid, New York, as the American Skaters Guild, just two years (1936) after the Ice Teachers Guild was formed in England by Jacques Gerschwiler, Howard Nicholson, Gladys Hogg and Eric Van De Weyden.

On January 21, 1950, at the Broadmoor World Arena in Colorado Springs, Colorado, the American Skaters Guild was reorganized and renamed the Professional Skaters Guild of America.

In May 1995, the PSGA once again changed its identity to the Professional Skaters Association, International (PSA). With this new name the association took on a renewed role in the sport of figure skating, but vowed to remain rooted in its 57-year history and ideals. The “birth” of the PSA reflected the changing scope of this organization’s activities and of the worldwide skating industry. The Board of Directors felt it was time to adopt this new name, acknowledging that the PSA is the world’s premier professional skating organization. The PSA is the official figure skating coach’s education, training and accreditation program for U.S. Figure Skating and the Ice Skating Institute.

Probabilistic risk assessment (PRA) is a systematic and comprehensive methodology to evaluate risks associated with a complex engineered technological entity (such as an airliner or a nuclear power plant) or the effects of stressors on the environment (Probabilistic Environmental Risk Assessment - PERA) for example.

Risk in a PRA is defined as a feasible detrimental outcome of an activity or action. In a PRA, risk is characterized by two quantities:

Consequences are expressed numerically (e.g., the number of people potentially hurt or killed) and their likelihoods of occurrence are expressed as probabilities or frequencies (i.e., the number of occurrences or the probability of occurrence per unit time). The total risk is the expected loss: the sum of the products of the consequences multiplied by their probabilities.

The spectrum of risks across classes of events are also of concern, and are usually controlled in licensing processes – it would be of concern if rare but high consequence events were found to dominate the overall risk, particularly as these risk assessments are very sensitive to assumptions (how rare is a high consequence event?).

Probabilistic Risk Assessment usually answers three basic questions:

Two common methods of answering this last question are event tree analysis and fault tree analysis – for explanations of these, see safety engineering.

In addition to the above methods, PRA studies require special but often very important analysis tools like human reliability analysis (HRA) and common-cause-failure analysis (CCF). HRA deals with methods for modeling human error while CCF deals with methods for evaluating the effect of inter-system and intra-system dependencies which tend to cause simultaneous failures and thus significant increase in overall risk.
