Originally, competitions were held in two formats, CCI and CIC (Concours International Combiné).
With the advent of the new format (which abolished phases A, B, and C), the FEI agreed to change the distances of the CCI to make it more difficult than the CIC competitions.
As of 1 January 2019, CCI competitions have been renamed to CCI-L (Long) and CIC to CCI-S (Short).
They are international three-day events, as opposed to a national competition or a one- or two-day horse trial.
Rules:[citation needed] Advanced level, for horses with some experience in international competition.
Rules: Intermediate level, for horses and riders with some experience riding in a three-day event, who are just starting to begin international competition.
The CCI1* introduced in 2019 has a stadium jumping height of 1.05m, can be organized as short or long format and is not compulsory for qualifications at the 2* level and above.
