The datasets are the assessor and participant self-evaluation raw scores. These cover the 29 horse riding exercises performed to assess the rider-horse body language to ensure clear rider-horse communication. These exercises cover the two basic elements needed for effective and safe horse control. These are speed control and direction control. Speed and direction control can be divided into four cornerstone exercises which form the basis of all horse riding, namely walk to halt; halt to walk; turn on the forehand; and walking on a straight line with a bend. The four foundation exercises create the first three elements of the Fédération Equestré Internationale training scales.
