Para-equestrian classification is a system for para-equestrian sport. It is a graded system based on the degree of physical or visual disability and handled at the international level by the FEI. The sport has eligible classifications for people with physical and vision disabilities. Groups of eligible riders include The sport is open to competitors with impaired muscle power, athetosis, impaired passive range of movement, hypertonia, limb deficiency, ataxia, leg length difference, short stature, and vision impairment. They are grouped into five different classes to allow fair competition. These classes are Grade I, Grade II, Grade III, Grade IV, and Grade V(Grade Names Changed as of Jan 2017) . The para-equestrian classification does not consider the gender of the rider, as equestrines compete in mixed gender competitions.

In 1983, classification for cerebral palsy competitors in this sport was done by the Cerebral Palsy-International Sports and Recreation Association (CP-ISRA). They defined cerebral palsy as a non-progressive brain legion that results in impairment. People with cerebral palsy or non-progressive brain damage were eligible for classification by them. The organisation also dealt with classification for people with similar impairments. For their classification system, people with spina bifida were not eligible unless they had medical evidence of loco-motor dysfunction. People with cerebral palsy and epilepsy were eligible provided the condition did not interfere with their ability to compete. People who had strokes were eligible for classification following medical clearance. Competitors with multiple sclerosis, muscular dystrophy and arthrogryposis were not eligible for classification by CP-ISRA, but were eligible for classification by International Sports Organisation for the Disabled for the Games of Les Autres.

The CP-ISRA used the classification system designed for field athletics events. In 1983, there were five cerebral palsy classifications. Class 1 competitors could compete in the Division 1, Class 1 and Class 2 events, while riding with a leader and 2 siderwalkers and/or a backwalker. In 1990, the Equestrian Australia did not have specific classifications for competitors with disabilities. Acknowledging membership needs though, some rules had organically developed that looked like classifications based on rule modification for different disability types. These included acknowledging one-armed riders were not required to hold the reins in both arms, riders with hearing loss were given visual signals instead of audio signals at the start of and during an event, and blind riders, when they reached a marker, were given an auditory signal. When the sport was undergoing growth in 1995, a classification system was established in order to provide a level playing field for competitors. The system developed at the time was called "Functional Profile System for Grading" and was largely created by Christine Meaden, who had IPEC classifier status. By 1999, there were four classifications for competitors and 120 accredited equestrian classifiers around the world. At the New York hosted Empire State Games for the Physically Challenged, para-equestrian competition was broken into hearing and vision impaired classifications, amputee classifications, Les Autres, cerebral palsy and spinal cord disabilities.

At the 1996 Summer Paralympics, classification was done at the venue because classification assessment required watching a competitor play the sport. At the 2000 Summer Paralympics, 6 assessments were conducted at the Games. This resulted in 1 class change. Because of issues in objectively identifying functionality that plagued the post Barcelona Games, the IPC unveiled plans to develop a new classification system in 2003. This classification system went into effect in 2007, and defined ten different disability types that were eligible to participate on the Paralympic level. It required that classification be sport specific, and served two roles. The first was that it determined eligibility to participate in the sport and that it created specific groups of sportspeople who were eligible to participate and in which class. The IPC left it up to International Federations, in this case FEI, to develop their own classification systems within this framework, with the specification that their classification systems use an evidence based approach developed through research.

The fourth edition of FEI's classification system guide was published in January 2015.

Going forward, disability sport's major classification body, the International Paralympic Committee, is working on improving classification to be more of an evidence-based system as opposed to a performance-based system so as not to punish elite athletes whose performance makes them appear in a higher class alongside competitors who train less.

The purpose of classification to identify the level of functional disability of a rider, completely independent of their skill level. This is because demonstration of skill is the purpose of competition. Steps are taken before and during the classification process to avoid this. Part of the process involves observing the competitor riding and doing a bench press. For this reason, classifiers do not observe a rider on their horse prior to the bench press to avoid assessing skill at functionality.

During classification, classifiers look at several things including a rider's mobility, strength and coordination. This is done during a bench press, during training and in competition. After riders are classified, they are giving both a classification and a profile. This profile a number 1 to 39 for para-dressage and 1 to 32 for para-driving. This profile impacts what adaptive equipment riders can use.
