Competitive dance is a popular, widespread sport in which competitors perform dances in any of several permitted dance styles--such as acro, ballet, contemporary, jazz, hip-hop, lyrical, modern, musical theatre, and tap--before a common group of judges. This is in contrast with other activities that involve competition among dancers based on purpose, or specific dance style, such as pom squad and dancesport. The competitive dance industry largely consists of competition production companies--also sometimes called dance competition companies and dance competition lines--that conduct regional competitions at stops along their annual, nationwide tours. Dancers who compete at these regional competitions are students ranging in age from approximately four to eighteen years old. Dance schools (often referred to as dance studios) arrange for their classes to compete as groups. Advanced dancers may be chosen to compete solos, duets, trios, or in a small group dance in addition to or in place of large group routines. Competitions typically begin in January and end in July or August.
Competitive dancers must be physically fit because even short dances can be physically demanding. Dancers must continuously train to maintain and improve their technique, balance skills, strength and flexibility. Except for holidays and short breaks during the summer, competitive dancing is typically a year-round activity: dancers attend classes during competition season, to refine their competitive routines, and during off-season to prepare for the next upcoming competition season. Some dancers attend dance intensives during the summer to improve technique. These intensives normally last a few weeks and happen in various locations across the world.
The music used in competitive dance routines is typically adapted from commercially available songs created by professional recording artists. Dance routines are subject to time limits at most dance competitions, and consequently the original, commercial music is usually edited to conform to such time limits.
Different styles of dance require different forms of music. Lyrical, contemporary, and modern dances often require slower music. Jazz and hip hop dances are set to more upbeat songs. The musical theatre category is composed of routines set to songs from Broadway musicals, films, and TV shows. 
There is no industry-wide standard for scoring. The maximum number of points issued by each judge, as well as the maximum possible final score, varies among competition production companies. Although it is common for judges to issue a maximum of 100 points each, at least one company implements a system in which judges may issue up to 200 points, based on the rationale that such a scoring system is similar to that employed in public schools. Although scoring at dance competitions vary, the judges score the performances based on similar qualities. The judges usually score based off technique, performance, costume, music, and challenge level of the performance. Each competition's ranks are different. For example some competition's highest medal may be a "gold", whereas another is a "crystal." The performances are usually ranked within the category of dance (Jazz, Ballet, Lyrical, Hip-Hip, etc.) The dances are also ranked "overall". This means that out of all the dances of that age group are ranked based on their score. Overalls include all different categories of dance.
Most competitions have opportunities for dancers to win title positions. Titles include Mr. and Miss dance. These competitions normally include elite dancers who choose to pay an extra fee to run for title. The title competition includes competing a solo, entering a headshot, and being interviewed by the judges. Winners of the title competition typically receive money and a crown.
Dance competitions are organized and conducted by independent competition production companies. In 2007 there were at least 150 such companies operating in the United States and Canada alone. Competition production companies move from one metropolitan area to another, stopping for a few days in each area to conduct a regional competition. By touring in this manner, these companies are able to generate profits while at the same time enabling significant numbers of dancers to attend local competitions. Some companies also conduct one or more national competitions after their regional tours have ended.
The competitive dance industry has no oversight body or standards organization, although at least one effort was attempted to establish a limited set of competition rules and safety standards in the industry. Competition production companies seldom coordinate their tours with each other. Tour start and end dates, as well as cities visited, vary from one company to another. Most companies conduct regional tours from approximately January through May, while National competitions generally run from June through August. It is not uncommon for two regional tours to be visiting the same metropolitan area at the same time.
Age Divisions: Dancers in competitions are split into different age categories. The categories are: 4 & under, 5-8 years old (mini), 9-11 years old (junior), 12-14 (teen), and 15-18 (senior). Dancers must bring proof of age to every competition in case their age is challenged. Dancers must stay within one age group of their own respective age group when dancing in groups with dancers of other ages.
Competition Levels: Dances are split into three categories based on difficulty level. These categories are beginner, intermediate, and advanced. Studio directors and choreographers decide which level a dance is placed in. If judges feel that a dancer is in the level, they may either disqualify the dance or bump it into its right category.
General Divisions: Solo (1 performer), Duo/trio (2-3 performers), small group (4-9 performers), large group (10-19 performers), line (19-24 performers), and production (25 or more performers)
The choreography of a dance routine--which is the design of movement and flow of steps in the routine--is copyrightable. Consequently, video recording is often prohibited at dance competitions in order to steer clear of copyright infringement issues. Some competition production companies employ professional videographers to capture and sell video recordings of competitive performances with the restriction that video recordings may only be sold to the subject performers or members of their studios, thus avoiding infringement. When no professional videographer is available, competition production companies will sometimes permit each attending dance school to designate a videographer to record performances of students from that school.
Unlike videography, still photography does not infringe copyrighted choreography. Because of this, many competition production companies permit photography at their competitions. Virtually all competitions prohibit flash photography, however, both for the safety of performers and to prevent undesirable distractions. Some competition production companies employ professional photographers to capture and sell photographs of dance performances. In such cases, photography by audience members is typically prohibited so as to provide an exclusive market for the official photographers.
