There are three groups, each made up of ten to twenty-five members (with no age limit), performing a single performance, whether it is a song and/or dance number or an acting performance. Before the performance, at least one member of the group is given 20 seconds to make an introduction in any way that reflects the group, but should end with the clause "It's Showtime!", but in the All Star Barangayan edition, their barangay will be given 30 seconds of their introduction but same process and the barangay with the best introduction will win P10,000. After the performance, the judges, as well as members of the audience, rate the group from 1 to 10. Audience ratings do not count, but can influence the ratings to be given by the judges.
A fourth competition spot is randomly given to one of three groups who did not pass the auditions, but are still worthy to perform in the show. After the group's performance, the judges would give a collective yes or no to the group. If the judges give a yes, the group is considered part of the main contest, with the judges' scores to the group's performance to be included in the calculation for the winner. A no would, of course, mean exclusion of the group from the main contest. This segment was removed during season 2. In season 3, during the February 16, 2011 episode, the said segment was returned but no random selection, instead the group automatically performs on stage.
The group with the highest average score from the judges wins and proceeds to the weekly finals. All winners throughout the whole week perform in the weekly finals. Whoever wins in the weekly finals will get the chance to compete in the monthly finals. Lastly, all the monthly finalists compete in a season grand finals.
Season 4 competition is open to everyone who has their talent, not only Groups joining, the competition will also open to Solo, Duo, and Trio performers. The season's change will also have a 1st Runner-Up, every competition, the group or performer with the second highest score will take home P20,000.
