Currently contested by ten clubs, it operates a system of promotion and relegation with the top-flight Serie A and the bottom-level Segunda Categoría.
For sponsorship reasons, it is known as the LigaPro Banco Pichincha Pymes.
With the creation of LigaPro for the beginning of the 2019 season, the format consisted of two separate round robin stages.
Additionally, the two teams with the fewest points at the end of the season are relegated to the Segunda Categoría.
The most successful team is Técnico Universitario, who won their sixth title in 2017, while the current champion is Macará.
