The Home Advantage (HA) has been an important object of study in world football. Several researchers have sought to quantify HA in the international soccer, but when it comes to Brazilian soccer, few studies have been devoted to research in this area. The present study aimed at comparing the HA in the Brazilian Championship Series A and B. All the games were analyzed in terms of wins, draws and defeats at home, in the seasons from 2003 to 2009 in both series A and series B. To quantify the HA, we used the method of recovery percentage points, proposed by POLLARD (1986). There was a greater HA in Series B (69 ± 2.3%) compared to Series A (65 ± 2.3) (p < 0.05). It was concluded that, in Series B of the Brazilian Championship, the factor "play at home" has greater advantage than in the Brazilian Series A season.
