every year the best samba school from the grupo de acesso is promoted to samba school of the grupo especial, and conversely the worse of the groupo special is demoted to grupo de acesso for the following year.

similarly, depending on the year, one or two of the worse performing samba school from the groupo de acesso get demoted to the grupo rio.

any of the samba schools in série a make a wonderful choice for anyone interested in marching in the parades.
