Things get more complicated during the school year. So the government came up with some rules.
In June 2014, the Ministry of Internal Affairs (MIA) reviewed the licenses of Poro and Sande societies, with the involvement of elders and chiefs and stated that violators would bear the full penalty of the law.
The Bureau of Customs and Cultural Affairs of the MIA in collaboration with the National Council of Chiefs, Elders and Zoes urged their council members throughout the country to carry out their functions within the confines of traditional laws and guidelines governing the practices of Poro and Sande societies.
However, the MIA reiterated that no Poro, Sande or Zoe conductor shall initiate any child or any student into a grove during the normal school year.
I suspect that the thousand-year-old Poro (for boys) and Sande (for girls) society leaders consider the MIA to be upstarts. I'd be almost sympathetic--but both societies have some ugly practices; for example the Sande is reported to be heavily into FGM.
Three years ago there was talk of banning the Sande, but as that article says:
But some town elders say the government’s efforts to suspend Sande are just “mouth talk” and there is a way around everything in Liberia.
