The 10-year-old boy allegedly defiled by a member of the Society of Christian Doctrine (MUSEUM) started giving evidence in court this morning.
The case, against Anthony Callus, 46 of Siggiewi, who is also an assistant head of school, is being heard behind closed doors.
Mr Callus is also charged with violent indecent assault, harassment and offending public morals.
A request for bail last Thursday was refused until witnesses are heard.
