MONTREAL — A kindergarten student in Saint-Michel will be allowed to wear a noise-reducing headset in class, because her parents’ say their religious beliefs don’t allow the five-year-old girl to listen to music.

Though music is an integral part of the kindergarten program, the principal of Bienville School decided to grant the accommodation request made by a Muslim family and allow their daughter to block out music at school.

The school is considering offering an alternative course, designed specifically for Muslims, that avoids the pernicious influence of music altogether: Beheading For Beginners.
