In our small school the upper grade room (grades 5-10) has student devotions once a week. Each week one student is responsible to lead the singing that morning and another is responsible for presenting a bible meditation and prayer. The girls came to my room (the lower grades) when it was their turn to lead singing or have devotions. The teacher has a rubric for giving feedback on the quality of their song leading and devotion preparation and presentation. For our whole school chapel the ninth and tenth grade boys take turns leading the singing. It gives them lots of practice before they are expected to lead out in a church service.
