Secretary of State Al Jaeger says a deadline has passed for supporters of a proposed ballot measure that would require North Dakota's superintendent of public instruction to be a licensed teacher and spend at least 40 hours each year teaching in a classroom.

Supporters of the idea needed signatures from at least 25,688 eligible voters to be put on the statewide ballot.

Jaeger said the one-year deadline for circulating petitions passed Thursday and no petitions were submitted.
