SIBLEY, Iowa — Class was in session as normal Monday at Sibley-Ocheyedan High School after an investigation into a student assignment detailing a school shooting was determined not to be a credible threat to student or public safety, a public release on the district’s Facebook page announced after noon Monday.

According to the public release, Northwest Iowa Community College (NICC) notified the Sibley-Ocheyedan school district over the weekend to report one of its high school students enrolled in an online college course had submitted an assignment that described what would happen leading up to, during and after a school shooting.

An investigation began between the school district, NICC and the Osceola County Sheriff’s Office.

According to S-O Superintendent James Craig, the general writing assignment was posted to a discussion thread that could be read and reviewed by other students. Upon further investigation, it was determined the student's writing example was topical and did not create a threatening position toward the district.

Concerns had been brought forward to the district from students and parents, which initiated the action the district took when addressing it publicly on its Facebook page.

"We felt it important to get that message out right away," Craig said.
