The Tucson Unified School District has been fined more than $1.9 million.
A state Department of Education audit found that TUSD failed to provide enough instructional hours for seventh- and eighth-grade students in the 2008, 2009 and 2010 school years.
Auditors say inadequate oversight and errors in developing bell schedules were to blame for the shortage.
The Arizona Daily Star says TUSD now has 30 days to appeal or pay the fine.
School districts receive state aid based on several factors related to student enrollment and attendance. They also must provide at least the statutorily required minimum number of instructional hours.
Auditors found that 17 of the 26 TUSD schools serving seventh-graders and eighth-graders didn’t provide at least the required 1,068 hours for one or more of the three years.
