TULSA, Okla. (AP) - State education officials say Tulsa Public Schools may have to compensate special education students who didn't receive services they were entitled to at the troubled Tulsa Academic Center.

The state Department of Education has told school officials that the district violated a host of requirements in the federal Individuals with Disabilities Education Act.

The Tulsa district now has a series of deadlines over the next two months to respond to the state's findings and to develop plans for improving services, documentation and discipline procedures for all special education students.

In mid-March, the Tulsa World began a series of stories documenting teacher, parent and student accounts of overcrowding and frequent violence at the alternative school.
