NEW ORLEANS (AP) — The state agency that runs most New Orleans public schools and the city’s inspector general are ending an agreement that called for the IG to oversee a school construction plan.

The Recovery School District says the agreement is being ended because some of the oversight functions aimed at preventing fraud are already done by other agencies. The duplication of effort could affect federal re-imbursement of costs for the project.

The end comes amid disagreements between Inspector General Ed Quatrevaux and state education officials over the methods and scope of the IG’s oversight efforts, and the RSD’s obligations. Those disagreements were noted in letters released Friday by Quatrevaux and state Education Superintendent John White.

Quatrevaux said the RSD failed to make employees available for interviews, failed to provide records and violated the agreement in other ways.

White took issue with Quatrevaux’s claims.

“Your position that we are required to produce records and documents on demand without legitimate inquiry on our part as to whether or not the work is within the scope of our agreement is not reasonable,” White said in one letter.

The three-year, $1.2 million contract called for the IG to provide fraud oversight on the school building master plan funded with $1.8 billion in Federal Emergency Management Agency money. The Recovery District has already paid the inspector general about $271,000.
