Indiana schools will not receive their "A-F" school grades for at least another three weeks.
The State Board of Education voted Wednesday to delay their release because of problems with how International Baccalaureate scores were recorded for a small number of schools. The new scores will not be approved before the board meets again Nov. 5.
Questions about how the International Baccalaureate scores were recorded reignited fighting between Democratic Schools Superintendent Glenda Ritz and Republican appointees to the school board.
Board Member David Freitas said the problems calculating the grades showed a "lack of leadership" from Ritz's Department of Education. Ritz's staff said they identified the problem and were addressing it.
Indiana's school grading system is undergoing an intensive review following problems discovered in last year's grade-change scandal.
